Coko – Mainframe – 1970

Coko (the Cooper-Kozdrowicki chess program) is a chess program written in FORTRAN. It plays a minimal chess game at the rate of 0.2 sec CPU time per move, with a level close to lower chess club play. It participated in four American computer chess championships (1970, 1971, 1972 and 1973). Later versions included the Mater software which is a dedicated piece of software to detect check-mate situations: both how to cause them and how to prevent them.
