The Atari 7800 ProSystem, or simply the Atari 7800, is a home video game console officially released by Atari Corporation in 1986 as the successor to both the Atari 2600 and Atari 5200.[3] It can run almost all Atari 2600 cartridges, making it one of the first consoles with backward compatibility. It shipped with a different joystick than the 2600-standard CX40 and included Pole Position II as the pack-in game.
