Note: The Atari 7800 was originally intended to come out in the fall of 1984, and a test market launch was planned for the summer. Due to Warner selling the Atari home division to the Tramiel family and the subsequent argument over who owed GCC the money for the system and its games, the machine did not actually launch until 1986. It does not appear that any units or games were sold in 1984; most likely any extant copies with the 1984 branding were stock that went out in 1986.
1986
The Atari 7800 started hitting stores in May 1986, with Pole Position II as a pack-in title.
