Discontinued01st January 1992

The Atari 7800 ProSystem was developed for Atari by General Computer Corporation (developers of the arcade games Ms. Pacman and Food Fight). Originally set for launch in 1984, the sale of Atari to Jack Tramiel and contractual issues with GCC, led to the 7800 not seeing the light until 1986.

Although only 59 games were released for the system in its lifetime, it could also play Atari 2600 games, giving it access to a much huger library.
