The Atari 2900 is a true oddity in itself, never has any Atari document, engineering log, magazine article or word-of-mouth ever mentioned such a console.   Almost nothing is known about the console or its characteristics other then the basic mechanical features such as a clear plexiglass storage area for its controllers, 4 standard Atari 9-pin joystick ports, front power switch and what appears to be some sort of additional cartridge port or expansion port in the front right side of the console.   These photo's were graciously donated to the Atari Historical Society by former Atari Industrial designer William Renteria.
