) in/out ports not found in the 9500. In fact, the 8500 incorporated near-broadcast quality (640Ă—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

The Power Macintosh 7200 (and Power Macintosh 8200 tower based variant which was available alongside the 7200 in Europe) is a personal computer designed, manufactured, and sold by Apple Computer from August 1995 to February 1997. The 90 MHz mo ...

Apple referred to these machines collectively as the "Power Surge" line, communicating that these machines offered a significant speed improvement over its predecessors. Infoworld Magazine's review of the 8500 showed a performance improvement in their "business applications suite" from 10 minutes with the 8100/100, to 7:37 for the 8500/120.
They also noted that the 8500 run an average of 24 to 44 percent faster than a similarly clocked
