Power Macintosh 8500

PowerPC 604e, 180 or 200 MHz

The Power Macintosh 8500 is a personal computer designed, manufactured and sold by Apple Computer from August 1995 to February 1997. Billed as a high-end graphics computer, the Power Macintosh 8500 was initially released with a 120 MHz PowerPC 604, and unlike earlier Power Macintosh machines, the CPU was mounted on an upgradeable daughtercard. Though slower than the 132 MHz Power Macintosh 9500, the first-generation 8500 featured several audio and video (S-Video and composite video) in/out ports not found in the 9500. In fact, the 8500 incorporated near-broadcast quality (640×480) A/V input and output and was the first personal computer to do so, but no hard drive manufactured in 1997 could sustain the 18 MB/s data rate required to capture video at that resolution. Later, special "AV" hard drives were made available that could delay thermal recalibration until after a write operation had completed. With special care to minimize fragmentation, these drives were able to keep up with the 8500's video circuitry.

The 8500 was introduced alongside the Power Macintosh 7200 and 7500 at the 1995 MacWorld Expo in Boston.{{cite magazine

The 8500's CPU was updated twice during its production run. It originally shipped with a 120 MHz PowerPC 604, later with the same chip running at 150 MHz, and finally with a PowerPC 604e running at 180 MHz. It was succeeded by the Power Macintosh 8600 in February 1997.
