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 from the 2600-standard CX40.
The 1986 launch is sometimes referred to as a “re-release” or “relaunch” because the Atari 7800 had originally been announced on May 21, 1984, to replace Atari Inc.’s Atari 5200, but a general release was shelved due to the sale of the company.
On January 1, 1992, Atari Corp. officially dropped all remaining support of the 8-bit line.
