Pong: The Electro-mechanical Version

(The below snippet is from the website, don't blame me for the funky sentence structure.)

"Pongmechanik is an electromechanical conversion of the classical game Pong. And instead of more realistic graphics, it ever accurately to reproduces the original Pong. The user is hardly changed. However the game breaks open the Black box: What takes place in the computer, becomes again perceptible and comprehensible."
