Macintosh Centris 660AV

The Macintosh Quadra 660AV (Codename: "Tempest") is a personal computer that is a part of Apple Computer's Quadra series of Macintosh computers. When it was originally introduced in July 1993 alongside the Quadra 840 AV it was called the Macintosh Centris 660AV, but it was renamed without any major changes in the hardware when the Centris line was abandoned in October 1993. It was discontinued in September 1994, with no immediate replacement - however, the AV versions of the Power Macintosh 6100 that had already been introduced had a very similar position in Apple's product lineup.
