		Colossus Chess, the series of chess programs by Martin Bryant developed from 1983 on an Apple II in 6502 Assembly, based on Bryant's former program White Knight. Colossus Chess 2.0 was the first commercial release in 1884 for the Commodore 64 and this and subsequent versions for other 6502, Z80, 68000 and 8086 based home and personal computers, such as Atari 8-bit, BBC Micro, Amstrad CPC, ZX Spectrum, Atari ST, Amiga, and finally for the IBM PC. Colossus Chess pioneered a sophisticated GUI with an optional 3D chessboard, and lot of new features for that time, and has become one of the best selling chess programs of all time ^[1]. Colossus Chess played the European MCC 1983 in London and the WMCCC 1984 in Glasgow.
