The Atari TT030, more commonly known as the Atari TT, is a member of the Atari ST family, released in 1990. It was originally intended to be a high-end Unix workstation, but Atari took two years to release a port of Unix SVR4 for the TT, which prevented the TT from ever being seriously considered in its intended market.

In 1992, the TT was replaced by the Atari Falcon,
