Perhaps I read it wrong but the PONGMECHANIK uses logic to determine when
the ball has hit a paddle or wall.

"Element 2: The movements of ball and racquet, as well as the collision
detection take place in a metal chassis under the glass cover. Each moving
game compoent has a mechanical counterpart, which is moved by electric
motors. When these parts collide, contacts are closed and the relays in
the computer switch the direction of rotation of the motors."
