Timeline
11.1) What is the history of Atari's 8-bit computers platform?
Subject: 1.1) What is an Atari 8-bit computer?
Based in Silicon Valley in the U.S.A., the company known as Atari produced
a line of home computers from 1979 to 1992 often referred to collectively as
the "Atari 8-bits," the "8-bit Ataris," the "400/800/XL/XE series," etc.
The computers included the 400, 800, 1200XL, 600XL, 800XL, 65XE, 130XE, 800XE,
and the XE video game system.
Notable home computers that were introduced before the Atari 400/800:
1977: Apple II, Tandy Radio Shack TRS-80 (Model I), Commodore PET
Notable home computers that were introduced after the Atari 400/800:
1979: Texas Instruments TI-99/4
1980: Commodore VIC-20, TRS-80 Color Computer, Osborne 1
1981: Texas Instruments TI-99/4A, IBM PC, Sinclair ZX81 / TS 1000, BBC Micro
1982: Kaypro II, Sinclair ZX Spectrum, Commodore 64
1983: Coleco Adam, MSX
1984: Apple Macintosh, Amstrad CPC
1985: Atari ST, Commodore Amiga
1987: Acorn Archimedes
In marketing their computers to the public, Atari always had to contend with
their company history and reputation as a maker of video games. While the
8-bit Atari computers in their heyday were technically quite comparable if not
superior in the worlds of home and business personal computing, they also live
up to the name "Atari" with a huge library of video games which were often
outstanding for their time.
The 8-bit Atari computers do not use the same cartridges or floppy disks as
any other Atari platforms, such as the 2600 Video Computer System (VCS), the
5200 SuperSystem, the 7800 ProSystem, or the ST/TT/Falcon computers. All of
these but the 5200, however, do share the same joystick/controller hardware
port.
The 5200 SuperSystem is actually nearly identical to the 8-bit computers
internally, yet cartridges for the 5200 and the 8-bit computers cannot be
exchanged, primarly due to the physically different cartridge ports.
Here are some of the performance specifications of the 8-bit Atari computers:
(Some of the rest of this section by Bill Kendrick)

+ require the GTIA chip. 1979-1981 400/800's shipped with CTIA
++ Not available via the BASIC GRAPHICS command in 400/800's.
GRAPHICS INDIRECTION (COLOR REGISTERS AND CHARACTER SETS):
Nine color registers are available. Each color register holds any of 16
luminances x 16 hues = 256 colors. (Four registers are for player-missile
graphics.
Character sets of 128 8x8 characters, each with a normal and an inverse
video incarnation, are totally redefinable.
PLAYER-MISSILE GRAPHICS: (byte height and OR corrections from Piotr Fusik)
Four 8-bit wide, 120 or 240 byte high single color players, and four
2-bit wide, 120 or 240 byte high single color missiles are available.
A mode to combine the 4 missiles into a 5th 8-bit wide player is also
available, as is a mode to OR colors or blacken out colors when players
overlap (good for making three colors out of two players!) Players
and missiles have adjustable priority and collision detection.
DISPLAY LIST INTERRUPTS (DLI's):
Screen modes can be mixed (by lines) down the screen using the Display
List - a program which is executed by the ANTIC graphics chip every
screen refresh:
All other screen attributes (color, player/missile horizontal position,
screen width, player/missile/playfield priority, etc.) can be ajusted
at any point down the screen via DLI's.
SCROLLING:
Fine scrolling (both vertical and horizontal) can be enabled on any
line on the screen.
SOUND:
Sound is monaural/monophonic (one channel output).
Up to 4 separate simultaneous voices can be produced, configured as one of
the following:
- 4 voices, each with one of 256 unique frequencies/pitches
- 2 voices, each with one of 65,536 unique frequencies/pitches
- 1 voice with one of 65,536 pitches and 2 voices with one of 256 pitches
Each voice may be produced with one of 8 available "noise" settings/
polynomial-counter combinations, commonly called "distortion" settings.
(There are actually only 6 distinct combinations of 3 poly-counters
offered, but one of the poly-counters has 2 available settings itself,
resulting in 2 additional noise settings for the total of 8 available.)
Each voice may be produced at one of 16 volumes.
Direct control of the position of the speaker cone is also available, with
4-bit (16 position) resolution. Known as "volume only mode" on the Atari.
A fifth "voice" is produced as a separate signal by the internal speaker
on the Atari 400/800. This is typically used only for keyclick and
buzzer. In XL/XE systems these sounds are output as part of the normal
monaural audio output signal.
Subject: 1.2) What is the Atari 400?
Released along with the 800 in 1979, the 400 was the low-end model of the two.
The only 8-bit Atari with a membrane keyboard rather than a full-stroke
keyboard. One of the few 8-bit Ataris lacking a composite monitor port.
Originally released with just 8K RAM, but most were sold with 16K RAM.
Atari sold the 48K RAM Expansion Kit for the 400, which required a little
soldering, to dealers only.
Only the 400 and 800 8-bit Atari models have four controller (joystick) ports.
The 400 was produced in both NTSC (North America) and PAL (Europe) versions.
Early 400 units contain the CTIA chip; later units, including all European/PAL
units, contain the GTIA chip, which is also present in all later 8-bit Ataris.
Atari marketing used the trademark, The Basic Computer, as an alternative name
for the 400 from 1981-1982.
The 400 was made in the USA (early production) and Hong Kong (later).
Production of the 400 ended in May 1983.
Subject: 1.3) What is the Atari 800?
Released along with the 400 in 1979, the 800 was the high-end model of the
two. The 800 is the only 8-bit Atari with a Right Cartridge slot, in addition
to the Left Cartridge slot as present on all 8-bit Ataris. Originally
released with just 8K RAM, many were sold with 16K, later on 48K was standard.
The 800 is also the only 8-bit Atari with a four-slot modular design, where
the first slot holds the CX801 (CX801-P for PAL machines) 10K ROM module, and
the other three slots hold combinations of CX852 8K or CX853 16K RAM modules.
Only the 400 and 800 8-bit Atari models have four controller (joystick) ports.
Jason Harmon writes: (12 Feb 2004)
"..the early ones had plastic cases on the ROM and RAM modules, and had two
thumb tabs to remove the cover to access the modules. Later model 800s had
48K standard, and to improve cooling Atari installed them without the cases
but put a small plastic strip across the tops of the cards to hold them in
position. These machines also lost the thumb tabs and have regular screws to
secure the cover over the memory slots."
The 800 was produced in both NTSC (North America) and PAL (Europe) versions.
Early 800 units contain the CTIA chip; later units, including all European/PAL
units, contain the GTIA chip, which is also present in all later 8-bit Ataris.
The 800 was made in the USA.
Production of the 800 ended in May 1983.
Subject: 1.4) What is the Atari 1200XL?
Introduced as a big brother to the 400/800 in 1982 and shipped in 1983, the
1200XL now uses Atari's slightly customized 6502C microprocessor, SALLY, and
includes a full 64K RAM. The 1200XL was the first 8-bit Atari with just 2
controller ports. In addition, the 1200XL includes 4 programmable Function
keys and a Help key, 4 LEDs, built-in diagnostic and graphics demonstration
programs, and probably the favorite keyboard of any 8-bit Atari computer.
Clicks previously output through the built-in speaker are now heard from the
television or monitor's speaker. The revised 16K Operating System offers many
new features, including an alternate International Character Set.
The 1200XL was the biggest single step forward in development of the 8-bit
Atari platform, but the corresponding software compatability problems hurt its
popularity.
The 1200XL lacks the separate chroma video signal on the Monitor port, and the
machine also lacks the +5 Volts power on pin 10 of the SIO port.
The 1200XL was produced in an NTSC (North America) version only. There is no
PAL (Europe) version of the 1200XL.
The 1200XL was discontinued in June 1983.
According to 1200XL serial number analysis by Karl Heller (2007), about
105,000 1200XL units were produced in total:
o From Mid March to late May USA production was about 78500 units in not so
sequential order.
o From early April to late June Taiwan produced about 26000 units in
perfect sequential order.
AtariAge thread: http://www.atariage.com/forums/index.php?showtopic=107234
Scott Stilphen mentioned this 1200XL easter egg on 10 Feb 2006:
On 1200XLs, if you select 'all tests', when it gets to the keyboard test
it'll type out the programmer's name.
Subject: 1.5) What is the Atari 600XL?
Released in 1983 as a replacement for the 400, the 600XL is the low-end
version of the 800XL. The 600XL/800XL include most of the features of the
1200XL minus the Function keys and the demo program. But both the 800XL and
600XL have the Atari BASIC language built-in. In addition, these two systems
offer the Parallel Bus Interface (PBI), providing fast parallel access to the
heart of the computer. The 600XL has 16K RAM.
The 600XL can be expanded from 16K to 64K with the Atari 1064 Memory Module.
Normally boots with Atari BASIC (Revision B) enabled; Hold down [Option] on
startup to boot without BASIC.
The 600XL was produced in both NTSC (North America) and PAL (Europe) versions:
o NTSC (North America), produced fall 1983 to summer 1984 by Atari, Inc.
- No composite Monitor port
o PAL (Europe) version, produced fall 1983 to summer 1984 by Atari, Inc.
- Includes Monitor port, but this lacks the separate chroma video signal
Rare variations of the 600XL:
o Some late-model 600XLs were sold with 64K RAM. These may have only
appeared in Canada. The box had a round gold foil sticker reading: "64k
Memory -- Now with a full 64k of memory built-in."
5 different types of 600XL/800XL keyboards were nicely documented by Beetle

Subject: 1.11) What are the SALLY, ANTIC, CTIA/GTIA, POKEY, and FREDDIE chips?
Some of the following text is taken from De Re Atari (Atari#APX-90008), a book
published by Atari through the Atari Program Exchange (APX) and copyright 1982
by Chris Crawford, et al. See http://www.atariarchives.org/dere/ where the
full text of De Re Atari is now available online.
The internal layout of the Atari 8-bit computer is very different from other
systems. It of course has a microprocessor (a 6502), random-access memory
(RAM), read-only memory (ROM), and a peripheral interface adapter (PIA; a
6520). However, it also has three special-purpose large-scale integration
(LSI) chips known as ANTIC, CTIA or GTIA, and POKEY. These chips were
designed by Atari engineers primarily to take much of the burden of
housekeeping off of the 6502, thereby freeing the 6502 to concentrate on
computations. While they were at it, they designed a great deal of power into
these chips. Each of these chips is almost as big (in terms of silicon area)
as a 6502, so the three of them together provide a tremendous amount of power.
Mastering the Atari 8-bit computers is primarily a matter of mastering these
three chips.
6502/SALLY Central Processing Unit (CPU) -- SALLY,XL/XE:CO14806
==========
While the 400/800 models contain a generic 6502B CPU (a faster version of the
original 6502A microprocessor), all of the XL/XE models contain Atari's
customized 6502C chip, known as SALLY.
On the Atari, there are two microprocessors, ANTIC and the 6502. To allow
them to coexist, ANTIC must shut off the 6502, a process called DMA. The
6502B supports DMA, but in Atari's implementation, it required 4 chips. The
6502C has an extra line called HALT. It is controlled by ANTIC which uses it
whenever it needs the data/address bus. The HALT line is on pin 35 of the
Atari 6502C and must be pulled high for the chip to work.
ANTIC -- 400/800,NTSC:CO12296 400/800,PAL:CO14887
===== XL/XE,NTSC:CO21697 XL/XE,PAL:CO21698
ANTIC ("Alpha-Numeric Television Interface Circuit") is a microprocessor
dedicated to the television display. It is a true microprocessor; it has an
instruction set, a program (called the display list), and data. The display
list and the display data are written into RAM by the 6502. ANTIC retrieves
this information from RAM using direct memory access (DMA). It processes the
higher level instructions in the display list and translates these
instructions into a real-time stream of simple instructions to GTIA.
CTIA/GTIA -- CTIA,NTSC:CO12295 GTIA,PAL:CO14889
========= GTIA,NTSC:CO14805 FGTIA,SECAM:CO20120
CTIA ("Color Television Interface Adapter") / GTIA ("Graphics Television
Interface Adapter") is a television interface chip. ANTIC directly controls
most of GTIA's operations, but the 6502 can be programmed to intercede and
control some of GTIA's functions. GTIA converts the digital commands from
ANTIC (or the 6502) into the signal that goes to the television. GTIA also
adds some factors of its own, such as color values, player-missile graphics,
and collision detection.
Alternate acronym expansions (who can say which are official?)
CTIA:
"Color Television Interface Adapter"
"Colleen Television Interface Adapter"
GTIA:
"Graphics Television Interface Adapter"
"George's Television Interface Adapter" (George McLeod, chip designer)
"General Television Interface Adapter"
Early North American 400/800 models shipped with CTIA. Later 400/800
models, all European 400/800's, and all later 8-bit Ataris included GTIA.
Jerry Jessop adds:
"The very first proto systems did have the GTIA, but it had some
problems and was not released in the consumer version until 1981. The
GTIA was completed before the CTIA."
In BASIC, type POKE 623,64 [RETURN] and if the screen blackens, you have the
GTIA chip. If it stays blue, you have the old CTIA chip.
Clay Halliwell provides this tidbit:
A bit of trivia: CTIA 400/800s artifact in blue/green, GTIA 400/800s
artifact in green/blue, and all XL/XEs artifact in red/blue.
Atari designed a version of GTIA called FGTIA for SECAM video output (France).
This was utilized in SECAM versions of the 800XL, 130XE, and XE game system.
Prior to fall 1984, Atari sold PAL systems in France. In French-marketed
machines with the PAL GTIA, "the Lum outputs are run into an onboard encoder
to produce a "pseudo" color depending on the Luminance output, composite
only." (Jerry Jessop) The result is a reduced number of available colors.
POKEY -- CO12294
=====
POKEY (name derived from POtentiometer and KEYboard) is a digital input/output
(I/O) chip. It handles such disparate tasks as the serial I/O bus, audio
generation, keyboard scan, and random number generation. It also digitizes
the resistive paddle inputs and controls maskable interrupt (IRQ) requests
from peripherals.
All four of these LSI chips (6502/SALLY, ANTIC, CTIA/GTIA, POKEY) function
simultaneously. Careful separation of their functions in the design phase has
minimized conflicts between the chips. The only hardware level conflict
between any two chips in the system occurs when ANTIC needs to use the address
and data buses to fetch its display information. To do this, it halts the
6502 and takes control of the buses."
FREDDIE -- CO61922, CO61991
=======
The 65XE/130XE/800XE/XEGS contain a small additional LSI called FREDDIE, a RAM
address multiplexer. According to James Bradford, "FREDDIE is a type of
memory controller. It takes the address and clock from the CPU and
multiplexes it with the appropriate timings and signals to use DYNAMIC memory.
FREDDIE also buffers the system clock crystal and divides it down then feeds
that to GTIA. The XEGS has a FREDDIE but it doesn't have the extended RAM.
Even if it did, you would still need the chip that does the REAL bank
switching. It is a small 16-pin chip (Atari/Best Electronics catalog number
CO25953: rev9/page 42). It gets RAS from FREDDIE, the bank select bits from
PIA, A14, A15 and the 6502 halt signal to control which bank of 8 chips RAS
goes to. A14 and A15 then go to FREDDIE for the address range of the extra
memory bank (or normal address range with no bank switching). The ANTIC/6502
select bits in combination with the 6502 halt line, control the switching of
the PIA bank number bits to A14/A15 and which bank of memory RAS goes to. Why
people say FREDDIE does the bank switching is beyond me. An 800XL can look
like a 130XE with that 16-pin chip installed (That's right NO FREDDIE) and an
extra 8 RAM chips."
And more recently James Bradford has written:
FREDDIE is just a memory decoder and timer. It replaces several chips in the
800XL. The small chip near FREDDIE does all the bank selection. CO25953. One
line from FREDDIE, Ras (or is it cas?) goes to this chip, Halt and the bank
/processor select lines go into this same chip and ras (cas?) comes out. A pin
for each bank. If I remember correctly, refresh also goes into this small
chip. It would be quite easy to make an 800XL work just like a 130XE with this
chip since Ras (Cas?) is required by ALL dynamic RAM.

Subject: 1.14) What issues surround NTSC vs PAL versions of the 8-bit Atari?
Contributors to this section:
Wayne Booth, Graham Thornton, Brent Buescher Jr., Thomas Richter, Jindroush,
Sc0rpi0. Thanks especially to Piotr Fusik for his extensive help with this
section.
Some quick definitions first:
NTSC: "National Television Standards Committee"
TV signal standard used in North America, Central America, a number of South
American countries, and some Asian countries, including Japan.
o 525 lines per frame
o 60 half-frames per second (interlaced) = 60 Hz
o Complete frame refreshed 30 times per second
PAL: "Phase Alternation by Line"
TV signal standard used in the United Kingdom, most of the rest of Europe,
several South American countries, some Middle East and Asian countries,
several African countries, Australia, New Zealand, and other Pacific island
countries.
o 625 lines per frame
o 50 half-frames per second (interlaced) = 50 Hz
o Complete frame refreshed 25 times per second.
SECAM: "Sequentiel couleur avec memoire"
TV signal standard still used in France, the former USSR, and some African
countries. Until the 1980's SECAM was the standard in eastern Europe,
including East Germany, Poland, Czech Republic, Slovakia, and Hungary.
o 625 lines per frame
o 50 half-frames per second (interlaced) = 50 Hz
o Complete frame refreshed 25 times per second.
In some ways the specifications of the hardware in the 8-bit Atari computer
are closely linked to the specifications of the television signal standard
used in the market where the machine is designed to be used. Thus there were
generally two versions of each 8-bit Atari computer model produced: one for
NTSC markets, containing NTSC versions of the ANTIC and GTIA chips, and one
for PAL markets, containing PAL versions of the ANTIC and GTIA chips.
Atari Corp. also designed SECAM-specific versions of some of the 8-bit Atari
computers, including the 800XL, 130XE, and XE game system. Regarding
the following discussion, SECAM machines would behave the same as PAL
machines.
Piotr Fusik writes (3/06):
In Poland we had PAL Ataris, which was a problem at the times
of SECAM. You could connect a PAL Atari to a SECAM TV, but there was
no color and (IIRC) no sound. The solution was to buy an inexpensive
converter mounted inside the TV, so the TV supported PAL in addition
to SECAM. This was quite popular, because the VCRs were PAL, too.
Now then, what might happen if you run a software program designed with an
NTSC Atari on a PAL Atari, or a program designed with a PAL Atari on an NTSC
Atari? There are a number of possibilities:
1) The program may run faster or slower than intended.
All hardware timing is slightly different between NTSC and PAL machines, so
most programs run slightly faster on NTSC, slightly slower on PAL. This can
be significant in applications that are computation- or timing-sensitive, such
as music players, or in any programs designed to simulate real time.
2) The program may exhibit some sort of "screen flickering" effect, or the
system may completely hang.
The NTSC versions of the ANTIC chip generate a video signal with a screen
refresh rate of about 60Hz, whereas the PAL versions of the ANTIC chip
generate a video signal with a screen refresh rate of about 50Hz. The slower
refresh frequency of PAL machines translates into more available computation
time per screen frame. Computation-intensive software written for PAL
machines that assumes more available time per screen frame than is available
on NTSC machines will not run correctly on NTSC machines.
3) The colors displayed by the program are not what was intended.
The following two paragraphs are compiled from postings by Thomas Richter:
While NTSC machines contain a single system clock crystal oscillator, in
PAL machines a second oscillator that runs at 5/4 of the main system clock
frequency is present to generate the color frequencies needed to drive
GTIA.
This factor of 5/4 is the reason why you don't get the popular "artifacted
colors"/"pseudo-colors" (or, at least, not very good ones) in the ANTIC-F
(Graphics 8) mode when displayed with a PAL Atari.
As a result, programs that are written with assumptions about color
artifacting effects, which vary depending upon the color CRT display device
used, will also vary in appearance depending upon whether the machine is NTSC
or PAL.
Also, the actual palettes of colors that can be generated by the computer
look somewhat different depending upon whether the machine is NTSC or PAL.
4) The program may explicitly refuse to run on incorrect hardware.
Software (some demos) may be designed to determine whether the Atari is NTSC
or PAL, and refuse to run if the hardware present does not match what is
expected.
Typically, NTSC/PAL is determined by checking the "PAL" memory register
provided by the OS, which is based on the version of GTIA that is present:
Memory location 53268 ($D014, "PAL") indicates whether the system contains
an NTSC or a PAL GTIA. In Atari BASIC, PEEK(53268) returns 15 if an NTSC
GTIA is present, or 1 if a PAL GTIA is present.
Alternatively, software may determine NTSC/PAL by determining how many
scanlines are being generated by ANTIC. The NTSC ANTIC generates 262
scanlines, while the PAL ANTIC generates 312 scanlines. This technique is
utilized by the "Numen" demo by Taquart, which refuses to run on an NTSC
ANTIC.
5) The program may not load correctly at all.
This would mostly likely result from copy protection techniques based upon
precise hardware timing associated with disk drives, cassette recorders, or
components of the computer itself, where the timing was not anticipated to
vary depending upon NTSC vs. PAL hardware.
According to Jindroush (2/26/02), two examples of programs that run on NTSC
machines but not PAL machines as a result of timing-based copy protection
techniques (probably based on vblank timing) are Transylvania and The Quest
by Penguin Software.
6) The program may run fine on both NTSC and PAL machines.
Either the differences are too slight to matter, or the software may be
sophisticated enough to detect NTSC vs PAL hardware, as described above, and
act accordingly.
An examples of a program that alters its behavior depending upon detection of
NTSC versus PAL is Ghostbusters by Activision (checks for NTSC/PAL GTIA).
Bottom line:
============
Software written for NTSC machines (North America) will (almost) always work
on PAL machines (Europe), but software designed on PAL machines won't
necessarily work on NTSC machines.
Replacing the NTSC ANTIC chip in an NTSC Atari with a PAL ANTIC changes the
screen refresh rate to 50Hz, allowing most of the PAL-only European software
to run on a North American NTSC Atari. However, make sure your display device
can support a 50Hz PAL signal first! North American Atari users can also
obtain and use real European PAL Atari machines, with the same caveat
concerning the display device.

Subject: 2.1) What video display devices and speakers can I use with my Atari?
Contributors to channel output variations list:
Jon Levy, Rene de Bie, Sysop Fox-1
The Atari 8-bit computers produce a single video signal and monophonic audio.
The 400/800 models also produce some sounds (primarily the keylick and system
buzzer sounds) by way of an internal speaker.
Most 8-bit Atari computers put out their video and audio signals in two
places:
1) Television cable (400/800) or jack (XL/XE)
This provides a Radio-Frequency (RF) signal carrying both audio and video.
Atari computers were manufactured in two versions: NTSC versions for markets
where televisions support the NTSC signal standard (North America and
elsewhere), and PAL versions for markets where televisions support the PAL
signal standard (Europe and elsewhere).
Any standard television with an analog tuner (NTSC or PAL, matching the
version of the computer) and support for an external antenna should be able to
display the Atari's RF signal. If the television has a speaker then it should
support the Atari's sound output as well.
The RF signal is either available on one VHF channel, or on one of two VHF
channels selectable by a switch on the computer. The channels supported
depends on the market that the version of the Atari was desgined for:
North American computers: VHF channels 2-3 switch-selectable;
channels 3-4 switch-selectable also reported
European computers: VHF channel 4, no switch;
channels 3-4 switch-selectable also reported
UK computers: VHF channel 36, no switch;
channels 38-39 switch-selectable also reported
Australian computers: VHF channel 1, no switch;
400/800: channels 1-2 switch-selectable
Accessories needed (typical setup):
a) RF Cable / TV Video Cable, a proprietary cable for Atari XL/XE computers
The input end is a phono plug that plugs into the Switch Box/
Television jack on the computer. The output end is a phono plug that
plugs into the TV Switch Box.
The 400/800 models have no Switch Box/Television jack. Instead, there is
a cable that comes out of the back of the computer. This cable carries
the RF signal. The output end is a phono plug that plugs into the TV
Switch Box.
b) TV Switch Box
This includes a phono jack for RF signal input from the Atari, input
connector(s) for your TV/cable/satellite attenna, and 75- and/or 300-ohm
VHF output connector(s) for connection to the VHF input on the
television.
While display quality of the RF video signal may be adequate, the quality of
the video signals provided at the Atari's Monitor port are noticeably
superior.
2) Monitor port
A proprietary 5-pin DIN Monitor port, which along with the audio signal
actually provides two video signals:
a) Composite video
b) Y/C Video, also known as S-Video:
separate composite luminance (Y) and chrominance (C) signals
The separate chroma/luma video signal is noticeably superior to both the RF
television output and the composite video output.
Monitor port exceptions among Atari computer models:
-the 400, North American 600XL, and XE game system lack the Monitor port.
-the XE game system includes a phono jack providing the composite video
signal, and also a phono jack providing the audio signal.
-The 600XL, 800XL(most) and 1200XL lack the separate chrominance/luminance
signals at the Monitor port. (But the signals exist internally, and it is a
popular hardware modification to make them available at the Monitor port as
they are on the 400/800/XE models.)
Any video display monitor that supports composite video input (this generally
includes modern televisions) should be able to display the Atari's composite
video signal. Monitors with built-in speakers for audio support, and monitors
with support for separate chroma/luma video inputs, are preferred for use with
the Atari.
Commodore produced many monitors with separate chrominance and luminance
inputs, making them popular with Atari users. Lonnie McClure provides this
list of suitable Commodore monitors:
1701, 1702, 1802, CM-141, 1080, 2002, 1902, 1902A*, 1084**, 1084S**
* The 1902A used a DIN connector for chroma/luma, which makes cabling a
bit more of a problem. The composite and audio connectors are standard
phono jacks, however.
** The 1084 and 1084S had more than one version. Some used the a DIN
connector for chroma/luma connections, like the 1902A, while some used
standard phono jacks.
The 1902 and 1902A are very different in appearance. The original 1902
shares the same slightly rounded front case design as the 1080 and 2002,
while the 1902A is has a rather square case design, and was manufactured
by Magnavox (as were some of the 1084 and 1084S versions).
The pinout for the Atari Monitor port is in the pinouts section of this FAQ
list.
The typical Atari monitor cable includes the male 5-pin DIN connector on one
end, and two phono plugs on the other end. One of the phono plugs will carry
the monophonic sound signal, and the other will carry the composite video
signal. Atari's own CX89 Color Monitor Cable is of this type.
You may find an Atari monitor cable where the video signal carried on the
second phono plug is not the composite video signal, but is rather the
composite luminance signal. These cables are for use with monochrome
composite video monitors (usually green or amber). Atari's own CX82 Black
and White Monitor Cable is of this type.
The ideal Atari monitor cable includes 4 phono plugs at the output end,
carrying the sound signal, the composite video signal, the composite
luminance signal, and the composite chrominance signal. Only the best
composite monitors include separate chrominance and luminance inputs. When
the separate chrominance and luminance connectors are used, the composite
video connector is not used.
There is no real standard for colors for the different monitor cable
connectors. It is safe to identify them by trial and error.
The separate composite chrominance and luminance signals that the Atari puts
out comprise what the world has since come to call Y/C video or S-video.
S-video connectors are normally Mini4. It is possible to build a cable, or
purchase several adapters, that can allow you to utilize the separate Y/C
signals generated by the Atari with a television (or other display device)
that provides a standard S-video Mini4 input jack. This is the ultimate
display option for the 8-bit Atari. Clarence Dyson has a nice page about
such a project at http://www.wolfpup.net/atarimods/svideo.html .
A "video scaler" or "up-converter" is an adapter that will accept an input
video signal such as RF, composite video, or s-video, and output a conversion
of the signal as a standard VGA video signal. With such a device, the 8-bit
Atari can be used with a standard PC VGA monitor. Examples:
- AV Toolbox manufactures several suitable adapters, listed at:
http://www.avtoolbox.com/upconpage.shtml
- Ambery markets their "Ultra Video to VGA Converter", see:
http://www.ambery.com/vitoxgacoscs.html
and other suitable, more expensive Video to VGA/RGBHV Converter Scalers:
http://www.ambery.com/vitovgcosc.html
- Earlier popular devices included:
- Cheese Video Box from AV Toolbox
- JAM!! from AIMS Lab.
Some people report good results viewing the Atari computer's video signal
through a PC using a TV/video capture card. Wikipedia's article about such
devices: http://en.wikipedia.org/wiki/Video_capture_card
SCART - an acronym for Syndicat des Constructeurs d'Appareils Radiorecepteurs
et Televiseurs - is a 21-pin universal connecting cable/socket system used for
audio/video components in Europe. The cables transmit RGB, composite video,
S-Video, mono and stereo sound. SCART, which is also known as PERITEL, EURO
AV BUS and EUROCONECTOR, is common throughout Europe, particularly in France,
England, Germany, Switzerland, and Scandinavia. SCART is also very popular in
the Russian Audio Video market. It is possible to interface the Atari's
composite video signal, along with the audio signal. DGS sells such a cable,
see: http://www.dgs.clara.net/
Keith Howell has a nice page on some of these topics:

Two current sources for Atari monitor connectivity products:

phono jacks for composite video, chroma, luminance, and mono audio; it also

Subject: 2.2) What is artifacting?
The following is from De Re Atari, Appendix D: "Television Artifacts":
The ANTIC modes with which this can be accomplished are 2, 3, and 15.
ANTIC mode 2 corresponds to BASIC mode 0, ANTIC mode 15 is BASIC mode 8,
and ANTIC mode 3 has no corresponding BASIC mode. Each of these modes has
a pixel resolution of one half color clock by one scan line. They are
generally considered to have one color and two luminances. With the use of
artifacts, pixels of four different colors can be displayed on the screen
in each of these modes.
The term TV artifacts refers to a spot or "pixel" on the screen that
displays a different color than the one assigned to it.
A simple example of artifacts using the ATARI Computer is shown by entering
the following lines:
GRAPHICS 8
COLOR 1
POKE 710,0
PLOT 60,60
PLOT 63,60
These statements will plot two points on a black background; however each
pixel will have a different color.
To understand the cause of these differing colors one must first understand
that all the display information for the television display is contained in
a modulated television signal.
For the rest of the De Re Atari article:
http://www.atariarchives.org/dere/chaptD.php
Software can be designed to take advantage of artifacting to simulate more
colors than are available from the computer in a given graphics mode. The
downside would be that, depending on the video display deviced used, the
actual colors seen are fairly unpredictable, or there may be no artifacting
effect at all.
A classic example of a game that utilizes color artifacting on the Atari is
the Br0derbund game, Choplifter.

Subject: 3.2) What other cassette recorders can I use with my Atari?
Firstly Atari themselves put out several more obscure models beyond the
410/1010/XC11/XC12, generally only known in eastern Europe:
XCA12 Program Recorder -in same case as XC12...Poland
CA12 Program Recorder -in same case as XC12...Poland

Subject: 3.3) How do I run a program from cassette?
To run an Atari BASIC program from cassette:
1. Place the cassette in the recorder.
2. Press REWIND of FORWARD, if necessary, to bring the tape to the position
where the program is located.
3. Boot the computer to the Atari BASIC READY prompt.
4. There are several possibilities for the next step, depending on how the
program was saved, and whether you want to run the program or just load
it into RAM. Enter one of the following four commands:
a. CLOAD loads programs saved with CSAVE
b. LOAD "C:" loads programs saved with SAVE "C:"
c. ENTER "C:" loads programs saved with LIST "C:"
d. RUN "C:" loads&runs programs saved with SAVE "C:"
] Relative efficiency of the three cassette tape recording techniques:
] CSAVE/CLOAD - most efficient - fastest saves/loads - tokenized files
] SAVE "C:"/LOAD "C:" - middle efficiency - middle speed - tokenized files
] LIST "C:"/ENTER "C:" - least efficient - slowest - straight ATASCII
5. The computer will "beep" as a signal for you to press PLAY on the recorder.
6. Press the RETURN key on the computer keyboard, and the program will load
into the computer.
7. Press STOP on the recorder when loading has finished.
8. Unless you entered RUN "C:" above, now enter the command: RUN
To run an Atari BASIC or machine language program from cassette upon
startup:
1. Place the cassette in the recorder
2. Press REWIND of FORWARD, if necessary, to bring the tape to the position
where the program is located.
3. Turn on the computer while holding down the START key.
But if your computer has Atari BASIC built-in and you're running a machine
language program, hold down both the START key and the OPTION key.
4. The computer will "beep" as a signal for you to press PLAY on the recorder.
5. Let go of the START/OPTION button(s).
6. Press the RETURN key on the computer keyboard, and the program will load
into the computer.
7. Press STOP on the recorder when loading is complete and the program is
running.

Stephen Knox writes (12/28/02):
I believe the story on the 815s was Atari didn't want to release them due to
severe QA problems with the drive but they had so many preorders they had to
release something. I think they filled the preorders and then cancelled the
model - Most of them got returned due to problems.
==> Atari 1050 --- a 5.25" floppy disk drive
Same as the 810, plus Dual-Density capability. Two modes of operation:

Rich Mier professes:
You've been plugging and unplugging the SIO cable with the 1050 power pack
plugged in, right? That's a no-no. Most of the time it's Okay, but about 1
in 10, 20 times, it will blow out 'U-1'. It's a CA/LM 3086 I.C. at the right,
rear of the main board. A 14 pin DIL chip. Actually it is an array of 5
transistors.
Unplug the power pack from the 1050, then unplug the SIO cable. Power can be
ON on the CPU. The problem has to do with the secondary winding of the Power
Pack. Remember, the problem only occurs 1 out of 10 - 20 times that you do
it, not all the time.
It doesn't really matter if the 1050 Transformer has power on or off, it
'Might' happen if plugged into the 1050. It is really bad on 810's.
One thing, if the system has been turned off for, oh say, 5 - 10 minutes it
won't matter. By then all the capacitors should be bled(sc?) to 0 volts.

The following information is taken from the documentation for HiassofT's
WriteAtr program, http://www.horus.com/~hias/atari/
Double-Sided drives for the Atari may use one of three different drive-
mapping possibilities.
* Most double-sided Atari disk drives:
First fill tracks 0-39 (or 0-79) on the first side, then switch
over to side 2 and again fill tracks 0-39 (0-79 for 3.5" disks).
* The XF551 first fills track 0 on the first side. Then it
fills track 1, then track 2, ... up to track 39 (on a 5.25" disk)
or 79 (on a 3.5" disk). Then it switches to side 2 and fills
the disk in reverse order (starting at track 39/79, then 38/78,
... til it has reached the end of the disk at track 0).
* The third possibility is the standard in the PC world, but on the Atari
it's possibly unique to drives connected via the Karin Maxi interface.
If your Atari disk drive uses this mapping, it first fills
track 0 on side 1, then track 0 on side 2, then seeks to track 1,
again first fills track 1 / side 1, then track 1 / side 2,
and so on, until it finishes with track 39 (79) / side 2.
The drive switches the heads (sides) first before switching
the track.
Subject: 3.6) What kinds of 5.25" floppy disks can I use with my Atari drives?
Russ Gilbert writes:
If you're talking standard computer store, you can't use those 5 1/4" disks.
I mean you can't use high density disks. They must be double density to use
with the 1050. Almost all double density 5 1/4" disks have a hub ring, high
density disks don't have the hub ring.
RHamiIton5 elaborates: (5/12/01)
The Atari 8 drives do not have write heads and circuity which can handle the
type of oxide coating used on the high density floppy media; they cannot write
reliably to them. The hub ring has just become a sort of marker to distinguish
the high density from the standard double density diskettes.
Way back in your apple days of '79-'82, most disks were hubless and only the
really premium brands offered hubs to prevent slippage and out of round
problems; you could even buy little kits for adding you own hub rings.
When the home computer swell really hit around '83 and price wars began, hub
rings became common on good disks and eventually became standard down to
include most generic bargain diskettes.
The introduction of high density 5.25's required a different coercivity (=
magnetizability) to get more bits in a smaller space and suitable electronics
to do it. These disks were produced hubless; was it a differentiating label or
just unnecessary because of stronger mylar construction? Anyone?
Subject: 3.7) What can I do to extend the life of my floppy disks?
Lee Hart writes (January 2004):
Personally, I have several hundred floppy disks for my Atari 800, Kaypro
4, Heathkit H89, and IMSAI 8080 computers that are 10-20 years old. What
I can say in general:
- Most disks stored in plastic boxes or ziplock baggies survived.
- Most disks stored in cardboard boxes or just their sleeves
did NOT survive.
- Some brands lasted better than others, but I haven't collated the
information so as to make any kind of definitive statements.
- If a disk cannot be read, CLEAN THE DISK DRIVE HEAD before attempting
to read another disk! Otherwise, crap from the bad disk will remain
on the head, and will scar and destroy any SUBSEQUENT disk you put
in the drive! (the voice of painful experience).
- For lack of a better plan, for each of my surviving disks I am:
a. reformatting another blank disk
b. copying the data from an old disk onto the blank disk
Then I have a more recently-produced backup disk in case the
original disk later fails.
Subject: 3.8) What hard drives were designed for my Atari?
Atari never produced hard drives for the 8-bit Atari, but the following
were produced and marketed to Atari users by third parties.
==> Corvus hard drive (5MB, 10MB, or 20MB)
(some Corvus info from an eBay auction by Ben Corr, 7/03)
Attaches via joystick ports 3 & 4 on the Atari 800 only.
-- Corvus Integrator Board - alows access to the Corvus Disc without the
Corvus software, so that any DOS that uses standard SIO calls will work.
-- Corvus Multiplexer - used to network up to 8 Ataris to one Corvus Drive
-- Corvus Mirror card - back up the drive's contents onto video tape
==> SupraDrive Atari Hard Disk, by Supra, later K-Products. 10MB or 20MB.
includes external Hard Disk Interface
Some limitations on drive type and size and total number of drives in sys.
Attaches via PBI, or ECI with adapter.

Such interfaces are covered in other sections of this FAQ List.
Subject: 3.9) How can my Atari utilize my PC's or Mac's storage drives?
==> SIO2PC, by Nick Kennedy
From the SIO2PC home page:
SIO2PC is a hardware & software package interfacing the 8-bit Atari to PC
compatible computers.
The original idea was to have the PC emulate Atari disk drives so Atari
programs could be stored on the PC's hard (or floppy) drives. It turned out
to be quite successful. About 95% of my work was in the software, but a
hardware device to convert logic levels was also necessary. This device is
now commonly referred to as an SIO2PC cable.
Features:
- Emulates 1 to 4 Atari disk drives
- Store your Atari files on PC hard or floppy drives
- Boot from the PC, real drive not needed to start-up
- No software or drivers required for the Atari;
no conflicts: use your favorite DOS
- Twice as fast as an Atari 810 drive and more reliable
- Co-exists with real drives in the Atari daisy chain
- Compatible down to the hardware level: use sector copiers, etc.
- Print-Thru captures Atari print-out and routes to PC's printer
- Convert Atari files to PC files and vice versa

==> Atari Peripheral Emulator (APE), by Steven Tucker
David A. Paterson writes:
"Steven J. Tucker took SIO2PC one better and wrote new software.
The Atari Peripheral Emulator (APE for short):
- lets your PC act as high-speed drives.
- It lets you print to your PC printer.
- And it lets you use your PC modem on the 8-bit."
http://www.atarimax.com/
==> SIO2Linux, by Preston Crow
Pavel Machek made an initial attempt at communicating with the Atari through
an SIO2PC cable using Linux's serial port drivers. He came up with a simple
floppy emulator, femul.c. I rewrote that to add a bunch of features:
* No kernel modules.
Unlike the AtariSIO project, this is just a simple user-space program that
uses a serial port device.
* Create new dynamically sized images
Each image starts as a 3-sector image file, but grows to accomodate the
highest-numbered sector written.
* Mount your native file system as an Atari disk
It's read-only for now, and it doesn't support subdirectories, but each
file is mapped to a different starting sector, and as that sector is read,
it automatically maps in the rest of the file.

==> Sio2OSX, by Mark Grebe
Sio2OSX is a peripheral emulator for the Atari 8-bit computers that allows
the Atari computer to use an OSX based Macintosh as a disk drive, a cassette
drive, and a printer. Sio2OSX peforms functions similar to APE or SIO2PC on
Windows based computers.

Subject: 3.11) How can I use a USB flash drive with my Atari?
USB flash drives are NAND-type flash memory data storage devices integrated
with a USB (universal serial bus) interface. They are typically small,
lightweight, removable and rewritable.
==> SIO2USB, by ABBUC Regional Group Frankfurt / Main
The SIO2USB Interface is a peripheral device that can be attached to an ATARI
8-bit computer using the SIO-Bus. It emulates one or more ATARI Floppy-
Drive(s) and does not require any special drivers or Operating-Systems, it is
fully compatible with all ATARI DOS Systems and extensions. Because the
device is connected to the SIO-Bus, it is not necessary to open or modify the
ATARI. The device is powered by the SIO-Bus and does not need an external
Power Adapter. The data are stored on standard USB Mass Storage Devices (USB
FLASH Drives) as ATARI-Imagefiles (ATR or XFD) on a standard FAT filesystem.
SIO2USB features:
o Can boot an ATARI 8-bit Computer without physical Floppy Drive
o Emulation of up to 3 (virtual) Disk drives simultaneously
o Simple device, attached to SIO-Port, no modification of computer necessary
o Mixed operation of real Floppy and SIO2USB possible
o Fully compatible with all ATARI DOS and OS and all ATARI compatible
extensions

Beyond the above printer models, most any "industry-standard" line printer can
work well with the Atari. For many years, most printers marketed for home use
could be classified into one of two categories: parallel or serial interface.
Parallel line printers were much more commonly used than serial line printers,
with the Epson MX/FX/LX series defining the market.
The most common way to use an industry standard printer with the Atari has
been to attach it through the 15-pin 8-bit parallel port of the Atari 850
Interface Module or equivalent (such as the ICD P:R: Connection). One gotcha
here is that the 850's parallel port is DB15, where the PC world ended-up
standardizing on a DB25 configuration. So you need to find or build a cable,
such as the Atari CX86 Printer Cable, that provides the DB15 connector for the
Atari end, and Centronics-type parallel connector on the printer end, in order
to attach a standard parallel printer to the Atari through an Atari 850 or
equivalent. The pinouts necessary for building such a cable are available
in the Atari 850 Interface section of this FAQ list.
Many 3rd-party disk drives for the Atari (along with the Atari XEP80 Interface
Module) do include a DB25 parallel printer port, rendering the need for an
Atari-specific printer cable unnecessary.
The Atari 850 Interface Module and equivalents also provide standard DB9
serial RS-232-C ports, permitting use of standard serial line printers with
the Atari. But this is much less common than parallel, both in the Atari
world and in the industry at large.
Some folks have connected more modern inkjet and laser printers with parallel
connections to the 8-bit Atari with success. Graphics printouts from the
Atari may be less than ideal (look for a printer with an Epson MX/FX/LX
printer series emulation mode), but these types of printers should work fine
for plain text output if they can handle simple line print jobs.

I use HP LaserJet 4Ps on my Ataris. They are one of the last front panel

the interface, not impossible, but not as easy as selecting on the panel.
This does allow you to print just about any point size of the internal
fonts in the printer on your Atari.
Either way, you really have to do a little work to get properly formatted
output from a word processor. I have managed to use the proportional font

==> SIO2PC, by Nick Kennedy
From the SIO2PC home page:
SIO2PC is a hardware & software package interfacing the 8-bit Atari to PC
compatible computers.
The original idea was to have the PC emulate Atari disk drives so Atari
programs could be stored on the PC's hard (or floppy) drives. It turned out
to be quite successful. About 95% of my work was in the software, but a
hardware device to convert logic levels was also necessary. This device is
now commonly referred to as an SIO2PC cable.
Features:
- Emulates 1 to 4 Atari disk drives
- Store your Atari files on PC hard or floppy drives
- Boot from the PC, real drive not needed to start-up
- No software or drivers required for the Atari;
no conflicts: use your favorite DOS
- Twice as fast as an Atari 810 drive and more reliable
- Co-exists with real drives in the Atari daisy chain
- Compatible down to the hardware level: use sector copiers, etc.
- Print-Thru captures Atari print-out and routes to PC's printer
- Convert Atari files to PC files and vice versa

Beyond the above modem models, most any "industry-standard" external serial
modem can work well with the Atari. These have been commonly sold for PCs for
many years. The Hayes Smartmodem more or less defined the market for these,
initially.
One common way to use an industry standard external serial modem with the
Atari is to connect it to the SIO port via an Advanced Interface Devices
(A.I.D., later Supra) R-Verter Serial Bus Modem Adapter cable, or
equivalent.
The other common way to use an industry standard external serial modem with
the Atari is to attach it through the 9-pin RS-232-C serial port of the Atari
850 Interface Module or equivalent (such as the ICD P:R: Connection). One
gotcha here is that the serial port on the 850 is DB9 female, where the PC
world ended up standardizing on a DB9 male connector for this purpose. But
gender converters are readily available.
For using modems at speeds of 2400 bps and up with the Atari, it will be
useful to have an understanding of data flow control. Here is a definition
of flow control from www.modems.com:
Often, one modem in a connection is capable of sending data much faster than
the other can receive. Flow control allows the receiving modem to tell the
other to pause while it catches up. Flow control exists as either software,
or XON/XOFF, flow control, or hardware (RTS/CTS) flow control. With software
flow control, when a modem needs to tell the other to pause, it sends a
certain character, usually Control-S. When it is ready to resume, it sends a
different character, such as Control-Q. Software flow control's only
advantage is that it can use a serial cable with only three wires. Since
software flow control regulates transmissions by sending certain characters,
line noise could generate the character commanding a pause, thus hanging the
transfer until the proper character (such as Control-Q) is sent. Also,
binary files must never be sent using software flow control, as binary files
can contain the control characters. Hardware, or RTS/CTS, flow control uses
wires in the modem cable or, in the case of internal modems, hardware in the
modem. This is faster and much more reliable than software flow control.
Some 2400 bps modems, and probably all modems with 9600 bps speed capabilities
and up, normally use V.42 standard error correction and V.42bis standard data
compression. But V.42 requires either software or hardware flow control, and
V.42bis requires hardware flow control (and V.42 error correction).
Hardware flow control is not available with the Atari 850 serial ports.
As a result, just before dialing out with your Atari telecom software, it's
usually desirable, if not necessary, to disable your modem's flow control.
The Hayes modem command to disable flow control looks like:
AT&K0
The top speed of the Atari 850 serial ports is 9600 bps.
Clay Halliwell offers a tip on utilizing 9600 bps through the 850 Interface:
On 11 Feb 1996, Marc G. Frank said:
> I'm having problems getting a modem attached to my Atari 850 to
> communicate at 9600 baud. When I set my communications program to 2400
> baud, everything works fine. However, when I set it to 9600 baud, the

The problem with the 850 is that some of them (like mine) don't produce a
PERFECT 9600 baud signal. As a result modems can't train on it, and while
they will echo characters back, for some nitpicky reason they won't pick up
on the "AT" attention code.
The solution is to do all your dialing at 2400 baud, but set the S37
register to force the modem to try to connect at 9600. Then switch your
Atari to 9600 after connecting.
Through the use of an ICD MIO or a CSS Black Box, it is possible to utilize
modems at speeds up to 14.4 Kbps (V.32bis) at full speed with no loss of data.
The serial R: device handler for the Black Box supports hardware flow control
natively. Optional for the Black Box, but essential for the MIO, is the
HyperSpeed handler by Len Spencer.

Modern external modems designed for "modern" PCs now normally utilize a USB
connector rather than the older standard DB9 RS-232-C serial connector.

==> CSS Multiplexer ("MUX")
Description from the CSS online catalog:
The Multiplexer is a collection of cartridge interface boards that allow up to
8 Ataris to read and write to the same drives (typically a hard disk), access
the same printer(s), and talk to each other. It is the first practical
networking system for the Atari 8-bit computer.
One "master" computer (any 8-bit) is equipped with the master Multiplexer
interface. Then up to 8 "slave" computers hook up to this master, each having
their own slave interface. The slave interface consists of a cartridge that
plugs into the cartridge port. It has its own socket on the top so you can
use whatever cartridges you desire with the system.
The "common" peripherals (things that are to be shared) are connected to the
master. On each slave, all disk and printer I/O is routed through the master
so no extra disk drives are needed. The master computer can be configured in
any manner you wish. You may have certain peripherals local to the slave or
routed to a different number on the master. Note that serial ports (R: RS-232
interfaces) are not multiplexed. All slaves are independent and do not need
to have the same program running on them.

==> GameLink and GameLink II
This text by Andreas Koch:
In the late 80`s and early 90`s Chuck Steinman and Jeff Potter ("The ADGA
Group") developed some networking-computer-hardware to link two or more Ataris
together, so that multiplayer games are possible, where each user has its own
computer and tv/monitor screen. The hardware was/is computer independant and
will run fine on any Atari 8Bit computer (whereas most software for it will
only work on XL/XE computers). During a 3-4 year period of development two
different hardware add-ons were developed:
a) Gamelink-1: This hardware was developed in 1989/90. It links two
computers together via the joystick ports. It is limited to a maximum
of 2 computers and thus 2 or 6 players, meaning one free port per
XL/XE computer and 3 free ports per 400/800 computer. However, the
few existing games for this hardware merely support 2 players, no
matter, which computer you have...
b) Gamelink-2: This hardware was developed in 1991/92. It links 2 to 8
computers together via the SIO-port. One computer will then act as
the master and has to boot up the software (from tape, disk, harddisk,
etc.) first. Then all other "slave" computers connect to it and boot
off of this master computer (one after another of course). In Europe
we call this device "Multilink", mostly because of the games written
by Bewesoft (Jiri Bernasek) called Multi-Dash, Multi-Race, Multi-Worms.
A two-computer link-network can easily be done with one SIO cable, just
open the end of the SIO cable and exchange cables number 3 and 5. You
now have an easy two-computer (2-4 players) network-cable.
For some available software, that supports this networking-computer
hardware, see 8.16 which programs support networking computer hardware...
Subject: 5.5) How can I connect my Atari to a high-speed/Ethernet network?
Marius Diepenhorst has pioneered the following technique. He writes (2004):
"Try to get a LANTRONIX UDS-10 device. It acts like a modem but it is a LAN
-> RS-232 converter. So with that device you can have incoming and outgoing
'calls' like modem ones via the internet.
I ran my Atari 8bit bbs with such a thing. The Lantronix MSS-10 or MSS-100
will do too. But in that case you have to make a custom RS-232 cable (easy
job).
More info www.lantronix.com

It is REALLY a cool thing. Not only for you, but for more atari fans I guess."
Other, similar serial-to-Ethernet interfaces from Lantronix have been
successfully utilitized, including the MSS100:
www.lantronix.com/device-networking/external-device-servers/mss100.html
as well as the discontinued MSS1-T.
Note that the UDS-10 lacks DNS support, while the MSS100 and MSS1-T include
DNS support.
Subject: 6.1) What is the Atari 850 Interface Module?
While the Atari's SIO and controller ports did not conform to established
industry standards, Atari produced the 850 Interface Module to address this
issue. The 850 connects to the SIO port on the Atari, and provides:
- Four 9-pin RS-232-C serial ports
- One 15-pin Centronics-type parallel Printer Port
Many "industry standard" (of the time) printers, modems, and various other
devices can be used with the Atari computer in combination with an 850
Interface Module. Also, Atari's own 825 printer and 830 modem are connected
to the computer via the 850 Interface Module.
RS-232-C is a technical standard of the Electronic Industries Association
(EIA). Published in August of 1969, it is titled "Interface Between Data
Terminal Equipment and Data Communication Equipment Employing Serial Binary
Data Interchange." The standard specifies electrical signal characteristics
and names and defines the functions of the signal and control lines which make
up a standard interface, called RS-232-C.
The 850 should be thought of as an RS-232-C "data terminal" (DTE, or Data
Terminal Equipment).
The 850's RS-232-C serial ports support the following baud rates:
45.5 bps*, 50 bps*, 56.875 bps*, 75 bps**, 110 bps, 134.5 bps, 150 bps,
300 bps, 600 bps, 1200 bps, 1800 bps, 2400 bps, 4800 bps, 9600 bps
* These Baud rates are useful for communications with Baudot teletypes, for
RTTY (radioteletype) applications. They are more commonly referred to as
60, 67, and 75 words per minute.
** This Baud rate is sometimes used for ASCII communications, and may also
be used for 5-bit Baudot RTTY. The latter is commonly referred to as
100 wpm.
While the Atari Operating System includes the necessary Printer Port software
handler, the RS-232 serial port handler is loaded into the computer's RAM via
a "Power-On Bootstrapping Operation" as follows:
Bootstrapping Operation Without Disk Drive:
When the Atari computer is turned on, it issues a disk request via SIO. If no
Drive 1 is present with power ON, the 850 responds to the disk request. The
computer then loads the bootstrapping program from the 850, as if it were
reading from a disk. The bootstrapping program is then run, and it gets the
RS-232-C handler from the 850 and relocates it into the computer's RAM. The
memory occupied by the bootstrapping program is then freed (but the handler
remains).
Bootstrapping Operation With Disk Drive:
If there is a disk drive attached to the system (Drive 1 only), it responds to
the disk request issued by the computer at power-on. The computer then reads
a start-up program from that disk, such as a DOS. The 850 does not respond to
the disk request if a disk drive responds first; therefore, the program loaded
from disk must load the handler from the 850. Many varieties of DOS for the
Atari include an explicit provision for loading and executing the
bootstrapping program from the 850, such as through the use of an AUTORUN.SYS
file. When the 850 bootstrapping program is executed, it gets the RS-232-C
handler from the 850 and relocates it into the computer's RAM. The memory
occupied by the bootstrapping program is then freed (but the handler remains).

Very early 850's are in an all-black brushed steel case, but most are in a
beige plastic case matching the 400/800 computers.
Because the 850 was relatively expensive, provided more capabilities than the
average user was looking for, and was at times unavailable from Atari despite
high demand, there were many 3rd-party interfaces designed to provide some
compatible subset of the 850's features. Perhaps the most prominent example
of such a product is the P:R: Connection from ICD.
Subject: 6.2) What is the Atari XEP80 Interface Module?
This text written by Thomas Raukamp.
Since the development of the Atari 8-bit line of computers in 1979, users
wanted better text displays than the default 40x24. There has been some
attempts to satisfy this need, like the Austin-Franklin board or the Ace
80/80xl cartridge. For more informations about these modifications read The
Atari 8-bit Hardware Upgrade FAQ from David A. Paterson.
The Atari XEP80 Interface Module is Atari's entry to the 80 column field. It
lets a XL, XE, 400 or 800 computer system display a full 80 columns across
your monitor screen. The XEP80 provides a 256-character wide by 25-line
display window. Up to 80 characters are displayed horizontally at once, and
you can scroll horizontally all the way to the 256th character, depending on
the application you're running. The XEP80 is connected to your system via a
joystick port.
The XEP80 Module interprets commands from the computer for screen display or
output to a printer. The module is supplied with an industry-standard 8-bit
parallel port so you can connect a parallel printer to your Atari 8-bit (I
even use a HP LaserJet IV on my 130XE ;) ).
All programs that use the standard screen call (E:) should be compatible with
the XEP80 Module. The software provided by Atari supports a 320x200 graphics
mode - this mode only support direct bit images. Note that you can't use all
of the standard graphic capabilities of the Atari anymore.
Although Atari recommends a monochrome monitor for usage with the XEP80, it
runs fine with any type of composite monitor. The output looks great on my
Commodore 1084 for example.
Along with the module comes a software-package containing an AUTORUN.SYS file,
which is the XEP80 handler. If you want to use the module with an application
that is compatible with the XEP80, which has it's own AUTORUN.SYS file, you
can append the application's AUTORUN.SYS on the module's AUTORUN.SYS.

Subject: 6.3) How can I use a SCSI/SASI device with my Atari?
SCSI background from http://www.ioiscsi.com/library/library_scsi.html
and http://www.techweb.com/encyclopedia/defineterm.jhtml?term=scsi
SCSI - Small Computer Systems Interface. Pronounced "scuzzy."
SCSI is an ANSI standard for connection peripherals/devices to your computer
via a hardware interface, which uses standard SCSI commands.
In the early 1980's, Adaptec's founders, while at disk drive manufacturer
Shugart Associates, developed a parallel I/O interface called SASI for Shugart
Associated System Interface. When this specification was finalized, it was
released to several different manufacturers and enjoyed commercial success.
In 1982, SASI was presented to ANSI as a basis for standard. Because of the
commercial success and widespread market use of SASI, ANSI formalized and
extended the SASI specification and changed the name to SCSI (in part to
separate the specification from any one vendor in particular). In June 1986,
SCSI was formally adopted by ANSI.
The following hardware interface devices allow SASI/SCSI devices (such as hard
disk drives) to be connected to the Atari:
==> ICD Multi I/O (MIO)
- Parallel printer interface
- Serial interface, for modem or serial printer. will handle 19.2Kbps
- 256K or 1 MB RAM, for RAMdisk or printer spooler
- SASI/SCSI interface, supports up to 8 controllers.
- Limited to drives with 256-byte sectors.
Attaches via PBI, or ECI with adapter.

Subject: 6.4) How can I use an IDE device with my Atari?
IDE background from TechWeb,
http://www.techweb.com/encyclopedia/defineterm.jhtml?term=ide
IDE - Integrated Drive Electronics
IDE is a type of hardware interface widely used to connect hard disks, CD-ROMs
and tape drives to a PC. IDE was always the more economical interface,
compared to SCSI.
With IDE, the controller electronics are built into the drive itself,
requiring a simple circuit in the PC for connection. IDE drives were attached
to earlier PCs using an IDE host adapter card. Today, two Enhanced IDE (EIDE)
sockets are built onto the motherboard, and each socket connects up to two
drives via a 40-pin ribbon cable for CD-ROMs and similar devices and an 80-
wire cable for fast hard disks.
IDE drives are configured as master and slave. Jumper pins on the drive
itself are used to set up the first drive on the cable as master and the
second one, if present, as a slave.
The IDE interface is officially known as the ATA (AT Attachment)
specification. ATAPI (ATA Packet Interface) defines the IDE standard for CD-
ROMs and tape drives. ATA-2 (Fast ATA) defined the faster transfer rates used
in Enhanced IDE (EIDE).
The following hardware interface devices allow IDE devices (such as hard disk
drives) to be connected to the Atari:

==> KMK/JZ IDE Hard Drive Interface
by Jacek Zuk and Konrad Kokoszkiewicz (Draco)
KMK writes (March 2005):
This is sort of cartridge fitting in ECI+CARTRIDGE slot in XE computers.
The box is about 1,5 cm high, 15 cm long, and its width is less or more
equal to the XE ECI+CARTRIDGE slot. You have an ECI+CARTRIDGE connector
at one end, and an IDE cable at the other end. The whole is cased with
black plastic case.
What advantage does it have over similar products?
1) it is available and still being made;
2) the software is maintained, you can download an upgrade for the
internal handler, for example;
3) it uses a well defined Atari parallel bus interface, thus no OS
modifications or other hacks are necessary to get the machine booting
from this device;
4) it works fine with unmodified SpartaDOS X, SpartaDOS 3.x, MyDOS (and
other DOS-es, but using it with DOS 2.x lacks sense);
5) it allows you to make true partitions (up to 16);
6) it can currently address up to 8 GB (and this is not a hardware
limit, so an upgraded internal ROM can do more);
7) it works with all devices which are ATA-compliant;
8) you can use two drives (master/slave);
The Interface's internal software provides two modes: native and emulation.
The native mode uses a 512 byte physical block as a logical data sector, the
emulation mode uses the physical block to store two 256 byte logical data
sectors. ALL existing DOSes require the emulation mode to work properly.
Maximum drive capacity: 8388607 physical blocks on each device.
Maximum number of partitions: 16
Maximum capacity of a partition: 8388607 logical sectors
Logical sector length: 256 or 512 bytes
Average speed: 58 kilobytes per second (native mode, R/W)
32 kilobytes per second (emulation mode, reading)
7 kilobytes per second (emulation mode, writing)
Booting from any partition
Write protection capability
8 jumpers to set the device number for the operating system
Note, that ALL existing DOSes limit the partition size to 16 MB.

USB - Universal Serial Bus
A hardware interface for low-speed peripherals such as the keyboard, mouse,
joystick, scanner, printer and telephony devices. USB has a maximum bandwidth
of 12 Mbits/sec (equivalent to 1.5 Mbytes/sec), and up to 127 devices can be
attached.
USB ports began to appear on PCs in 1997. It has now esentially replaced the
older RS-232 serial and Centronics-type parallel ports on modern PCs, and USB
has become the primary means for connecting most external devices to today's
computers.
The following project aims to provide USB compatability to the Atari:

Subject: 6.7) What are the power requirements for my Atari components?
The household mains electricity supply is an alternating current (AC) that can
be described with two parameters: the voltage (in volts) and the frequency
(in Hz).
In North America, the standard household wall outlet offers 120 V/60 Hz power.
In much of the rest of the world, the mains is now standardizing to
230 V/50 Hz. In the time of 8-bit Atari computers, most of continental Europe
used 220 V/50 Hz, and the UK used 240 V/50 Hz.
In any case, the household alternating current must be converted to a
direct current (DC) for use by electrical devices such as Atari computers
and peripherals.
In some cases, the entire conversion is done via an external "power supply"
that sits between the wall outlet and the electrical device. Such power
supplies both transform the household power to a lower voltage, and they
also rectify the current from AC to DC.
In some cases, the external "power supply" is simply a transformer that lowers
the household voltage. The lowered AC voltage is rectified to DC inside the
device.
In some cases, both the transformer and the rectifier are located inside the
computer or peripheral itself. The device plugs directly into the wall
outlet, with no external "power supply" needed.
The INPUT of an external power supply will indicate:
1) Input voltage in units of volts (110V for N.Am., 220V Euro, 240V UK)
2) Input frequency in units of hertz (60Hz for N.Am., 50Hz Euro)
The OUTPUT of an external power supply will indicate:
1) Output Voltage, in units of volts (V)
2) Whether the output voltage is AC or DC
3) one or sometimes both of:
- Output Current, in units of amperes ("amps") (A) or milliamps (mA)
- Output Power, in units of volt-amperes ("volt-amps")(VA) or watts (W)
An external power supply may also indicate a peak power rating. The power
rating is the highest amount of power the unit can supply, according to the
manufacturer, but this is only for a very brief time. The power rating may be
indicated in units of volt-amperes (VA) or in units of watts (W). The power
supplies themselves usually indicate this rating near the "Input" label (in
order to distinguish this rating from the sustained power output.) The
power ratings for Atari power supplies are given below as "Max:"
Higher-than-specified power and current capacities are entirely usable, and
often preferable because such supplies run cooler and last longer.
In practice the power units VA and W are used interchangeably, even though
they are not identical.
Direct Current (DC):
Power (in watts) = current (in amps) * voltage (in volts)
Alternating Current (AC):
Apparent Power (in voltamps) = current (in amps) * voltage (in volts)
Effective/True Power (in watts) = current (in amps) * voltage (in volts)
* cosine(phase, or angle of lag)
cosine(phase) is known as the "power factor"

What happens if power supplies for the Atari 1050 and Indus GT are mixed?
Paul Alhart writes (20 Jan 2004):
"The Indus requires DC, the 1050 uses AC. Plug an Indus
supply into a 1050 and it will usually blow the rectifier diodes in the
1050. Plug an Atari supply into an Indus and it will blow the fuse in
the supply. It can damage the mother board as well."
Multi I/O (MIO), all versions, can use both AC and DC supplies, BUT:
stick to voltages of at least 6.2-7.2 V.
On 2003.09.01 James Bradford wrote: "Doesn't matter what polarity the
centre is, the MIO has a fullwave bridge rectifer in it.
AC would be better because the diodes would be used half the time."

Subject: 6.9) What preventative maintenance can I do on my Atari system?
This new section could use more contributions! For starters, Russ Gilbert
writes (2004.11.05):
The main suggestion I have is to use your A8s. This keeps the keyboard
working. I didn't have a problem with my 800XLs, but my 1200XLs required
typing the keys a bunch to get them to respond to every keypress. USE YOUR
A8s.
The problem, I suspect, is oxidation of contacts, in the keyboard, at the
cartridge slot, maybe the SIO port. Use of a soft eraser on cart edge
connector is one thing I think helps.
I would guess one could take the 1200XL keyboard apart and clean the mylar
traces with ??? 90% isopropyl alcohol and a Q-Tip. I still have my
original 800XL, it has copper switches in the keyboard, no mylar. I don't
know what my 800s have in the keyboard, but I would guess copper switches.
My original 800XL has all socketed chips also.
Subject: 6.10) What graphic tablets were produced for the Atari?
This section by Andreas Koch.
- Atari Touch Tablet by Atari (came with Atari Artist cart., Micro
Illustrator compatible),
- Koala Pad by Koala Industries (came with Koala/Micro Illustrator
cart.);
- Powerpad by Chalkboard Inc. (came without software!); the following
carts were available separately for the Powerpad: Micro Illustrator,
Leo's Lectric, Micro Maestro, The Programmers Kit, Logic Games, Bear
Jam (as refered to Antic, September 1984);
- Animation Station by Suncom (came with Micro-Illustrator cart.);
Subject: 6.11) What lightpens were produced for the Atari?
This section by Andreas Koch.
- Atari Lightpen (came with Atari Graphics cart.; it produces pictures
with 127 sectors in length, thus not Micro-Painter, nor Micro-
Illustrator compatible; however appropriate converter programs can be
found in the public domain, e.g. the Rapid Graphics Converter);
- Edumate Lightpen (came with a disk with 6 Basic programs; a program
called Peripheral Vision was available separately from Future House);
- Tech-Sketch-Lightpen (came in two versions: a) the cheaper version
which included a disk with Basic programs only and b) the more expensive
version which included the disk with Basic programs and the Micro-
Illustrator cartridge);
- MC-Pen-Lightpen (came with a disk with 4 Basic programs);
- Reston Lightpen (came with ???);
Note: these infos were taken from Antic, September 1984; I am not sure,
if all these items were really available as listed...
Subject: 6.12) What lightguns were produced for the Atari?
This section by Andreas Koch.
- Atari XG-1 Lightgun (came in two versions: a) complete with XEGS,
keyboard, joystick, power supply, tv-cable, Lightgun, FS II cart and
Bug Hunt cart all in one package and b) in a separate package,
containing the Lightgun and the Bug Hunt cartridge); thats's why Bug
Hunt does not have its own package, it was always included with the
Lightgun package and/or the complete XEGS package...
- BEST Lightgun by Best Electronics (a sort of selfmade (?) Lightgun);
- Sega-Lightgun (normally not Atari compatible; but can be converted
into an Atari compatible lightgun easily);
- other lightguns (most of these have to be converted)...
Note: After having 3-4 Atari and at least one (converted) Sega lightgun,
it is my personal impression, that the Atari lightgun merely works ok
on/with TV-sets (and not at all with a monitor), whereas the Sega lightgun
works alright on TV's and (most) monitors. Since I never had a Best
lightgun I cannot comment on this one... (Andreas Koch);
Subject: 6.13) What paddles were produced for the Atari?
This section by Andreas Koch.
- Atari Paddles (usually a pair of Paddles);
- Telegames Paddles (available as a) a single paddle and b) a pair
of paddles);
- Reston Paddles (available as a) a single paddle and b) a pair
of paddles);
- and many others...
Note: Both single and duo (pair) paddles are compatible to each other,
using only one port-connector (only one joystick port). Thus, with a pair
of paddles you can connect up to 4 paddles (2 pairs) to the XL/XE models
and up to 8 paddles (4 pairs) to the Atari 400/800 models.
Subject: 6.14) What voice/sound synthesis hardware was produced for the
Atari?
This section by Andreas Koch.
- Voice-Box II by The Alien Group (a software and hardware package);
- 1400XL/1450XLD Voice Synthesizer (built-in chip inside the extreme rare
Atari 1400XL/1450XLD models);
- Talk is Cheap by Ed Stewart, Antic Volume 2 Number 4, July 1983,
pages 64-66; hardware schematics only (a test/demo program is
mentioned in the text, but not printed in the magazine!);
- Cheap-Talk by Lee Brilliant, Analog Computing, issue 29, April 1985,
pages 59-67; hardware schematics and software demos, for example
"First Words");
- many other voice synthesizers (mostly selfmade and based on a chip by
National Semi Conductor);
Subject: 6.15) What sound-digitizers/samplers were produced for the Atari?
This section by Andreas Koch.
- Parrot (2-Bit) by Alpha Systems, Anthony Ramos;
- Parrot-2 (2-Bit or 4-Bit?) by Alpha Systems, Anthony Ramos;
- 2-Bit Replay (2-Bit) by 2Bit-Systems Ltd.
- Sound N'Sampler (2-Bit) by Ralf David;
- Sound Digitiser (2-Bit) by Ralf David;
- Sound-Meister (2-Bit) by Irata;
- Sound-Digitizer (2-Bit) by Irata;
- Digitales Mikrofon (2-Bit) by Compy-Shop;
- Voice-Master (2-Bit) by Covox Inc.;
- Analog-Sample-Processor (2-Bit) by Steven Lashower (Analog Magazine);
- Atari-Sound-Sampler (2-Bit) by Andreas Binner and Harald Schoenfeld
(german Atari magazin 1/1989, pages 44-49, complete with schematics,
documentation, sample-program and assembler-source);
- Alphasys-Sound-Sampler cart. (4-Bit) by ANG/Mirage (released as a mono
version; a stereo (two Pokeys!) version was promised/planned, but afaik
never released);
- ARGS-XE-Sampler (8-Bit) by ABBUC regional group ARGS (only one or
two prototypes exist, alas the hardware was never released due to lack
of (sampling/digitizing) software; maybe a good idea for the hardware
and software experts out there!);
- and many others ...
Subject: 6.16) What sound-enhancement upgrades were produced for the Atari?
This section by Andreas Koch. POPS info updated 8/15/06 by mdc.
a) enhancements for 2- or 3-channel sound:
- POPS, polyphonic-pokey-sound by Lee Brilliant (3-channel support with one
Pokey!); refer to Analog Computing, issue 66, november 1988, pages
54-60; only 1-2 programs exist for this mod., see: 8.14 stereo-software
for the Atari;
Lee Brilliant writes: (2006.08.09)
In reality, the POPS device was only a set of connections to the Atari.
The internal circuitry (Simple to build) was used ONLY to control the
volume of the sound and to add amplification to power speakers. One
could do without the amplifiers if they have their own. But the POPs
did not give just two channel sound, it gave _three_. My design
allowed for left, center, and right amplifiers and speakers. It always
caused a stir at Atari conventions and user groups. The software I used
with it was POKEY Player which was commonly available then. One had to
get that separately and then modify it slightly to drive the three
channels separately. At the time there was a lot of support for that
program and lots of music for it.
- stereo with two Ataris (and thus 2 Pokey chips); use computer/pokey 1
for the left channel and computer/pokey 2 for the right; no special
hardware required for this trick (but specially programmed software!);
see also: 8.14 stereo-software for the Atari;
- stereo with 2 Pokey chips (in one Atari!); refer to an article written
by Chuck Steinman (which probably appeared in Atari classic?) on how
to upgrade your Atari internally with a second Pokey chip; or ask
Freddy Offenga for a deluxe-stereo-version, that uses a PCB instead of
the piggy-back method. For a list of software that supports this mod.
see also: 8.14 stereo-software for the Atari;
- Stereo-Blaster and Stereo-Phaser by Portronic/AMC-Verlag, these were
hardware add-ons that connected via the monitor port to the Atari and
gave you "another" monitor port and 2 cinch connectors to connect to
the monitor and/or the hifi-system; various small paddles (4-10,
depending on the model you have) make it possible to change amplitudes,
frequencies, etc. and thus generate a "pseudo-stereo" sound. These
add-ons also amplified the sound and thus made quality recordings of
Atari sounds much easier. Alas, these hardware add-ons were quite
expensive and thus not many (less than 100) were sold. Therefore no
special software is required, every A8 sound can be changed or
enhanced to "simulated-stereo"...
- Stereo-Blaster-Pro, a hardware add-on by Portronic/AMC-Verlag similar
to Stereo-Blaster and Stereo-Phaser, but programmable! This add-on had
only 1 small paddle, to amplify the sound-volume; the stereo-sound
could be generated via two simple Poke-Statements, a demo-disk therefore
was included. Alas, not many items were sold and afaik no-one else
programmed stereo-software for it. See also: 8.14 stereo-software for
the Atari...
b) other sound enhancements:
- Covox-Sound-Enhancement, originally developed in Poland; with some
electronic parts and pieces you can upgrade your Pokey's abilities, to
playback any digitised/sampled sound with 8-Bit resolution, instead of
its usual 4-Bit digi/sample playback resolution (see also 8.14).
- SID-upgrade, the SID is the standard sound-chip in the C64 computers.
Some polish freaks/nerds have found a way to include it into an A8,
but allthough I have seen quite a lot of pictures (for example at
atariarea.nostalgia.pl) with this mod. and already found 1 or 2
programs that detect it (for example System Info 2.x by Draco), I
have not yet found any schematics for this upgrade. Anyway, it exists,
and with some programming skills it would surely be possible to write
programs then, that playback SID sounds on those Ataris which have this
upgrade installed...
- AMY sound-chip, the AMY sound-chip was originally produced by
Atari and installed into the 65XEM computer. Alas, it was never
available to the public and only very few prototypes of this 65XEM
(maybe less than 10?) do exist. Besides of that RUMOURS say, that
Atari had quite some problems with this soundchip and never finished
it completely/successfully. If the rumours are true, then this
soundchip provided many more sound channels, more octaves and even
more and better sound power than two Pokeys together (for more infos
take a look at this URL: )
- guess there are dozens of other sound enhancements, for example sound
cards (like Adlib, etc.), sound-chips, midi-interfaces, etc. that could
be attached or converted to the A8; I won't name them all here...(A.M.)
Subject: 6.17) What MIDI enhancements are there for the Atari?
This section by Andreas Koch and Mathy van Nisselroy.
Midi is standard on the Atari ST computers, because it is built-in into
these computers. Nevertheless, Midi was long before the arrival of the
ST computers on the market and thus, it is no surprise that there are
even midi-interfaces and enhancements for the classic 8Bit Ataris. The
following "types" do exist:
- "Midi-Mate" and "Midi-Track" by Hybrid Arts (USA), comes with hardware
+ software, see reviews & tests in Antic, Analog and other magazines.
MidiTrack requires 48k RAM, MidiTrack II 64k RAM and MidiTrack III
128k RAM (XE compatible, not Axlon compatible). MidiMate features
MIDI IN+OUT and SYNC IN+OUT ports, but lacks a second SIO port.
MMS (MIDI Music System) is a MIDI version of AMS, also sold by Hybrid
Arts and comes with AMS to MMS converter software...
- "MIDI Master" by 2-Bit Software (UK), comes with hardware+software.
Features MIDI IN+OUT ports, an extra SIO port, but no SYNC ports.
See also reviews and ads in (New) Atari User...
- "MIDI interface" by DIGICOMM (UK), comes with hardware + 'example
programs'. Features MIDI IN, THRU and OUT ports. There`s no word
about a second SIO port or any SYNC ports. See also reviews and ads
in (New) Atari User...
- "MIDIMAX" by Wizztronics (UK), comes with hardware and software.
Features MIDI IN+OUT ports and a second SIO port. The MMS software
that comes with MidiMax requires 48k RAM and is fully compatible to
the Hybrid Arts hardware+software. This means, one can use the
software with both Midi-interfaces or use the interfaces with the
software of both vendors...
- "Atari-Midi-Interface" by Karlheinz Metscher (appeared in the german
magazine Computer Kontakt June/July 1986, pages 69-75, complete with
documentation, schematics and its first program "Midi-Receiver";
in Computer Kontakt October/November 1986 appeared the second program,
called "Midi-Disk" - a Midi Recorder and Player program);
- "Midi-Interface for Atari XL/XE" by Ireneusz Kuczek (appeared in the
german ABBUC magazine, issue 65, pages 3-6); the paper-mag. includes
a schematic for the midi-interface and some translated descriptions for
the software (translated from polish to german language), whereas the
disk-magazine contains the midi-programs "Midiplay Version 1.3" by I.
Kuczek, "Midi-Recorder Version 1.2" by I.Kuczek, "Rec to Mid" by I.
Kuczek (a converter program for the IBM-PC!), "Midi-Sequencer V.1.15"
by Maciej Sygit and "Midi-Pattern-Editor MPE V.2.3" by Radek Sterba.
These programs and many additional demo sounds are also available in
the ABBUC PD library (PD numbers 625-632).
- guess there are several other (selfmade) midi-interfaces for the Atari
8Bit available, alas they also require a keyboard or synthesizer and
self-created (or downloaded) midi-sounds can only be played back via
such a midi-interface and the affore mentioned keyboard/synthesizer.
As of yet, it seems there exists no midi-player program, that can
playback any midi-sound via the Atari Pokey chip, nor any converter
program, which can convert *.MID sounds into other Atari sound formats
(that could be played back on the Atari then)...
Subject: 6.18) What graphics enhancements are there for the Atari?
This section by Andreas Koch.
- some 80 column interfaces made by Atari and third parties. Allthough
these interfaces are there to provide a better text display with 80
chars. per line, they can somehow be used as a simple graphic
enhancement; think I have seen a graphic demo for the XEP-80 device
somewhere, that used a higher graphic resolution in Gr. 0 or Gr. 8
and also provided some animation (not only text, but also graphics),
alas I don`t remember the name of that demo...;
- the ultra-rare 1090XL box and probably graphic cards for it (who-ever
owns this item, doesn't use it, who-ever would like to have + use it,
doesn't own it or cannot afford it!);
- more seriously: Antic and GTIA upgrade by Chuck Steinman. Afaik, an
article about that topic appeared in Atari Classic, since I do not own
it, I can merely speculate that it adds a second Antic and GTIA for
higher resolution and/or more colours...;
- many selfmade upgrades, using graphic chips or graphic cards from other
computers...
Subject: 6.19) What types of memory upgrades are there for the Atari?
This section by Andreas Koch.
Just a short overview here, for a more detailed description (table), see
also 8.10 kinds of atari ramdisks (and 8.11 + 8.12 for programs that
support or require a ramdisk). The following memory enhancements do exist:
- Atari 400/800: ramdisks on memory boards, that fit into the normal
Atari 800 memory slots (Axlon and Mosaic types);
- Atari XL/XE: a) internal memory enhancements:
- piggy-back versions,
- professionel PCB versions,
- SIMM-module versions;
b) external memory enhancements:
- via XL-Parallel-Bus,
- via XE-Cart.port+ECI,
- Flash-ROM cart. versions,
- other Cartridge versions,
- RAM-Card versions,
- SIO-cartridge versions,
- ...
Note that many of these XL/XE memory enhancements are just hobbyist or
selfmade-projects. Most versions which use newer PC technologies
(Flash-ROM cart., RAM-Card, SIO-cart., etc.) are still under development!

400/800 rev.B NTSC Information from a ROM dump and the rev.B source
listing. The part numbers were listed in the
catalog from 'Best Electronics'. According to
'Mapping the Atari' rev.B ROMs have a 'B' at the
end of the part number, therefore I figure these
part numbers are from rev.B.
400/800 rev.B PAL Could exist, since the NTSC version exists and
there's some conditional PAL/NTSC assembly in
the rev.B source code
1200XL rev.10 PAL/NTSC All info found in an Atari 1200XL. The XL/XE
rev.2 source code refers to it as rev.10.
'Best Electronics' calls it rev.A.
1200XL rev.11 PAL/NTSC Refered to rev.11 by the XL/XE source code.

The following OS roms originate from rare Atari 8-bit systems.
Since I don't own any of these (unfortunately), I don't have much
information about these roms. Who can help me?
I've got two 16K rom dumps from the 1450XLD. Both ID's are rev.3.
The first dated 3/23/1984 comes from the 'Pooldisk Too' CD-ROM
(filename: 1540os3.v0) and the second dated 6/21/1984 was send to
me by Nir Dary (filename: os1450.128). Main differences between
these two are in the first 3K ($C000 - $CBFF).
The XL/XE OS rev.3B is from an Atari from Arabia. It's probably based
on rev.3. There are changes in the fonts (Arab characters) and several
patches in the code. More info at:

More info on what is maybe either the 1985 or 1987 XL/XE OS versions listed
above. From ST*ZMAGAZINE #36, Sept. 1, 1989 (as reprinted in PSAN Nov 89):
by Mark Elliot, Innovative Concepts
The following changes have been incorporated in the 130XE computer.
The O.S. has minor changes like:
A) The MEMORY TEST (from SELF TESTS) tests the extra 64K now! (in 4 squares)
B) Also, the MEMORY TEST checks the first 48K over TWICE as fast as before!
C) The KEYBOARD TEST has the F1-F4 keys missing on top. (function keys),
although the code that interprets them is probably there (like XEGS).
D) Also, it types out "COPYRIGHT 1985 ATARI" at the keyboard test, when all
tests are done. (compared to COPYRIGHT 1983 ATARI, before)
E) And, the O.S. chip itself, is on a 27256 EPROM, but only half of it is
used! (comprared to the original, which was on a 16K x 8 ROM, 27128 comp.

Subject: 7.2) What is the ATASCII character set?
ASCII is an acronym for the American Standard Code for Information
Interchange. Pronounced ask-ee, ASCII is a code for representing English
characters as numbers, with each letter assigned a number from 0 to 127. For
example, the ASCII code for uppercase M is 77. Most computers use ASCII codes
to represent text, which makes it possible to transfer data from one computer
to another.
The 8-bit Atari computers use a modified version of the ASCII character set
called Atari ASCII, or ATASCII.
David Moeser produced this nice translation table.
Piotr Fusik corrected the description of Atari character 5.

Subject: 7.3) What is Atari BASIC?
BASIC is an acronym for Beginner's All-purpose Symbolic Instruction Code.
Developed by John Kemeney and Thomas Kurtz in the mid 1960s at Dartmouth
College, BASIC is one of the earliest and simplest high-level programming
languages, incorporating components of FORTRAN and ALGOL.
In 1978 Atari contracted with Shepardson Microsystems, Inc. (SMI) to create a
version of BASIC (along with a File Management System (FMS)) for the upcoming
Atari personal computers. The following worked together on the project, which
resulted in Atari BASIC (along with the original Atari DOS):
Paul Laughton (author of Apple DOS) - project leader, co-primary contributor
Kathleen O'Brien - co-primary contributor
Bill Wilkinson - floating point scheme design
Paul Krasno - implemented the math library routines following guidelines
supplied by Fred Ruckdeschel (author of the acclaimed text,
BASIC Scientific Subroutines)
Bob Shepardson - Modified IMP-16 Assembler to accept special syntax tables
Paul invented
Mike Peters - keypuncher/computer operator/junior programmer/troubleshooter
In late 1980/early 1981 the development rights to Atari BASIC were purchased
from Shepardson Microsystems by a new company, Optimized Systems Software
(OSS), headed by Bill Wilkinson.
Three Revisions of Atari BASIC were produced: A, B, and C:
A - cartridge produced for use with the 400/800/1200XL
B - built-in to the 600XL/800XL, also produced on cartridge
C - built-in to the 800XL(late models)/65XE/130XE/800XE/XE Game System,
also produced on cartridge.
When running Atari BASIC, memory location 43234 ($A8E2, BASIC ROM) indicates
which Revision of BASIC is running. At the READY prompt, enter
"? PEEK(43234)".
If the result is: You have Revision: Atari Part#:
162 A CO12402+CO14502
96 B CO60302A
234 C CO24947A
On versions A, B, and C, Greg Miller writes:
"Rev A had a number of bugs, not just the commonly described crash bug.
Rev B fixed most (maybe all, I don't remember) of these, but in the
process, they added a new bug. You see, the crashes were caused by a bug
in one of OSS's memory move routines. When the bug was fixed, the fix
mistakenly applied to a routine that actually worked in Rev A, causing the
new lockup problem.
Rev C differs in only a few bytes. AFAIK, the only change was to remove
the alteration made to the routine that was broken by Rev B.
Also concerning versions A, B and C, Russ Gilbert writes (3 Jul 2002):
"I've got an opinion on this, my opinion is wrong to 95% of Atari users.
B is a re-compile of A. C is a 12 byte patch to B.
I've used Atari BASIC for a millenium (?). B has less hangs and
ridiculous stuff like losing DIMs and stuff. C hangs like a lot. I must
admit I don't have very much experience with C as I go back to B after
using C for a short time.
I prefer B. I know its foibles. Just LIST, NEW, ENTER, SAVE every 5 or
6 SAVEs. Also, 0 REM will help with ENTERs that aren't working (put a
immediate 0 REM line before you ENTER.)"

Subject: 7.4) What are Atari DOS I, DOS II, DOS 3, DOS 2.5, and DOS XE?
Here are short descriptions of the various Disk Operating Systems (DOS)
versions produced by Atari for use with their 8-bit computers.
In 1978 Atari contracted with Shepardson Microsystems, Inc. (SMI) to create a
File Management System (FMS) (along with a version of BASIC) for the upcoming
Atari personal computers. The following worked together on the project, which
resulted in the original Atari DOS (along with Atari BASIC):

The original Atari DOS shipped with 810 disk drives until 1981. It consists
of a single file, DOS.SYS, which is loaded into memory from disk on startup.
At the top of the menu screen it reads:
DISK OPERATING SYSTEM 9/24/79
COPYRIGHT 1979 ATARI
With the planned release of DOS II in 1981, Atari referred to this first
release of DOS as DOS I. Nearly all users quickly abandoned DOS I in favor of
DOS II.
Trivia: The DOS I "N. DEFINE DEVICE" menu option does not work.
Also, DOS I is not compatible with the 850 Interface Module.
The Atari DOS I disk is labeled: Atari 810 Master Diskette (CX8101).
DOS II Version 2.0S was shipped with 810 disk drives, and early 1050 disk
drives, from 1981-1983. It consists of two files:
- DOS.SYS is loaded into memory from disk on startup
- DUP.SYS, which contains the DOS menu, is loaded only when needed.
MEM.SAV can be employed to preserve the contents of memory to disk when
DUP.SYS is loaded, so that the data can be restored to memory when exiting
from the DOS menu. DOS 2.0S supports Atari's proprietary single-sided, single
density 90K 5.25" floppy disk format only. DOS 2.0S represents the lowest
common denominator of Atari DOS versions--you can be assured than any Atari
disk drive for the 8-bit Atari can work with disks formatted with DOS 2.0S.
DOS 2.0S can read disks written with DOS I; the reverse is not the case. The
DOS 2.0S disk is labeled: Atari 810 Master Diskette II (CX8104).
DOS 2.0S was delivered by Optimized Systems Software (OSS), headed by Bill
Wilkinson, for Atari.
DOS 2.0S consists of four separate elements:
1. DUP - Disk Utility Package
2. CIO - Central Input/Output
3. FMS - File Management System
4. SIO - Serial Input/Output
DOS II Version 2.0D was shipped with the rare Atari 815 Dual Disk Drive.
Supports double-density disk drives; also supports single-density disk drives.
The DOS 2.0D disk is labeled: Atari 815 Master Diskette (CX8201).
For much more about DOS II see Inside Atari DOS by Bill Wilkinson (1982),
online at http://www.atariarchives.org/iad/ .
DOS 3 shipped with 1050 disk drives from 1983-1985. It was created in part to
take advantage of the 1050's Dual-Density capability, by employing a single-
sided, enhanced-density 130K 5.25" floppy disk drive format. Atari called
this format "dual-density," but the Atari community quickly came to refer to
this format as "enhanced-density" to better differentiate it from widely
available 3rd-party truly double density disk drives and supporting versions
of DOS. DOS 3 uses a disk format incompatible with DOS 2.0S. It included a
utility to convert files from DOS 2.0S to DOS 3, but not back again. It used
disk space less efficiently than DOS 2.0S. For these reasons and others, DOS
3 was not widely accepted by the Atari community, and like DOS I is not
generally used except for curiosity's sake. The DOS 3 disk is labeled: Master
Diskette 3 (DX5052).
DOS II Version 2.5 shipped with 1050 disk drives and early XF551 disk drives
from 1985-1988. DOS 2.5 represented Atari's relenting to the masses,
returning to DOS 2.0S compatability. DOS 2.5 very closely resembles DOS 2.0S,
with just a few features added. It supports both DOS 2.0S single-density 90K
formats, as well as an enhanced density 130K format for use with the 1050 disk
drive. DOS 2.5 also includes a RAMdisk utility for use with the 128K 130XE
computer, a utility to convert files from DOS 3 disks back to DOS 2.5, and
other disk utilities. DOS 2.5 is just about as universal among Atari users as
DOS 2.0S. The DOS 2.5 disk is labeled simply: DOS 2.5 (DX5075).
DOS XE shipped with XF551 disk drives after 1988. Like DOS 3, DOS XE
introduced a whole new format for Atari floppy disks; but unlike DOS 3, DOS XE
also preserved general compatability with DOS 2.0S/2.5. DOS XE supports the
full capabilities of the double-sided, double density 360K per 5.25" floppy
disk XF551 disk drive, including that drive's high-speed burst mode. DOS XE
also fully supports the 90K SS/SD capability of the 810 disk drive, the 130K
SS/ED capability of the 1050 disk drive, the 180K SS/DD capability of most
3rd-party disk drives for the Atari, and a RAMdisk for use with the 130XE.
Date-stamping of files is supported. DOS XE requires an XL or XE computer; it
is not compatable with the 400/800 computer models. Even though DOS XE was
critically well-received, and represented a substantial jump in capabilities
over DOS 2.5, its arrival came so late in the crouded realm of Atari and 3rd-
party DOS versions that it never achieved much acceptance among real users,
and is now relegated to the same status as DOS I and DOS 3 before it. Before
its release, DOS XE was widely known as "ADOS." It was developed by Bill
Wilkinson for Atari. The DOS XE disk is labeled: DOS XE Master Diskette
(DX5090).
Subject: 7.5) What are MyDOS, SpartaDOS, and other popular DOS versions?
Section includes contributions by Andreas Koch (most DOS 2 clone
descriptions); Jeff Williams (12/6/04, Mike Gustafson wrote SpartaDOS)
Atari DOS versions are very popular, but many 3rd-party DOS versions have also
been developed over the years. Of these, MyDOS and SpartaDOS seem to be the
most-used today.
MyDOS 4.53
==========
MyDOS is modelled after Atari DOS 2.0S/2.5, but provides subdirectory and
hard-drive support, along with many other "high-end" features.
MyDOS 4.53/3 was released as freeware by David R. Eichel on 1/1/90.
Defaults to a 3 character file length/free sector count instead of MyDOS's
normal 4. Supports multiple AUTORUNs at boot up (*.AR0 through *.AR9).
Supports Axlon RAMdisks.
MyDOS 4.53/4 is the same as 4.53/3, but uses a minimum of four characters in
the sector count just like most versions of MyDOS.
MYDOS 4.51 was developed by Wordmark Systems (Charles Marslett). Source code
is available as "abandonware" at: http://www.wordmark.org/
MYDOS 4.50 was released on 11/28/88, developed by C. Marslett & R. Puff
http://www.nleaudio.com/css/files/MYDOS45M.ARC
Mathy van Nisselroy's MyDOS page, including recent patches by Lee Barnes:
http://www.mathyvannisselroy.nl/mydos.htm
SpartaDOS 3.2, 3.3, 4.41
========================
SpartaDOS is a completely different command-line DOS modelled after MS-DOS,
though it is perfectly capable of reading all Atari DOS and MyDOS disks.
There are many versions available. Hopefully this list will help keep them
all straight.
SpartaDOS X 4.41 (8 Feb. 2008)
----------------
Greatly enhanced/expanded compared to disk-based SpartaDOS; completely
different source code.
SDX upgrade project
The purpose of this project is to add new functions to the best disk
operating system for the Atari 8-bit computer ever created, and to clean
up few bugs at the occasion. The last SpartaDOS X version (4.22) was
released 10 years ago. Most users got used to its bugs and shortages. New
software and hardware developments, however, made us think about a new,
cleaned up and modernized version of the DOS, which would be compatible
with the 4.22 (from FTe), and enhanced both in software and hardware.

SpartaDOS Pro 3.3a, 3.3b, and 3.3c - 1994-1997
----------------------------------
The SpartaDOS Pro 3.3 versions were developed for FTe by programmers Stephen
J. Carden and Ken Ames, based upon a disassembled copy of the older (more
stable?) 3.2c release from ICD.
-- SpartaDOS Pro Ver 3.3a 3-Nov-94 -- Added MUX support and MS-DOS Commands.
Highspeed SIO routines NOT included. Recommended for use in emulators
(especially Xformer) only.
-- SpartaDOS Pro Ver 3.3b 25-Dec-95 -- Has two different SIOV handlers, one
for the MUX and one for the MIO.
-- SpartaDOS Pro Ver 3.3c 1995 -- Looks at your system and by checking it
determines what CIO handler to load, and has MS-DOS command set. Black
Box, MUX, and MIO are fully supported, though none of these are required.
-- SpartaDOS Pro Ver 3.3c 19-Dec-97 -- The same 3.3c produced on a 16K ROM
cartridge and available for purchase from Video 61.
-- SpartaDOS Pro Ver 3.3d -- Contains additional fixes for MIO users.
unreleased?
According to Lance Ringquist of Video 61:
K-Products contracted with FTe to develop SpartaDOS Pro 3.3 for exclusive use
and distribution with K-Products' BBS Express! Pro, to provide this BBS system
with the most stable platform possible. As Video 61 purchased the rights to
the entire K-Products product line, SpartaDOS Pro 3.3 became a product of
Video 61.
SpartaDOS 3.2g and 3.2gx - Dated 6/4/94.
------------------------
Last official disk-based versions, released as shareware by Fine Tooned
Engineering (FTe), who had purchased the rights from ICD. 3.2g is the primary
version; 3.2gx differs only in that it locates the disk buffers under the OS
to save RAM. 3.2gx is intended for use in systems that include a PBI device
(MIO, Black Box); it is not compatible with BASIC XE nor any other programs
using RAM under the OS.
First shareware release from FTe: 3.2f.
Earlier major releases from the original developer, ICD: 3.2d, 3.2c, 2.3, 1.1
SpartaDOS 1.1-3.2d were written by Mike Gustafson at ICD.
Only the SDX cartridges and the original version 1.1 are compatible with the
400/800 computer models; SpartaDOS 2.x and 3.x require an XL/XE.
Many disk-based SpartaDOS versions are available for download from
Thunderdome, kept by SysOp Fox-1: http://thunderdome.atari.org/ or
http://www.mixinc.net/atari/download_a8/sdsys.htm
BW-DOS 1.30 - FreeWare, published 95-12-17 by ABBUC
===========
Another popular, powerful DOS is BW-DOS (it is pronounced "Bay Vay Dos"),
freeware by Jiri Bernasek - BEWESOFT. SpartaDOS compatible. Does not use any
speeder internally, but comes with external XF551 speeder. Supports 4 drives
and Ramdisk, comes with Ramdisk driver for XE compatible Ramdisks up to
1Megabyte; supports 4 densities: a) Single (90k), b) Enhanced/Medium (130k),
c) Double (180k) and d) DSDD (360k); does not use any RAM under OS ROM (so it
works on an Atari 800 and with Turbo BASIC); unlike SpartaDOS most commands
are external, thus the DOS is only 5kbytes short; supports a PAL clock (made
by ABBUC regional group "ARGS"); comes with many great utilities (which can
also be used with SpartaDOS).
BW-DOS 1.30 disk images and User Manual are available at:
http://atariwiki.strotmann.de/xwiki/bin/view/APG/BeweDOS
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
The other DOS varieties mentioned below are all, like MyDOS, Atari DOS-2
clones and thus DOS-2 compatible; avaiable as PD or Freeware...
TOP-DOS 1.5+
============
Carolyn Hoglin writes:
This superior DOS was written by R. K. Bennett of Eclipse Software in
Sunnyvale, CA. It was based on Atari DOS, but with many, many more features.
It fully supports my double-density, double-sided Astra drives, automatically
sensing the proper density and sidedness of both drives 1 and 2. (MYDOS only
seemed to do that on drive 1.) Also supported are large ramdisks for Axlon,
Mosaic, etc. The latest version was TOP-DOS 1.5+, which came with an
excellent manual explaining how to use its powerful capabilities.
SuperDOS 5.1
============
supports 4 formats SD/ED/DD/DSDD; supports 256k Xtra RAM/RD; supports 4
speeders: Happy+Speedy+XF551+US Doubler and its compatibles; has an AUX.SYS
file with option to use / not use RAM under OS ROM; has unfortunately a very
slow Ramdisk;
BiboDOS 5.4 and 6.4
===================
3 versions avaiable, one without speeder - 5.4NT, one with Happy/Speedy
support 5.4HS and one with XF support 6.4XF; supports 4 formats / up to 360k;
supports 256k Xtra Ram / RD; the DUP.SYS uses RAM under OS ROM, thus Turbo-
BASIC must load without DUP;
Turbo-DOS 2.1
=============
Master-Disk produces 4 different versions: 2.1NT without speeders, 2.1HS for
Happy/Speedy, 2.1XF for XF551 and 2.1EX for 3 speeders: Happy+Speedy+XF551;
supports 256k Xtra RAM / RD and supports use of batchfiles; has converter for
DOS 3 and DOS 4; supports 4 formats, up to 360k; does not use RAM under OS
ROM; DUP uses a Command Processor; all commands are avaiable via HELP key;
works with XL/XE computers only, does not load/boot on Atari 400/800 no clue
why;
RealDOS Ver 1.0a Build 0024 2-Oct-06
====================================
Integrated Logic Systems (ILS - Stephen J. Carden)
A potential modern replacement for SpartaDOS.

Subject: 7.6) How do I modify Atari DOS to support more than two drives?
When running Atari DOS II and compatibles, memory location 1802 ($70A,
DRVBYT) indicates the number of disk drives allocated. At the Atari BASIC
READY prompt, enter "? PEEK(1802)" to read the value of this location.
Possible values include:
1 = Drive 1 only
3 = Drives 1 and 2 (default value)
7 = Drives 1, 2, and 3
15 = Drives 1, 2, 3, and 4
The value of DRVBYT can be changed with the Atari BASIC POKE command. For
example, "POKE 1802,7" to set DOS to support drives 1-3.
To save a changed value for DRVBYT that will be in effect when the computer
starts up, go to the DOS menu (enter "DOS" at the READY prompt), then choose
menu option H, Write DOS Files. This disk will now boot with support for the
number of disk drives of your choosing.
Subject: 7.7) Are there Graphical User Interfaces (GUIs) for the Atari?
Contributors: Andreas Koch, Mathy van Nisselroy, Kathleen Ferrante
- Diamond GOS version 1 (a cart and a PD demo-disk-version do exist),
version 2 (cart only), version 3 (cart only); plus some applications
(painter program, text program, etc.); Diamond GOS has been made
freeware by the author Alan Reeve;
- G.O.S., the Graphic operating system by Total Control systems; two different
versions are avaiable (I call them GOS 1 and GOS 2) and they are PD;
- G.O.E., the Graphic Operating Environment also by Total Control Systems
(this one merely works under Sparta DOS, not with Bewe-DOS and not at all with
DOS 2.x); so far I have found 3 different versions (GOE 1,2,3) with some
applications (graphic/painting program, etc.); PD;
- S.A.M., the Screen Aided Management (unfortunately it has the same name as
SAM, the software aided mouth) from PPP/Germany. It is avaiable in two
different versions: a) the type-in listing from Atari magazin and/or the Lazy
finger disks (which are PD!) or b) the commercial version 2.0 which has many
add-ons and can still be bought from Dean Garaghty/UK or
PD-World-Versand/Germany; This GUI merely works correct under DOS 2.5 and
Medium/dual density, however...
- BOSS-XL, the XL-Desktop from Mirko Sobe; written in Turbo-BASIC; freeware;
http://www.atarixle.de/
- BOSS-XE, the XE-Desktop from Mirko Sobe; written in Turbo-BASIC;freeware,
http://www.atarixle.de/
- BOSS-X the newest desktop version from Mirko Sobe, needs an 128k+ Computer
(128k or more memory), supports MyDOS up to 16MB and MyDOS subdirs...; still
written in Turbo-BASIC; many applications and drivers; freeware;
http://www.atarixle.de/
- XL-TOS a small and "cheap" GUI version from Atari magazin (i.e. a type-in
listing; the BASIC file, which consists of many data lines creates a short
object code file); unfortunately this GUI only looks good, it loads almost
nothing... PD;
- ST-TOS a small BASIC program, that looks like a GUI; it can merely load
BASIC files and do a few DOS commands, like lock, unlock, delete and such...
(PD)
- BASIC desktop, a GUI written in BASIC just as a sample, what can be done
with an 8-bit computer; this one loads BASIC and text files (maybe also ML
files); PD;
- DCS, the desktop construction set from Tom Hunt; there are 3 different
versions avaiable, a) for DOS 2.5, b) for MyDOS andc) for Sparta-DOS; I have
tested the Sparta DOS version, which worked with batchfiles and could easily
load some ML files, text files and BASIC files (which were already on the DCS
disk); it also works with high densities and/or hard disk partitions up to
16MB and supports subdirs of course; hmm, freeware or shareware ?!?
- ATOS - GUI by Tom Hunt/Closer To Home. http://cth.dtdns.net/atos/
1) Lets you use any demo or intro as a screen saver!!
2) Works with all Atari hardware, BB, MIO and Hard drives, SpartaDOS support
3) Lets you run files like full games and demos and then
return back to the desktop. It uses Overlays.
- Atari Desktop by ABC software (Poland), includes editors, converters,
file copiers, sector copy, tape+turbo tape copy, small games, CMC finder
and player and much much more; works with 64k RAM and keyboard input;
disk manuals only in polish language...

or Turbo BASIC and are very restricted; most of them merely look like a GUI
but need to much memory for everyday use. Thats why most users still prefer
those DOS or Gamedos (Gameloader, Multiloader, etc.) programs...
Subject: 7.8) What should I know about modem device handlers?
In order to use a modem on the Atari, a modem software handler, or R: device
handler, must be loaded into memory.
There are several families of R: handlers, corresponding to the different ways
in which a modem may be attached to the Atari.
Except for family #7 below, these handlers are used in one of two ways.
Either they are (A) loaded into memory from DOS just before running the main
terminal application, or (B) the terminal program is appended to the handler,
so that in practice, a single file is loaded from DOS which contains both the
R: device handler and the application itself.
1) 835/1030/XM301 modems. Atari-only modems, interface via SIO
2) MPP/Supra modems. Atari-only modems, interface via joystick port
3) R-Verter cable. Connect standard Hayes-type modems via SIO
/ SX212 modem. A Hayes-compatible modem, interface via SIO
4) SWP ATR8000 interface. Standard Hayes-type RS-232 modems via this interface.
Richard Anderson writes (Oct 2 02):
Mine originally came with a driver program; and, I believe, a BASIC program
to set up the driver from BASIC. Later they shipped with a special version
of MyDOS with the R: handler built in.
5) 850 Interface/P:R: Connection, internal
This type of "mini handler" simply loads the R: device handler code from a ROM
chip inside the RS-232 serial interface. A long beep is heard through the
speaker when the handler is loaded into the computer's RAM.
Many varieties of DOS for the Atari include an explicit provision for loading
this type of R: handler into memory from the 850 or compatible interface.
Also, this type of R: handler is automatically loaded when any 8-bit Atari
computer is turned on with a P:R: Connection or powered 850 connected, but no
powered disk drive is present.
6) 850 Interface/P:R: Connection, external
Used with the 850/P:R: Connection in place of these interfaces' built-in
handlers.
7) MIO/Black Box interfaces, internal
These interfaces utilitize the PBI or ECI parallel ports on the Atari. They
include their own R: handlers in ROM, using no computer RAM at all.
8) MIO/Black Box interfaces, external: Len Spencer's Hyperspeed
This handler is "optional" for the Black Box, but "essential" for the MIO
in order to take full advantage of the high-speed hardware handshaking
capabilities of these two interfaces.

MC's additions: 2006.01.16 Xasm 3.0.0, 2005 from Piotr Fusik
Revision : 2.0
Date.... : 2005-2-20
==============================================================
The goal is to give information about all available languages
for the Atari 8-bit computer. This information includes:
title, last version, author, date and a short description.
It would also be nice to know how to get it and where to get
more information (like reference cards, reviews and such).
Maintainer: Freddy Offenga

==============================================================
There are quite a lot! To get some structure in this section it's
divided into the following categories;
a) ASSEMBLER
b) BASIC
c) C
d) PASCAL
e) LISP
f) FORTH
g) PILOT
h) LOGO
i) All the rest
The following format is used:
- Language titel (medium)
version, year : version, year
author/company : author/company
available..... : where/how to get it
package....... : programs, documentation
features...... : main features
Description.
The question marks (?) indicate that more information is
required about that topic.

XL/XE software won't work on 400/800 if:
1) it uses shadow RAM at $C000-$CFFF and $D800-$FFFF
2) it uses RAM expansions at $4000-$7FFF controlled by PORTB $D301
3) it uses specific XL OS functions (like JNEWDEVC)
4) it uses illegal XL OS addresses.
5) it uses European Charset :)
Andreas Koch adds:
To get an overview or see a chart of OS changes from the 800 to the XL
line, refer to Antic magazine Volume 3, Number 2 (June 1984), pages 10-14;
(online: http://www.atarimagazines.com/v3n2/insideatari.html )
Also note, that some software will not work correct (or not at all) on
newer XE/XEGS versions (which have a new OS with a new version number,
a new selftest/memory-test/keyboard-test, larger RAM chips, etc. etc.);
Thomas Richter contributes further details (16 Jan 2004):
There are a couple of reasons why some games don't run on the XL/XE
models. I try to order them by "likeliness", of course biased by my
personal observations:
i) The printer buffer of the XL Operating System in page 3 is a couple
of bytes shorter. The additional bytes are used for extended OS
variables not available in the 800 series. Most prominent is the $3fa
location, holding a shadow register of GTIA's TRIG3 signal. While a
true joystick trigger line in the 400/800 series, this signal is used
as "cart inserted" signal for XL/XE models. Unfortunately, the OS
compares GTIA trig3 with the shadow register at $3fa in each vertical
blank, running into an endless loop if the register contents don't
match. This causes hangs for games using page 3 either as copy-buffer
or for player-missile graphics. (Hangs by Ms. Pac-Man and
Bacterion! are caused by this, and many others...) This is "fixable"
either by the translator disk, or by a quick hack into the game,
replacing the OS vertical blank or poking TRIG3 frequently into its
shadow. The reason for the OS behaviour might be that Atari wanted to
prevent crashes if the cartridge is inserted or removed while the
machine is running. The 400/800 is powered down when a cart is
inserted, the XL/XE lacks the cover of the older models that triggered
a little switch to interrupt the power line.
ii) Similar to the above, writes to $3f8. This OS equate defines
whether on a warm start, the BASIC ROM shall be mapped back in. If
its contents are altered, a program triggering a reset as part of its
initialization will find itself then with 8K less RAM occupied by
a BASIC ROM, making it crash. Similarly, writes to the cartridge checksum
$3eb could cause a cold-start on a "reset initialization". This is
fixable by the translator disk.
iii) Some games use a four-joystick setup, or at least initialize
PIA itself. If this happens inadequately, PIA Port B, bit 0 gets changed,
disabling the ROM, and thus crashing the machine. This is not fixable
by the translator since it is a hardware issue.
iv) Direct jumps into the OS ROM, not using the documented vectors in
the $e450 area. Interestingly, this fault is not as common as it may
sound since games hardly ever use the OS. It causes failures of
some "serious applications", most notably "QS Forth" and applications
compiled by it. This is fixable by the translator disk.
As a side remark, it is interesting to note that no such documented
jump-ins exist for the math-pack ($d800 to $dfff). It is not really
part of the OS, but looks more like a part of the BASIC interpreter
that didn't make it into the OS because there was no room left. Thus,
direct jump-ins have to be used here that are documented in the De Re
Atari (for example). Atari never changed them, but it seems likely
that this documentation happened more or less as an accident since the
same source also lists some mathematics-related jump-ins into the
Basic (namely, to compute SIN and COS and related) that are only valid
for the Rev. A BASIC. Thus, the math pack might be a couple of
routines that have been originally intended for "private use" of the
BASIC ROM, but then have been found "too useful" by many others to
remain "closed". Otherwise, it is hard to explain why the otherwise
pretty cleaned-up OS comes with a construction like this.

RE: Missile Command, Andreas writes:
there are many different versions available... I know the old Atari 800
cart version, which works correct with Joystick and Trakball, but not at
all with a mouse. The newer XL version works with Mouse, trackball and
Joystick, also the newest (built-in) XEGS version of MC. But, there is
also a tape version (and maybe a disk version) of MC available. I am not
sure if this tape version behaves like the old 800 version or like the
newer XL and XE/XEGS versions...

Maybe you did not know, there is a little difference between Trackball
and ST-mouse. Although MC works with both input devices does not mean,
they are the same. they are not !! Connect the TB to an ST computer and
you see: it does not work at all !! You have to do a small conversion to
convert the TB to an ST mouse. (Plans are avaiable from ABBUC, Germany).

Well, I will not go into details with the disadvantages and possible

might be the unavailability of the Selftest, XL/XE Basic, RAM under the

Allthough these RAM upgrades are relatively easy to build
(and to install into the computer), they make problems with
quite some software. Some programs tend to use the base RAM
as extra RAM / Ramdisk with these upgrades, which will most
often result in a crash of the computer. Next, most extra RAM
testers will show more extra RAM (or a bigger Ramdisk) than
there is really available (e.g. with a 256k upgrade you will
see 240k extra RAM, but there is only 64k base RAM + 192k
extra RAM). Alas, this is a typical hardware problem for these
upgrades and it cannot be solved or avoided with software...

I am quite sure that it is possible to write some drivers and thus
use the Atarimax Flash-ROM carts as extremely fast floppy drives!)
- Flash-ROM cart 1024k / 8Mbit "Atarimax" by Stephen Tucker
(for information and complete documentation plus software see:
www.atarimax.com/flashcart/documentation/index.html )
- and many others I do not know and I do not have any info about;
Even cartridges can be used as Ramdisks (= fast floppy drives),
especially RAM-carts or Flash-RAM carts. But they function like
most other Super- or Mega-Carts, meaning the bank-switching
techniques are also used there. Since the subject carts and
bank-switching carts is quite enormous, I will not discuss it or
present any information here. Just try to find a large description
by John K. Picken ("RAM/ROM Control on an XL/XE") if interested in that
subject (e.g. at Jindrich Kubec`s homepage: www2.asw.cz/kubecj/... ).
Finally thanks and credits for this subject and lots of (used /
borrowed) information therefore go to: Lee Barnes, Russ Gilbert,
Mathy van Nisselroy, Erhard Puetz, Mathias Reichl, Ron Hamilton,
Wes Newell, Guy Ferrante, XI of Satantronic, Bernhard Pahl, Walter
Lojek and Voy/Dial. Also thanks to John K. Picken who wrote an
excellent article about A8 extra RAM / Ramdisks and A8 cartridges and
their technique of bank-switching. I know this list has still some
errors and is missing some information, alas, without your help I am
unable to correct the errors or to fill in the missing information...

Please note, that hackers, crackers and pirates also made file versions
of (most of) the XE / XEGS 64k and 128k carts available. Due to cart.
bankswitching, a 64k XL/XE was enough for these super-carts; not so with
the file versions, they do (mostly) require more than 64k memory...
Next, there are also "un-official" (pirated, hacked, cracked, patched)
cart. versions of former disk-based games, that require XRAM, which they
originally did not (example: Conan, the multi-stage disk-version by
Datasoft requires 64k RAM, whereas the single-stage version of the
Sunmark multicart. req. 128k RAM). It is quite likely, that more games
will occur in the Atari scene with the same behaviour...

Subject: 8.13) What voice/sound synthesis software is there for the Atari?
This section by Andreas Koch.
- S.A.M. - the Software Automated Mouth by Don't Ask Software (a
software package; you can find it at Don`s / the author's homepage:
http://www.retrobits.net)
- Softsynth (a PD program, that creates sounds and sound effects via
modulation of the tv/monitor speaker; available from the ABBUC library);
- MOD-Sounds (sound-MODulation, allthough I do not know any software to
create such sounds on an A8, some programs to edit (Protracker) and
playback (Inertia, Modplayer, Neotracker, etc.) these sounds do exist);
Subject: 8.14) What programs support stereo and upgraded sound?
This section by Andreas Koch.
(POPS info updated 8/15/06 by mdc thanks to Lee Brilliant)
There is already a lot of stereo software for the upgraded Atari computers
available, of course most of these programs are limited to certain/special
upgrades and merely perform their stereo effects on these items (with
otherwise upgraded or non-upgraded Ataris, the sounds or programs will
only play in mono):
a) software for the various stereo-upgrades:
- 3 channels with one Pokey (POPS-software): Afaik for this kind of upgrade,
there merely exists a patched version of the Pokey player program, I am
not sure if there is anything else for it; anyway, refer to Analog
Computing, issue 66, november 1988, pages 54 -60;
- stereo with two computers (thus two Pokeys): Afaik for this simple trick
there merely exist two programs, they are "Perestroyka" and "Sky
Network" by T.Liebich. In order to achieve the stereo effect, you
have to boot/load one of these demos on two computers (connected to
different TV's or monitors, there is no need to connect the computers to
each other!). When done, press 1-5 on the first computer while pressing
Shift-1-5 on the second computer. Meaning, if you want to hear the first
sound in stereo then press 1 on computer 1 and press Shift-1 on
computer 2 simultanously (that`s a little tricky, I know). If you want
to hear sound 5 in stereo, then press 5 on computer 1 and Shift-5 on
computer 2 simultanously. Tricky at first, but sooner or later you will
get the hang of it. Of course you can also connect the two Ataris to
a hifi-system, using the sound output of one Atari for the left channel
and the sound output of the other Atari for the right channel...
- stereo-sound with Stereo-Blaster Pro (Portronic/AMC): Afaik there was
at least one demo disk (early version was single-sided only, later
versions were double-sided), that contained some demo-software, namely
the simple "Stereo-demos" (by AMC, side 1) and the "Stereoblaster-Demo"
(by HU-Soft, side 2 if available). The Stereoblaster demo was written
in Turbo-Basic and played back via Compiled-Turbo-Basic, it uses Chaos
Music-Composer Sounds (*.CMC) and a few of these provide stereo effects,
if equipped with a stereo-blaster-pro and a hifi-system. The simple
stereo-demos included some programs written in Atari Basic, for example
a (pong-like) bouncing ball and a flying helicopter. Equipped with a
stereo-blaster-pro and a hifi-system, one could see the ball bouncing
left and right and simultanously hear the sound fx on the left or right
channel. The helicopter started at the left side and produced a loud
sound on the left channel, when it was flying to the right side, the
sound faded on the left channel and got louder on the right channel,
until the helicopter disappeared (and the sound completely faded away).
There were some more of these simple demos available, but I don`t
remember them anymore.
- Stereo with two Pokeys: There already exist dozens of sounds and demos,
that support this upgrade, most of these programs were made in Poland,
but a few sound-demos were also made in other countries. Anyway, the
following programs support stereo via two Pokey chips:
- Alf-Demo by the Unknown Base (Netherlands);
- Alpha-Demo by GMG (Slovakia);
- AMS-Stereo player by ??? (author unknown), USA;
(there are at least two AMS-stereo-players, that let you play
*.AMS sounds in true stereo or at least simulated stereo!);
- Ballada sound by DJ V / BK (Poland);
- Base 33 by AIDS (msx by Greg, Poland);
- Chaos Music Composer version x.x patched by ??? , Poland;
(=> the original version by Janusz Pelc / LK Avalon is only mono,
but there is a stereo-patch available, as well as various patched
CMC stereo-versions on the internet);
- (many) *.CMC sounds created by one of the many stereo-versions of
Chaos Music Composer;
- Cogito-Demo by AIDS (Poland)
- Do you see the light? sound-demo by Roemer of UNO (Germany);
- Draconus, patched version by ANG and/or Micro Discount (NL/UK)
(the original version by Zeppelin games is only mono!);
- Dynakillers (Game) by GMG, Slovakia;
- First of All (sound) by Raster, Czech Republic;
- Impossible but Real Demo by MacGyver (Poland);
- King of Aggregat by X-Ray / Slight (Poland);
- Megaplayer Versions 1.6 and 2.0 by MacGyver (Poland)
(=> and thus all *.CMC, *.MPT, *.TMC, etc. sounds played with
this sound-player tool can be heard in true or simulated stereo!);
- Multi-Pro-Tracker 2.4s by Jaskier/Taquart, (original mono version
by SoTE; thus *.MPT sounds can be generated in stereo!), Poland;
- (many) *.MPT sounds created by the stereo-version of Multi Protracker;
- Nazebany by DJ V / BK (Poland);
- Overload sound by X-Ray / Slight (Poland);
- Raster Music Tracker 1.x by Raster, Radek Sterba (a PC program
that creates mono or stereo *.RMT sounds that can be played back
on the A8 or any Atari 800/XL/XE emulator);
- *.RMT stereo-sounds created by Raster Music Tracker;
- Stereo-Patch for Pokey Player by Chuck Steinman
(=> thus all Pokey-Player / *.V sounds can be heard in stereo!);
- Stereo-Patch for Softsynth by Freddy Offenga (Netherlands)
(=> thus Softsynth will create stereo-sounds!);
- Stereo Patch for World of Wonders by Freddy Offenga (Netherlands)
(World of Wonders is a great Softsynth sound-demo!);
- Still Alive (TMC-sound) by Greg, Poland;
- Time sound by X-Ray / Slight (Poland);
- Theta-Music-Composer version 1.x by Jaskier/Taquart
(=> thus *.TMC sounds can be generated in stereo!);
- Theta-Music-Composer version 2.x by Jaskier/Taquart
(supports 1, 2 or even 4 Pokey sound-chips !)
- (most) *.TMC sounds created by Theta Music Composer;
- Vanity sound by Kuchara / Excellent (Poland) ;
- Worms (320k-Demo) by Datri, Czech Republic;
- Zybex, patched version by ANG and/or Micro Discount (NL/UK)
(the original version by Zeppelin games is only mono!);
- thats all what I found so far...
b) software for other sound enhancements:
- enhanced-sound with Covox: Afaik this upgrade will playback digitised or
sampled sound in 8Bit resolution rather than in 4Bit resolution. The
following programs support the Covox-Upgrade:
- Inertia 2.x, a MOD-player by MadTeam;
- Inertia 3.x, a MOD-player by MadTeam
- Inertia 4.5, a MOD player by MadTeam;
- Protracker 1.5, a MOD-editor and player by MadTeam;
- NeoTracker 1.x, a MOD+NEO+SMP player by EPI/Allegresse;
- that's all I have found so far;
note that all these programs will still work with pokey...
Subject: 8.15) What games support online action via modem?
This section by Andreas Koch.
- Modem Chess, a PD game in Basic by ???
- Modem-Battleships, a PD game in Basic by ???
- Tele-Chess, a PD game in Basic by ???
- Jelly Beans a ML game by Chris Martin
- "Battleships ST-XL" by Florian Dingler
(german name: Schiffe versenken ST-XL)
- Midi Maze by XANTH (prototype)
- Commbat by Adventure International
(I have also seen an advert from GCP in Analog or Antic, that listed
the following games: The City, Cybertank, Cybership, Bio-War, Lords
of Space; I am not sure if they are all available for the Atari, A.K.)
To play these games online, one would not only require an Atari computer,
but also a modem, a modem-driver and/or a terminal program (like Kermit,
Bobterm, Teleterm, A-Term, Ice-T, BBS Express Pro, etc.). See also the
sections 7.8, 10.1 and 10.2 which tell you more about modem/terminal
programs and modem hardware for the Atari. Emulator users have it a little
easier and can use the built-in modem emulation in Ape-DOS, Ape-Win,
Atari 800 DOS, Atari 800 Win, etc.
Subject: 8.16) What programs support Atari computer networking?
This section by Andreas Koch.
There are two different hardware add-ons which provide a "computer-
network" (two or more Ataris linked together). Thus, there is software
that supports either one or the other hardware (namely Gamelink-1 or
Gamelink-2). The following software supports the networking hardware:
- Gamelink-1 (by Dataque):
- info-text about GL-1 and where to buy it, by Dataque;
- Tic-Tac-Two by J.Potter/Dataque, a tic-tac-toe clone;
- Modem-Battleships, patched by Rick Detlefsen for Gamelink-1;
- Gamelink-2 / Multilink (by Dataque & Bewesoft):
- Maze of Agdagon demo (1 player only) by Dataque;
- Maze of Agdagon (full version, 2-8 players) by Dataque;
- Multi-Dash (2-8 players, XL/XE only) by Bewesoft;
- Multi-Race (2-16 players, XL/XE only) by Bewesoft;
- Multi-Worms (2-8 or 2-16? players, XL/XE only) by Bewesoft;
- "starter-kit" module to use in your own networking-games by Bewesoft
(free use of this module is granted by Bewesoft/Jiri Bernasek);
- Speed-Up by Radek Sterba
- Speed-Up Gold by Radek Sterba
Subject: 9.1) How can I work with .arc files on my 8-bit Atari?
ARC.EXE for MS-DOS was released by System Enhancement Associates (SEA) around
1985. It will compress and store groups of files as one file, making it
easier and quicker to download programs and support files at once. Because of
the ease of use and availability of this program, it quickly became the
defacto standard for file archives on Intel-based IBM machines. Files
compressed and stored with ARC or a compatible utility are normally given the
filename extender ".arc".
The 8-bit Atari computers have several software utility options that are fully
compatible with ARC.EXE, the most important being:
Super UnArc 2.4 and Super Arc 2.4 - shareware by Bob Puff, released 01/31/89
Available:
http://www.nleaudio.com/css/files/superarc.arc (complete package + docs)
Also, SpartaDOS X includes a fully compatible ARC command for both creating
and extracting .arc files.
Subject: 9.2) What file formats for entire disks/tapes/cartridges are there?
It is now common, especially when working on Windows PCs or Macs, to work with
Atari software as files or "images" containing the data from an entire disk,
data cassette, or cartridge as duplicated from the native media for the Atari.
Here is a list of file formats, arranged by their associated filename
extensions. These are all filename extensions used to name files containing
entire 8-bit Atari floppy disk images, cassette tape images, or cartridge
images.
.DCM -Image format invented by Bob Puff for his Disk Communicator 3.2 utility.
Used when working with native Atari hardware.
DISKCOMM is at http://www.nleaudio.com/css/files/DISKCOM.ARC
DCM specs at: http://home.planet.nl/~ernest/diskcomm.zip
.ATR -Image format invented by Nick Kennedy, for his SIO2PC project.
Used with most 8-bit Atari emulators running on other computer
platforms. SIO2PC is at http://www.cox-internet.com/wa5bdu/sio2pc.htm
.XFD -Image format invented by Emulators Inc, for their ST Xformer emulator.
Identical to ATR except without the 16 byte header.
Used with ST Xformer and PC Xformer emulators.
Xformer is at http://www.emulators.com/
.PRO -Image format invented by Steven Tucker, for his APE ProSystem device.
Used with APE, the Atari Peripheral Emulator.
APE and APE ProSystem are at http://www.atarimax.com/
.SCP -SpartaDOS SCOPY image file. SCOPY was a utility by ICD.
.DI -Image format invented by Kolja Koischwitz & Christian Kruger for their
800XL DJ emulator for the Atari ST.
.CAS -Cassette image format invented by Ernest R. Schreurs, for his
Digital Cassette Image system (includes CAS2SIO, WAV2CAS, and CAS2WAV
MS-DOS utilities. See: http://home.planet.nl/~ernest/
.ATX Image format invented by Jorge Cwik, for VAPI project. Goal of Vapi is
the preservation of Atari software in its original unmodified form,
including custom format or copy protection. http://vapi.fxatari.com/

Subject: 9.3) How can I copy my copy-protected Atari software?
Russ Gilbert writes:
Almost all commercial software for the A8 is/was copy protected. For boot
disks, this usually involved a large number of special formatting that
couldn't be copied using ordinary sector copiers. Usually the boot process
involved checking to see if a certain sector error occurred, then proceeding.
If the error did not occur, the disk was a copy and would not work.
For carts, usually the method of protection was to write to the cart area of
memory and see if the value changed. If the value changed, the cart program
was in RAM, not ROM and would fail to operate.
For tapes, again a fair number of schemes were used. Some varied the speed at
which the tape loaded. I'm not familiar with tape protection schemes.
With all software media (cart, tape, disk), there may be program encryption,
which must be decrypted before the program can run. This to make more
difficult disassembly of the program.
There were/are a number of products to defeat copy protection/allow copying of
protected software for the A8. The most common way to defeat copy protection
was to disassemble the software and revise sections of code so that the copy
protection was defeated. A software with defeated copy protection is called a
'cracked' software. The basic procedure is to understand how cart/tape/disk
software initializes, loads and runs. Usually make a file out of the software
and 'follow the code', starting with loading of the program, to decryption to
the actual running of the program. Today, it is unnecessary to copy original
commercial A8 software because it has already been defeated and may be found
at a few FTP sites.
Besides 'cracking' software, there were/are hardware devices to copy
commercial protected software. The Happy 1050 and the Archiver, and probably
other modifications to the 810, or 1050 allowed 'bit image' copying and
reproduction of the special formatting that copy protected disks had. Using
these archiving disk drives, a copy of the original disk, including all
special formatting and the original code is copied, thus making a copy
protected copy, not cracked, just like the original.
For carts, copying could involve cracking or again there were/are products to
reproduce the cart and simulate a ROM. Or the cart might be copied and burned
on the correct type of eprom, to make a plug in cart. 'The Impersonator', the
'Pill' are two cart copy schemes copy the cart to a file, then don't change
the code, but use a 'dummy cart' to fool the software into thinking there is a
ROM present.
Basic tools for copying, then cracking, carts and disks are a sector editor
and disassembler. Carts are usually most easily dumped using a special OS,
like Omnimon, to interrupt the cart and dump memory to disk. There are a few
pd cart copiers that have the user plug the cart in when the program is
running, I don't believe these pd cart copiers are very good or very wise to
use.
So, the basic answer to 'how do I make a copy of my copy protected commercial
software' is don't bother. Find it on the net.
There is one exception, in that this 'solution' involves a minimum of effort
and is relatively safe. I refer to 'Chipmunk' and 'Black Patch' software to
make cracked boot disk copy of commercial disks. HOWEVER, even if you use
these two commercial archival tools, be sure you write protect your originals,
and be careful not to accidentally write to the original disk.
Finally, I'll mention a very modern (I mean 1997) product. The APE ProSystem,
by Steven Tucker, in the registered version of this shareware allows making
disk images called 'Pro' images. APE (Atari Peripheral Emulator) requires a
cable, called the SIO2PC cable, that connects the A8 13 pin serial port to a
serial port on the IBM PC clone. To make 'Pro' images, a special adapter
cable is needed, not just the 'standard' SIO2PC cable. The 'Pro' image can
'capture' the copy protection of an original commercial disk. The 'Pro' image
can then be loaded into an A8 using the APE registered version software, thus
backing up your original disk software. Note the 'Pro' image will only be of
use to person(s) owning registered APE software and 'Pro' adapter cable.
Subject: 10.1) What programs can log in to other computers via modem?
Here are some of the more popular PD/freeware/shareware terminal emulator and
related programs available. Use one of these programs for accessing a dial-up
Bulletin Board System (BBS) with your Atari, or for accessing a dial-up "shell
account" with your Internet Service Provider (ISP). Dial-up shell accounts
are no longer widely available here in the 21st century! (There is no
general-purpose PPP capability for the 8-bit Atari that I am aware of.)

Subject: 10.2) What programs can I use to host a BBS on the Atari?
"A BBS, plain and simple, is some hobbyist setting up their own computer to
answer incoming calls from other hobby computers. The visiting person
leaves messages on this computer for other visitors, plays games while
visiting, sends and receives files, and all that." -- Greg Goodwin, 2005
The 8-bit Atari was particularly popular for hosting a dial-up Bulletin Board
System (BBS).
This section attempts to list all BBS programs for the Atari. Of these, BBS
Express! Professional and Carina II BBS seem to be programs that stand up well
even today.
Contributors to this section include: Winston Smith, Steven Sturza, Chad
Hendrickson, Don Fanning, Matt Singer, Pete Davis, Jeff Williams, Rod Roark
o AMIS BBS -- The Atari Message Information Service
original version by Tom Giese of Michigan Atari Computer Enthusiasts. pd.
The "granddaddy" of BBS programs for the 8-bit Atari.
The AMIS BBS was written in BASIC. It included designs for a ring-detector.
You needed a sector editor and had to allocate message space by hand, hex byte
by hex byte.
Several versions of AMIS:
* Standard AMIS, original version by Tom Giese
* MACE AMIS - from the Michigan Atari Computer Enthusiasts,
by Larry Burdeno and Jim Steinbrecher
* Fast AMIS
* MPP AMIS by Matt Pritchard
* Comet AMIS by Matt Pritchard and Tom Johnson, with Trent Condollone
"AMIS so modified that it didnt resemble AMIS"
* AMIS XM301 - Mike Olin and and Mike Mitchell
* TODAMIS 1.0, for 1030/XM301, 1986, Trent Dudley
* Carnival BBS, see below
* FoReM was derived from AMIS, see below
o ARMUDIC, by Frank Huband
From the Atari club of Washington, D.C.
Greg Leslie writes "It was written (in BASIC with machine language
subroutines) by Frank Huband, and the name came from the numbers used to dial
the original BBS.
o ATABBS - Atari Bulletin Board System
Rod Roark writes (3/12/03):
This is really straining my memory -- don't recall exactly
when I wrote the thing (maybe '80 or '81), but as far as I
know ATABBS was the world's first BBS for the Atari 400/800.
I ran it out of my condo in Atlanta on a 48K 400 with an 80K
floppy drive and a 300 bps Hayes Smartmodem. The 48K memory
module was a third party add-on, not Atari's.
It was written in Atari BASIC with a few bytes of machine
language thrown in.
o AtariLink -- by Pab Sungenis.
From his blog at http://atari8programming.blogspot.com/ on 3/20/06:
In 1985-1986 I wrote and eventually released the AtariLink BBS software. This
came out of necessity, since most Atari BBS programs at the time (especially
FoReM and its bastard children) didn't fully support the 1030 modem that I
used (or the XM301 that followed afterward). I eventually adapted the program
to work with Atari's 1200 bps SX212 modem when that was released, and in the
process threw the program open to just about every modem out there. AtariLink
floated in the wild, passed from BBS to BBS for a while, before an Atari
magazine (I forget which one) distributed the software as its disk of the
month.
o ATKeep -- An Atari 8-bit version of CITADEL BBS, by Brent Barrett
ATKeep is a Citadel-like BBS system for eight-bit Ataris. ATKeep runs under
SpartaDOS and requires BASIC XE and 128K of RAM. Originally "MBBBS (Message
Base Bulletin Board System) 1.0, March 24th, 1986" MBBBS was changed to Atari
Keep, or, ATKeep for short, around version the time version 4.0 was released
(June 15, 1986).
ATKeep 7.0 finally took the aide and cosysop commands out of a menu section
and put them into extended commands, where they belonged. It also added a
SYSOP level command set. Users were no longer "users" "aides" or "cosysops,"
they had become level "A" (SYSOP) through level "Z" (READ ONLY). The system
had become extremely complex. Public, hidden OR password protected PRIVATE
rooms. Each room now had its own access level (thus keeping people of lower
level from getting in EVEN if they knew the room name). Each room was
assigned a RWRT (or Read WRiTe status), which determined who could enter
messages in it, and whether or not public or private messages, or both were to
be allowed.
Before version 7.0, ATKeep only worked with the Atari 1030 or XM301 modems.
ATKeep 7.0 was rewritten to accomodate the 850 or PRC interface allowing use
of any Hayes compatible modem.
ATKeep version 7.50 was released (1987), was version 8 released?
o BBCS -- Bulletin Board Construction Set, by Scott Brause/Antic, 1985
A machine language program, developed as the Jersey Atari Computer Group
(JACG) BBS system.
BBCS was known for it's great flexibility. The sysop was offered easy
customization by the use of menus. Many BBSes before it required that you had
to actually change the BASIC code in order to customize your BBS.
Unfortunately, it also suffered from a reputation for stability problems.
o BBS Express! -- 1986, Keith Ledbetter/Orion Micro Systems
Written in compiled Action!. 1030/XM301 and 850 versions.
o BBS Express! Professional ("Pro!")--6.0b 1999, Lance Ringquist/Video 61
Originally released in 1988 by Keith Ledbetter and Chris King from Orion Micro
Systems. Later purchased by Bob Klaas of K-Products, before most recently
being purchased by Lance Ringquist/Video 61.
See also http://cth.dtdns.net/pro/pro1.html
Written in 100% machine language.
Requires XL/XE, SpartaDOS 3.2+, hard drive highly recommended, or at least a
large ramdisk. R-Time 8 is fully supported.
o Carina II BBS -- v2.7 (1995), David Hunt/Shadow Software
Carina II was originally developed by Jerry Horanoff.
Requires an XL or XE computer, at least 500K of storage capacity (including
ramdisk and drives), and SpartaDOS version 2.3 or greater.
Recommended: 192K ramdisk or greater, and an R-Time cartridge.
Fully supported: An MIO interface and a hard drive.
Pete Davis writes (15 Aug 2002):
Carina was a pretty powerful BBS system. Though it was written in BASIC (with
a number of machine language routines), it was expandable and had was able to
load new BASIC programs with the BBS running. In fact, it was quite modular
and would load different sections of the BBS at runtime. I actually used it
when I ran a BBS some time back.

o Carnival BBS -- "essentially AMIS with an overlay to allow for private
messages and passwords." -- Antic
o FoReM BBS -- Friends of Rickey Moose BBS. By Matthew R. Singer.
At the time, there were a lot of BBSs around called things such as "FORUM-80"
and "BULLET-80", ergo the name. FoReM BBS was the first truly RBBS-like BBS
for the ATARI 8-bit. It was programmed in BASIC and was somewhat crashy. I
think that this is the great-grandparent of the FOREM-XE BBSs that survive
today.
Matt Singer writes:
FoReM BBS derived from an early AMIS. When multiple message areas were
added the name was extended to FoReM 26M. Then, When OSS released BASIC
XL the program was rehacked and called FoReM XL... Bill Dorsey wrote most
of the Assembler routines (where is he now?).
o FoReM MPP BBS -- by Matt Singer, sold by MPP
FoReM BBS version for the MPP direct-connect modems.
o FoReM XL BBS -- by Matt Singer.
FoReM BBS updated to take advantage of BASIC XL from OSS.
o FoReM XE BBS -- by Matt Singer
This version of FOREM BBS requires the commercial BASIC XE cartridge in order
to run. It is in the public domain and can import and export messages from
the Atari PRO! BBS EXPRESS-NET (7-bit text only, control ATASCII graphics are
reserved for message data-structure bytes).
o FoReM XE Professional BBS / FoReM XEP BBS -- by Len Spencer
A re-write of FoReM XE BBS, last version was 5.4, Jan 5 1993.
FXEP requires an XL/XE computer with at least 128k of memory, the BASIC XE
cartridge from OSS/ICD, SpartaDOS 3.2 (this program will NOT work with any
other version), and at least 500K of storage.
FXEP is in the public domain, http://www.lspenc13.us/Lenspencer/atari8.htm
o MBBBS (Message Base Bulletin Board System)
-- early name for ATKeep, see above
o NITE-LITE BBS -- Paul Swanson's BBS with RAM disk.
Paul Swanson was a programmer from the Boston, Massachusetts, USA, area.
"1983: Nite-Lite B.B.S. goes on the air. (Was it running A.M.I.S. ?) It is
called "Nite-Lite" because the computer monitor casts an eerie glow about the
room. 1984: Paul Swanson writes his own BBS hosting software for the ATARI
6502 8-bit computer. He names it "Nite-Lite". The Nite-Lite BBS hosting
software goes on to be the most successful commercial BBS software ever
written for the ATARI 6502 8-bit computer. 1989: Nite-Lite BBS puts in a
second line. (MichTron boards eventually take the place of all of the ATARI
Nite-Lite boards.)" - Winston Smith
This BBS was the first to support a RAMdisk, which Paul Swanson called a "V:"
device for "virtual disk". This BBS was written in Atari BASIC and required a
joystick hardware "dongle" device. This was notable as being one of the first
Atari 8-BIT BBSs that could actually go for a week without having to be
rebooted. Pointers to the message base were kept in an Atari "very long
string" (for which Atari BASIC is famous). The BBS would only have problems
(for the most part) if this string became corrupted.
o OASIS (the commercial version) / OASIS Jr. (the pd version)
The original OASIS BBS System was written by Rich Renner and Ralph Walden with
tech support and input from Leo Newman. It was first published by OASIS BBS
Systems (Renner/Walden/Newman) in 1986, and distributed by Leo Newman. Later,
the rights were transferred to Glenda Stocks/Z INNOVATORS, then later (1991)
to Jeff Williams ("Alf").
All machine language. OASIS is very crash-resistant and comes with a "dial
out" screen so that the Sysop can use the BBS as a terminal program to call
and fetch files without having to bring the BBS down and reload a terminal
program. OASIS supports "Door programs" which it refers to as "OASIS PAL
modules". An excellent message system, and a complex file system. It
consists of "file libraries" with suites of "file types". There is quite a
bit of overhead involved in performing a download (which may be a good thing,
as it discourages file hogs). OASIS IV performs networking. SpartaDOS 3.2x
recommended, but any DOS supported. R-Time 8 clock cartridge supported.
Glenda Stocks writes at http://world.std.com/~snet/glenda.htm :
I purchased the source code rights to OASIS and began marketing the BBS
software to Atari 8-bit enthusiasts around the world. I felt that I had the
superior BBS software because I had programmed in the ability to run external
programs, including online games and user surveys. I also had added color
prompts for IBM clone users who called Atari boards running my OASIS software.
Sometime in 1991...I sold the rights to OASIS to a man in Canada..
Jeff Williams ("Alf") writes: (12/6/02)
OASIS was around prior to either PRO or BBS Express IIRC. I don't know when
exactly it showed up, version 3.09 was the first one I remember seeing. What
made it nifty was it was very fast, being all assembler, and having some
different features that things like Forem & Carina didn't have. Compared to
something like Forem MPP at the time, it was kind of amazing.
Ralph Walden sold it to Glenda Stocks, who chopped it up into modules and sold
it as ver 4.7. PRO was out by then, and was a much more complete offering
imo. Glenda wrote some modules for 4.7, but it never really went anywhere
because the architecture was so cramped with her changes.
Eventually she gave up and sold me the source. I looked it over and realized
it was a mess and nothing was going to happen with it. I worked on a version 5
for a while, but never made much progress.
o SMART BBS -- by Marco Benton.
This program is written entirely in BASIC. It expects to be running under a
SpartaDOS environment. This BBS program uses a "modem clock string" rather
than an R-Time 8 cartridge in order to retrieve the current time. It also
comes with an Atari BASIC game door called "Sabotage".
o TART-BOARD, by Bob Alleger
Early Atari BBS.
Subject: 10.3) How can I read/write 8-bit Atari disks on an MS-DOS PC?
There are several programs that allow an MS-DOS system to work with an
Atari-format 5.25" diskette. Each of these work with the Atari SS/DD 180K
format, so you'll need an Atari DOS and disk drive capable of this format.
#1 Choice:
Atari-Link PC (AtariDsk) V1.2 (c) 95-12-09 by HiassofT (Matthias Reichl)
Ataridsk is a program for MSDOS-PCs that allows you to access Atari floppy
disks in double density (180k). All you need is a PC (XT or 286 should be
sufficient) and a 5.25" floppy drive. Features of this tool:
* Menu driven user interface
* read, write and format Atari disks on the PC
* small size (only 35k)
http://www.horus.com/~hias/atari/
Also by HiassofT (Matthias Reichl):
WriteAtr V0.92b
With WriteAtr you can write double density ATR-images to Atari floppy disks
on your MSDOS-PC. You can also create ATR-images of double density floppy
disks! All you need is a PC and a 5.25" and/or a 3.5" floppy drive.
Version 0.92b added experimental support for the enhanced density (1040
sectors/128 bytes per sector) format. Please note: this format doesn't work
with a lot of floppy controllers - use it at your own risk!
http://www.horus.com/~hias/atari/
#2 Choice:
MyUTIL by Mark K Vallevand. Based on Charles Marslett's UTIL.
http://www.umich.edu/~archive/atari/8bit/Diskutils/Transfer/myutil.zip
Includes SpartaDOS disk utility v0.1e to access 180K SpartaDOS disks
Other similar utilities:
ATARIO by Dave Brandman w/ Kevin White - Reads SS/DD 180K Atari disks.
www.umich.edu/~archive/atari/8bit/Unverified/Diskutils-redist/atario21.arc
SpartaRead by Oscar Fowler - Reads SS/DD 180K SpartaDOS disks.
http://www.umich.edu/~archive/atari/8bit/Diskutils/Transfer/sr.arc
UTIL by Charles Marslett - Reads/Writes SS/DD 180K Atari disks.
http://www.wordmark.org/
Here's some advice on using the above utilities from Hans Breitenlohner:
There are two technical obstacles to interchanging disks between
DD Atari drives and PC drives.
1. The Atari drive spins slightly slower (288 rpm instead of 300 rpm).
If you format a disk on the Atari, then write sectors on the PC, it is
possible that the header of the next physical sector will be overwritten,
making that sector unreadable. (The next physical sector is usually
the current logical sector+2). The solution to this is to format all
disks on the PC.
(Aside: Does anybody know how this problem is handled on the
XF551? Is it also slowed down?)
Konrad Kokoszkiewicz answers:
"The XF551 disk drive is not slowed down - these drives are spinning
300 rotations per minute. To prevent troubles with read/write disks
formatted and written on normal Atari drives (288 rot/min), the main
crystal frequency for the floppy disk controller is 8.333 MHz
(not 8 MHz, as in 1050, for example)."
2. If the PC drive is a 1.2M drive there is the additional problem of the
track width.
The following is generally true in the PC world:
- disks written on 360k drives can be read on either drive
- blank disk formatted and written on 1.2M drives can be read on
either kind
- disks written on a 360k drive, and overwritten on a 1.2M drive,
can be read reliably only on a 1.2M drive.
- disks previously formatted on a 360k drive, or formatted as 1.2MB,
and then reformatted on a 1.2M drive to 360k, can be read reliably
only on a 1.2M drive.
(all this assumes you are using DD media, not HD).
Solution: Use a 360k drive if you can. If not, format disks on the
Atari for Atari to PC transfers, format truly blank disks on the PC
for PC to Atari transfers.
Jon D. Melbo sums it up this way:
So a basic rule of thumb when sharing 360KB floppies among 360KB &
1.2MB drives is: Never do any writes with a 1.2MB drive to a disk that
has been previously written to in a 360KB drive....UNLESS... you only
plan on ever using that disk in the 1.2Mb drive from then on out. Of
course a disk can be reformated in a particular drive any time for use
in that drive. As long as you follow that rule, you can utilize the
backwards compatible 360KB modes that most 1.2MB drives offer.
While the above mentioned utilities work with SS/DD 180K Atari-format disks or
SS/DD 180K SpartaDOS disks, the following combination of utilities has been
used successfully to read SS/SD 90K Atari-format disks. So if you only have
standard Atari 810 and/or Atari 1050 drives, you could look into:
AnaDisk -- now a product of New Technoligies Inc. (NTI)

Available: http://ch.twi.tudelft.nl/~sidney/atari/
- converts AnaDisk dump files from Atari format
See http://ch.twi.tudelft.nl/~sidney/atari/ for tips on using this
combination of utilities.
Preston Crow writes:
"As best as I can figure it out, if your PC drive happens to read
FM disks (I'm not sure what the criteria for that is), then you
can read single density disks on your PC by dumping the contents
to a file with AnaDisk, and then using Deana.com to convert the
dump file into a usable format.
For enhanced density disks, Anadisk generally only reads the first
portion of each sector, but it demonstrates that it is possible for
a PC drive to read enhanced density disks."

Subject: 10.5) How do I transfer files using a null modem cable?
This section by Russ Gilbert.
Q: How do I connect two computers using a null modem cable?
A: You need a term program and RS-232 ports on both
computers. The RS-232 ports need to be connected
together using a 'null modem cable'.
For up to 4800 baud, no flow control lines need be
connected. Just cross the transmit and receive lines
and join the grounds together. Transmit is pin #2,
receive is pin #3 and ground is pin #7 on the 25 pin
port. 25 pin #2 goes to Atari #4 (XMT to RCV), 25 pin
#3 goes to #3 on Atari (RCV to XMT) and #5 of 850 goes
to #7 of 25 pin (GND to GND).
The right hand pin on the 'long' side of a female 'D'
connector is #1. There are 13 holes on this 'long'
side, 12 holes on the 'short' side. The numbers go
to the left 1 to 13 then #14 is under #1 and left again
so that #25 is under #13.
Most term programs allow a null connection, without a
carrier detect. Notably, '850 Express!' does not. I have
only used 'Procomm 2.4.3' (the last shareware version of
Procomm) on the PC and BobTerm on the Atari, but other
term programs may work.
To check your null modem connection, start both PC and
Atari term programs, set baud to 2400 or 4800 on both
computers. No parity, 8 data bits, 1 stop bit on the PC.
Be sure to use the correct COM port on the PC. Go to
'terminal' mode and you should now be able to type on
either computer and see it on the other screen. To
accomplish a file transfer, use Y-modem probably from
BobTerm, rather than X-modem. X-modem will often append
bytes to a file transfer, an undesirable event. There is
also a very nice Z-modem recieve program for the Atari,
called ATAR-Z-MODEM by Larry Black for the Atari.
A convenient way to make a null modem cable, up to about
30 feet long, is to use two female DB25 connectors
(Radio Shack) some three or more conductor cable. Using
the two DB25 female connectors allows unplugging your
modems and plugging in the null modem cable into the two
modem cables. This also avoids the confusion of
variations in the computer ports. Most computers connect
into the modem end via a standard RS-232 DB25 connection.
With this both ends 25 pin cable, you would cross pins 2
and 3 and connect the #7s together to make a null modem
cable.
The SIO port on the Atari cannot be used directly. An
850, P:R: Connection, MIO, Black Box or similar device
that provides an RS-232 port must be used.
Following are pin assignments for a DB25 pin RS-232-C
port.
1. Protective Ground 12. Select Alternate Rate
2. Transmit Data 15. Transmit Clock (sync)
3. Receive Data 17. Receive clock (sync)
4. RTS (Request to Send) 20. Data Terminal Ready
5. CTS (Clear to Send) 22. Ring indicator
6. Data Set Ready 23. Select Alternate Rate
7. Signal Ground 24. Transmit Clock
8. Carrier Detect
For higher speed connections, above 4800 or 9600, you
need the flow control lines and Atari term software that
has flow control built in. You also need an MIO or Black
Box, which uses the PBI (parallel bus). A high speed
cable would need not only XMT, RCV, and GND, but also
flow control lines. I suggest a commercial null modem
from computer store to ensure correct lines. A null
modem is a small adapter with the correct lines already
crossed. I don't know how to correctly connect the CTS,
RTS, DTR, DSR, CRX lines for a high speed null modem.
With a null modem, you just plug it into the 25 pin
connectors of the two modem cables you might already
have connected to your Atari and PC or Mac. You may need
a straight thru 25 pin gender changer also.
Following is in this FAQ elsewhere, but I summarize here:
(Figure out or look for pin numbers on the ports.) Note
that these are pin assignments, and NOT null modem
connections with the XMT, RCV crossed and GND straight
thru.
Atari 8-bit PC AT 25 PC AT 9 pin
-------------------------------------
1. DTR 20 4*
2. CRX 8 1*
3. XMT 2 3

5. GND 7 5
6. DSR 6 6
7. RTS 4 7
8. CTS 5 8
9. No connect? shield RI
22 RI
Note: * above indicates the difference between an AT 9 pin
and a Atari 8-bit 9 pin cable connector. eg. If you check
continuity from pin 3 of 25 pin end and it goes to pin
4 of nine pin end, you have an Atari serial cable. If pin
3 of 25 pin goes to pin 2 of 9 pin end, you have a PC
serial cable.

1973
With financial support from Atari, a group of engineers led by Larry Emmons
and Steve Mayer created the Cyan Engineering research and development group in
Grass Valley, CA.
1974
Winter: Atari started an exclusive relationship with Cyan Engineering, and the
facility became known as the "Grass Valley Think Tank."
1975
Summer: At Cyan Engineering, Ron Milner and Steve Mayer created the first
concept prototype of the home video game system that would become the Video
Computer System (VCS). The hardware was built by Milner.
December: Joe Decuir was hired by Atari, initially to work with Ron Milner and
Steve Mayer at Cyan Engineering. Decuir would help debug the existing concept
prototype of the VCS, and Decuir built the first gate-level prototype of the
VCS.
1976
March: As Atari VCS development continued, Joe Decuir moved to Los Gatos,
Calif. to apprentice for Jay Miner, who would become the lead chip designer
for the VCS.
The group who would turn out to be the key engineers of the Atari VCS had now
been assembled: Steve Mayer, Ron Milner, Joe Decuir, and Jay Miner.
Development work would continue into 1977.
Fall: Atari purchased Cyan Engineering outright, and the facility became more
formerly known as the Grass Valley Research Center.
1977
June: Atari introduced the Video Computer System (VCS) at the Summer CES in
Chicago.
Summer: Engineers Ron Milner, Steve Mayer, and Joe Decuir, veteran designers
of the VCS, began work on a next-generation home video game machine at Atari's
Grass Valley Research Center. This project became known as "Oz" inside Atari.
1978
March: Manny Gerard at Warner Communications arranged for Raymond E. Kassar,
who had recently departed from his executive vice president position at fabric
maker Burlington Industries, to work with Atari as a consultant.
Gerard then had Kassar installed as president of Atari's Consumer Division.
Ray Kassar, directed that the video game technology already under development
as the "Oz" project would now form the basis for the development of a personal
computer system. The newly-redefined project become known as "Colleen" inside
Atari.
The overall engineering plans for "Colleen" were conceived by:
Steve Mayer, Joe Decuir, and Jay Miner
The "Colleen" computer project evolved into two specific computer models:
o "Colleen" - the full-powered machine - would be released as the Atari 800.
o "Candy" - the lower-end machine - would be released as the Atari 400.
Fall: Atari pre-announced that the Atari computer would debut at the January
1979 CES. [EVIDENCE NEEDED!]
September/October: Atari VCS game programmers David Crane, Larry Kaplan, and
Alan Miller were assigned to create an Operating System and BASIC for the
Atari computer, after Jay Miner, manager of both custom chip and OS software
development for the computer, had determined that both the existing work-in-
progress OS and the work-in-progress port of Microsoft BASIC could not meet
the January 1979 CES deadline.
October: Freeing Crane/Kaplan/Miller to focus on developing the core OS, Atari
contracted with Shepardson Microsystems, Inc. (SMI, headed by Bob Shepardson)
to create both a version of BASIC and a File Management System (FMS) for the
upcoming Atari personal computers.
November: At the Warner Communications annual budget meeting in New York,
Atari chairman Nolan Bushnell warned against launching an Atari computer
division unless Warner was prepared to absorb extensive short-term financial
losses in establishing the new product line. Bushnell also predicted that a
properly-funded Atari computer line would ultimately be profitable.
December: Manny Gerard at Warner Communications appointed Ray Kassar President
and CEO of Atari, and Joe Keenan replaced company founder Nolan Bushnell as
Chairman.

1985
January 5: Atari introduced the 65XE and 130XE home computers at the Winter
CES in Las Vegas. (The 65XEP and 65XEM computers were announced, but these
never made it into production.) The 800XL would be discontinued. XE
peripherals introduced: the XMM801 and XDM121 printers and the XM301 modem.

renamed Music Painter), The Learning Phone (PLATO). (Also introduced but
never shipped: the XTM201 and XTC201 printers, the XC1411 and XM128 monitors,
and the XF521 disk drive. XE Software: Infinity (integrated word processor/
spreadsheet/database/telecomm software, developed for Atari by Matrix
Software / Vincent Garafolo), Shopkeeper, Atari Tutorial.
Epyx introduced Ballblazer and Rescue on Fractalus for the Atari 8-bit
computers, both announced but not shipped by the old Atari, Inc.

March 5: At the San Leandro Computer Club Atari announced that they had
"postponed plans to produce an 8-bit portable computer, due to lack of
interest." Also, "plans for an XEM 8-bit music computer have been postponed
indefinitely due to problems with finalizing the AMY sound chip." (The AMY
chip had been developed at Atari, Inc. Atari Corp. now owned the technology,
but had not retained the original design team. Thus, the new plan to
integrate AMY into the XE system, as the announced 65XEM computer, turned out
to be prohibitively expensive. Atari ultimately sold the AMY chip and
technologies to a Milwaukee based audio design house called Sight & Sound.
