The Macintosh Quadra 660AV, originally sold as the Macintosh Centris 660AV, is a personal computer designed, manufactured and sold by Apple Computer from July 1993 to September 1994. It was introduced alongside the Quadra 840AV; the "AV" after both model numbers signifies video input and output capabilities and enhanced audio. It was rebranded from Centris to Quadra in September 1993 without any actual internal changes.
The 660AV was discontinued a few months after the introduction of the Power Macintosh 6100/60AV. Apple sold a Power Macintosh Upgrade Card that upgrades the 660AV to match the 6100/60AV's specifications for US$1,399. This and the Quadra 630 were positioned for users who were not ready to move to PowerPC.
