Sargon (chess)
Sargon was inspired by a BASIC listing of an unfinished chess program that the Spracklens found around 1977. They decided to create such a program themselves. They chose to make the program in assembly language. This was because it was much more efficient. They also used the 8-bit Z80 microprocessor that the American company Zilog just started selling. The first version was released in 1978. In that same year they won the March 3 - 5 Computer Chess Tournament in San Jose, California West Coast Computer Faire .
