Microchess
From Wikipedia, the free encyclopedia
Microchess, by Peter R. Jennings, was originally a microcomputer Chess Program for the MOS Technology Kim-1 microcomputer. What made it remarkable was the Kim-1 had a 6502 and only 1 kibibyte of memory, and only a hex keyboard and tiny segment display, yet the program played passable chess.
Microchess was later expanded into a fuller program with graphics for the Commodore PET, Apple II and Atari 400/800 computers. It was the first microcomputer software package to sell 50,000 copies, at the time, almostly exclusively on cassette tape. Jennings founded VisiCorp together with Dan Flystra, and the new company published Microchess to the growing microcomputer market. Microchess gave the company enough success to launch VisiCalc which would be its greatest success.
