Draughts

Draughts © 1951 Strachey, Christopher.

Draughts is a simulation of the game checkers. The player could play against the computer whose moves were recorded on a teletype printer. The player had to use switches to select his move. There were two cathode ray displays showing the current state of the game and the current input. The input could be discarded if it was undesired. When the program terminated it played God Save the King through the mainframe's speaker.
