An image from Atari's original patent application for its "video game control unit"

The folks over at Technologizer have put together a gallery of images taken from patent applications for electronic gaming systems ranging from the original Television Gaming Apparatus in 1969 to the Nintendo Game Boy in 1989. The text of the applications is rather geeky, but the images therein make for memory-prompting journey through our not-too-long-ago interactive past. Enjoy.
