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.
