The Atari Game Brain (Model C-700) is an unreleased dedicated home video game console that was supposed to be released by Atari in June 1978.
It plays 10 particular games, ported from all of Ataris previously released dedicated consoles, such as Pong, Stunt Cycle, and Video Pinball.
Its controllers were built onto the system, with 4 directional buttons, a paddle, and a fire button. Games are inserted in the top of the system by opening a door that also bears a small instruction booklet.
The system was not intended as a big seller for Atari but rather as a clearance of CPUs from unsold dedicated consoles.
By the time the Game Brain was finished, dedicated consoles were becoming obsolete against consoles with removable ROM cartridges, such as the already released Fairchild Channel F, the RCA Studio 2, and Ataris own Atari 2600.
Atari cancelled the Game Brain around 1978.
Three Atari Game Brain consoles and five prototype cartridges are known to exist.
