Computer released by Atari in 1985. Enjoyed almost ten years of success thanks to some amazing games and productivity software. Many musicians started out using Cubase on the Atari ST, thanks to its built-in MIDI support. Was available with 0.5 or 1 MB of RAM and was expandable to 4MB. There were many aftermarket hard drive adaptors and accelerators.

Atari ceased production of the ST in 1994 to concentrate on the Jaguar console instead.
