The Atari 5200 SuperSystem, commonly known as the Atari 5200, is a video game console that was introduced in 1982 by Atari Inc. as a higher end complementary console for the popular Atari 2600.

Actual working Atari Video System X machines, whose hardware is 100 % identical to the Atari 5200 do exist, but are extremely rare.

The Atari 7800 ProSystem, or simply the Atari 7800, is a video game console re-released by Atari Corporation in January 1986.

This advanced programming technique is documented in the original 1983 " Atari 3600 Software Guide ".

A common criticism of the 7800 regards its use of the TIA to provide 2-channel sound effects and music, resulting in sound quality that is virtually identical to the Atari 2600 VCS from 1977.

The most substantial difference, however, is a graphics architecture which differs markedly from either the Atari 2600 VCS or Atari ’ s 8-bit line of computers.

The 7800's compatibility with the Atari 2600 is made possible by including many of the same chips used in the Atari 2600.

When in “ 7800 ” mode ( signified by the appearance of the full screen Atari logo ), the graphics are generated entirely by the MARIA graphics processing unit, all system RAM is available and game data is accessed in larger 48K blocks.

A more recent development is the Atari 7800 expansion module developed by Legacy Engineering with a high scores save feature ( with compatible games ), additional RAM capabilities, as well as vastly improved sound capabilities using the POKEY and YM2151 sound chips.
