A site celebrating the 40th anniversary of the invention of Pong, pongmuseum.com, has opened. With the museum comes a rare gem: a video directly from inventor Ralph H. Baer featuring himself and chief engineer Bill Harrison playing a demonstration model of their invention in 1971.

In addition to explaining the origin of the home video game console (which even goes into the basic schematics of the General Instrument AY-3-8500 chip, the common "pong" chip), Pong Museum includes a collection of international pong machines, from the breakthrough Magnavox Odyssey to the rare Heathkit GD that required users to open up their TVs to connect the game's wires directly.
