The Atari ST.

Under Tramiel's ownership, Atari Corp. used the remaining stock of game console inventory to keep the company afloat while they finished development on a 16/32-bit computer system, the Atari ST. ("ST" stands for "sixteen/thirty-two", referring to the machines' 16-bit bus and 32-bit processor core). In April 1985, they released the first update to the 8-bit computer line — the Atari 65XE, the Atari XE series. June 1985 saw the release of the Atari 130XE; Atari User Groups received early sneak-preview samples of the new Atari 520ST's, and major retailer shipments hit store shelves in September 1985 of Atari's new 32-bit Atari ST computers.
