The Atari 7800 ProSystem, or simply the Atari 7800, is a home video game console officially released by Atari Corporation in 1986. It is almost fully backward-compatible with the Atari 2600, the first console to have backward compatibility without the use of additional modules. It was considered affordable at a price of US$140. The 7800 has significantly improved graphics hardware over the 2600, but uses the same audio chip. It also shipped with a different model of joystick than the 2600-standard CX40.
