The Nimatron was an electro-mechanical machine that played Nim. It was first exhibited in April–October 1940 by the Westinghouse Electric Corporation at the 1939-1940 New York World's Fair to entertain fair-goers. Conceived of some months prior by Edward Condon and built by Gerald L. Tawney and Willard A. Derr, the device was a non-programmable digital computer composed of electro-mechanical relays which could respond to players' choices in the game in a dozen different patterns. Wikipedia.
