The Atari 8-bit computer is a family of 8-bit computers developed and sold by Atari. The line began in 1979 with the simultaneous release of the 400 and 800. The 400 had weaker specs and was sold as a gaming computer while the more powerful 800 was marketed as an office computer. Later models followed including the XL series and XE series. Although each new computer was an update to the previous, software for the computers is mostly backward-compatible and the vast majority of the software library will work on the Atari 400.
The Atari 8-bit series released several models.

Music and Sound
Each of the Atari 8-bit computers had an on-board C012294 chip, known as the POKEY (Pot Keyboard). This chip handled the computers I/O including the keyboard and paddle controllers, but also housed the computer's audio processing unit (APU). The POKEY featured 4 square wave channels, each could produce and independent frequency, volume, and noise level.
