Chess 0.5

In 1978 Larry Atkin wrote a didactic program in Pascal along with Peter W. Frey, which was published as Chess 0.5 in the Byte Magazine ^[6], and re-published on-line in 2005, available from Scott A. Moore's sites ^[7][8].

In the '80s Larry Atkin worked for Applied Concepts on dedicated chess computers and is mentioned along with David Slate as co-author of the Gruenfeld and Capablanca module programs for the Great Game Machine and the Chafitz modular game system . He is further sole author of the Steinitz Edition 4 ^{[9] [10]}, and the Steinitz Encore ^[11], both running on a 8-bit 6502 processor with 2 resp. 4 Mhz. Capablanca was later converted to be Chess 7.0 for the Apple II, Atari 800, and Commodore 64 published by Odesta. Even later it became "How About a Nice Game of Chess" for the Apple IIe ^{[12] [13]}.
