Apple Macintosh Quadra 660AV

Apple Macintosh Quadra 660AV was introduced in 29 July 1993 as the compact member of Apple's first AudioVision multimedia pair. It used a Motorola 68040 at 25 MHz with AT&T 3210 DSP with 8MB standard; expandable to 68MB. AT&T DSP accelerated audio and telecommunications functions.

It brought DSP-assisted audio, speech and desktop-video facilities to a lower-cost enclosure than the flagship 840AV.

Notable Features

• AT&T DSP accelerated audio and telecommunications functions.
• Composite and S-video input/output enabled desktop-video capture.
• GeoPort-capable serial hardware anticipated software-based communications.

Historical Significance

• It brought DSP-assisted audio, speech and desktop-video facilities to a lower-cost enclosure than the flagship 840AV.
• Its place in the range reflects Apple's progression from the original compact Macintosh toward broader professional, educational and portable markets.

Collector’s Notes

• Original AV cables and intact rear multimedia connectors are particularly desirable
• Original keyboards, mice, storage devices and model-specific accessories help document a complete period configuration.
