The Gemini Galaxy range of computers were of "all British" origin, being manufactured by Gemini Microcomputers Ltd., Amersham, Bucks.
|
|
|
|
Also called the 'Multiboard Microsystem', the Galaxy systems were built around the 80-BUS, specifically designed for the Z80 microprocessor. They had two Z80A processors, one acting as the CPU and the other running the 'programmable' video card (Called the IVC).
|
|
|
|
The video card memory was composed of: 2 KB Monitor ROM (SIMON), 2KB User workspace RAM (it was capable of holding user routines), 2 KB Screen RAM, 2KB character generator ROM, 2KB character generator RAM (programmable fonts). Numerous cards were available, like IEEE488 interface card, SASI floppy drive controller or colour graphics card.
