Apple PowerMac 8500 (1995)
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 (640ร480) 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.
