MicroBee (Micro Bee) was a series of home computers by Applied Technology, later known as MicroBee Systems.

The original MicroBee computer was designed in Australia by a team including Owen Hill and Matthew Starr. It was based on features available on the DG-Z80 and DG-640 S-100 cards developed by David Griffiths, TCT-PCG S-100 card developed by TCT Micro Design and MW6545 S-100 card developed by Dr John Wilmshurst. It was originally packaged as a two board unit, with the lower "main board" containing the keyboard, Zilog Z80 microprocessor, Synertek 6545 CRT controller, 2K of "screen" RAM, 2K of character ROM (128 characters) and 2K of PCG (Programmable Character Graphics) RAM (128 characters). Each byte in the screen RAM addressed a character in either the character ROM or PCG RAM. A second board, termed the "core board", contained the memory, and on later models also included a floppy disk controller.
