That Pac-Man was Namco, not Atari.
It was insane how many people got that wrong in a thread a while back. It was even more insane that the Atari port for Pac-Man was absolutely terrible, and one of the worst ports ever made.
Also, video/Computer gaming is actually a lot older, than most people think. Most Gamers think that the 1972 game pong was the first digital game, it wasn't. The first modern digital game Space War was created in 1962 on the PDP-1 machine, which only one is in existence today. Gaming history can been traced even further back than that, with tennis for two, a simple pong like game, and OXO that was created in the 50's using a cathode ray tube.
This is a picture of the machine used for such a monstrous task.
The first game console came out in 1972 called the Magnavox odyssey, it had hardly any graphics to speak of, so it had overlays to compensate.
Space age technology for a space age time.
