Clash,
a chess program written in Fortran IV by Chris Peters, in 1980 a student at the University of Washington. Clash played the ACM 1980 on a Texas Instruments TI-990 16-bit minicomputer (28k, 16 bits; 200,000 inst/sec). Without iterative deepening there was not much to gain, and Clash lost all of its four games.

Description

A brief description is available from the ACM 1980 tournament booklet [2] :

Clash is entering its first ACM tournament. The program is written in Fortran IV by Chris Peters, a student at the University of Washington. It requires 10k for instructions and an additional 4k for the tree search. The program searches a highly selective tree and examines about 1,000 - 2,000 positions per move. It uses the alpha-beta algorithm and the killer heuristic but does not employ iterative deepening.
