The Macintosh Quadra 660AV (originally called the Macintosh Centris 660AV) is a personal computer designed, manufactured and sold by Apple Computer Inc. from July 1993 to September 1994. It was introduced alongside the Quadra 840AV. It was introduced alongside the Quadra 840AV, the "AV" after both model numbers signifying video input and output capabilities, as well as enhanced audio.

The 660AV was discontinued a few months after the introduction of the Power Macintosh 6100/60AV. Apple also sold a Power Macintosh Upgrade Card that upgraded the 660AV to match the 6100/60AV's specifications for $1,399 USD.[1]

Hardware[edit]

The 660AV uses the "pizza box" case of the earlier Centris 610. The 660AV has a full Motorola 68040 instead of the 610's FPU-less 68LC040.[2] Like the 840AV, the 660AV features video input/output capability and an onboard AT&T 3210 digital signal processor (here clocked at 55 MHz) to make the video handling less of a burden on the CPU.

Some of the earliest Centris 660AVs have the older 'auto-inject' floppy drive opening similar to the 610, but most of the Centris models and all of the Quadra models have a drive similar to the Power Macintosh 6100, lacking the ‘auto-inject’ feature. These models have a deep round indent at the center of the floppy drive slot to make it possible to insert the disk all the way.

The Quadra AV Macs introduced a new universal ROM (codenamed SuperMario) that would later be used in all PowerPC system. It includes SCSI Manager 4.3 and Sound Manager 3.0. It also is "vectorized" making it easier to patch. [3]
