Ping-O-Tronic

The Ping-O-Tronic has over fifty transistors and twenty diodes and three TTL chips (7400 type). All of the graphic objects (paddles, ball, boundaries) and sync signals are generated by transistor flip-flops and one-shots. The chips combine the individual signals so as to manage events like collisions between the ball and a paddle, or a lost ball. They may also be used as triggers for the serves.
