The Gamma was a machine designed by Microbee Systems Ltd in Australia between 1985 & 1987. It was an advanced machine based on the Motorola MC68000 and was designed for true multitasking with a full memory management unit built in.
The machine was Microbee's equivalent to the Apple Mac, Atari 520ST and the Commodore Amiga.
Unfortunately, only 20 were ever built.
Along with the 68000 (running at 8Mhz) there were 2 Z80's - one to run CP/M-80 & provide some backwards compatibility with older models, and the other to handle DMA & other programmed special functions.
The Screen display had one of the highest resolutions available (720 x 350 pix )at that time, with full 16 colour (out of a palette of 4096) bit plane graphics.
It had 8 bit mono sound with hardware FIFO, 2 SCC channels for serial comms & networking, Parallel I/O & mouse port.
It was also designed with an expansion buss that would accept a 80186 Processor card for PC-DOS operation.
