The Luxor ABC 800 series were office-versions of the ABC 80 home computer. They featured an enhanced BASIC interpreter, a slighly faster clocked CPU and more memory: 32 KB RAM was now standard, the Z80 was clocked at 3.58 MHz (using an NTSC color subcarrier crystal) and they could also be extended with "high" resolution graphics (240x240 pixels).
The ABC 800 came in a monochrome version with an 80 character wide screen, and a color version with 40 characters. The later ABC 806 had more memory and improved graphics, and the ABC 802 was compact version with the main board integrated with the small screen (where the ABC 80 and 800 has the main board integrated with the keyboard and a separate screen). It had no high-resolution graphics.
Storage was usually two 5.25" floppy disk units in 160, 320 or 640 KB capacity. External hard disk systems became available later (primarily the ABC 850, 10 MB). Model numbers 'ABC 800 M' for monochrome and 'ABC 800 C' for color.
"Who needs IBM-compatibility?", asked Luxor's adverts. However, most computer buyers eventually considered it a requirement. A certain compatibility could be achieved between the ABC-world and the PC-world with the help of a program called 'W ABC'.
The ABC 800 computer was also sold by Facit by the name Facit DTC.
