General Information

The Atari 7800 is a video game console released by Atari Corporation in June 1986. A test market release had occurred two years earlier under Atari Inc. The 7800 was designed to replace Atari Inc.'s unsuccessful Atari 5200 and later to re-establish Atari Corp.'s market supremacy against Nintendo and Sega. With this system, Atari Inc. addressed all the shortcomings of the Atari 5200: it had simple digital joysticks; it was almost fully backward-compatible with the Atari 2600; and it was affordable (originally priced at $140).
The Atari 7800 Prosystem was the first game system from Atari Inc. designed by an outside company, General Computer Corporation (GCC). The system had been designed in 1983 and 1984 with an intended mass market rollout at the end of 1984. The project was originally called the 3600 and then later renamed the 7800.
Several key factors influenced the design of the 7800. First, Atari had been facing mounting pressure from the Colecovision, which boasted graphics that more closely mirrored arcade games of the time than Atari’s reigning 2600 VCS system. Second, the Atari 5200 (the original intended successor to the Atari 2600 VCS) had been widely criticized for not being able to play Atari 2600 VCS games and for the poor quality of its analog joysticks. Finally, dropping prices of home computers like the Commodore 64 had caused many parents to believe that buying a home computer was a better investment because it provided more detailed game play and could be used for other purposes such as word processing.
