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

, 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. 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

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.
