Description
The Macintosh Quadra 840AV (code names: "Quadra 1000", "Cyclone") is a personal computer that is a part of Apple Computer's Quadra series of Macintosh computers. It was introduced in July 1993 alongside the Centris 660AV, the "AV" after both model numbers signifying video input and output capabilities, as well as enhanced audio. It was discontinued in July 1994, with no immediate replacement – however, the later AV versions of the Power Macintosh 8100 took a very similar position in Apple's product lineup.
