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. It is able to run almost all Atari 2600 cartridges, making it the first console with built-in backward compatibility. It shipped with a different model of joystick from the 2600-standard CX40 and "Pole Position II" as the pack-in game. Most of the announced titles at launch were ports of 1980–83 arcade games.
