The Gemini Challenger was a Motorola 68000 based computer, released in 1985 and designed by Gemini Microcomputers based in Chesham.[1][2][3] This was Gemini's first non Z80 computer and their last.[4]
It was designed to look like an ordinary PC-compatible computer, with a Wyse WY-50 remote terminal for monitor.[2] Four operating systems were available (MBOS, aimed for business and supporting multiuser; Mirage, another multiuser OS; TDI p-System, a version of UCSD p-System including Pascal; CP/M 68k), along with an advanced optional graphic card (based on the Hitachi HD63484) with a maximum resolution of 1024 x 1024 pixels and 16 million available colours.[2]
