> Pongmechanik is an electromechanical version of the early digital tennis game Pong. It uses computer technology of the 1940's to implement a computer application of the 1970's. The control logic of the game is entirely built out of telephone relays, the same parts that the first digital computers used, which were built by pioneers like Konrad Zuse.
