Genre: Board game

Board games were among the earliest projects on the Atari 2600, and chess was the hardest of them to fit on a cartridge. The site’s board game category currently holds one title: Computer Chess, an unreleased 1978 Atari prototype by Bob Whitehead and Larry Wagner. It is the longer early version of the program that Atari trimmed down and sold in 1979 as Video Chess, and it still has rough edges, such as no pawn promotion and no check warnings.
