Introduced in August 1995, The 8500 brought 604 power and the PCI architecture to the mid-range, also boasting impressive AV features. The 8500 included a 120 Mhz 604 processor and 24-bit composite and S-video input and output. The processor of the 8500 shipped on a removable daughtercard. The 8500 came in a mini-tower case, sold for $4000, and was "speed bumped" to 132 and 150 Mhz in April 1996. It was speed bumped again to a 180 Mhz 604e processor in August, and was replaced in early 1997 by the 8600.

'''Note:''' These computers do not have any main memory soldered to the logic board. At least one RAM DIMM must be present for the computers to operate. DRAM DIMMs can be installed individually; however, if you wish to take advantage of the computer’s interleaving capability, which provides maximum performance, you must install the DIMMs in matching pairs and in paired slots (A4 and B4, A3 and B3, and so on).

===PCI===
The Power Macintosh 7500 and 8500 computers have three expansion slots using the industry standard PCI bus. The PCI bus is a nonsplit bus with 32-bit multiplexed address and data. The PCI expansion slots in these computers use a 33 MHz system clock. The Power Macintosh 7500 and 8500 computers accept standard PCI cards as defined by the PCI Local Bus Specification, Revision 2.0. The cards are required to use the 5 V signaling standard and to use the standard ISA fence described in the specification. Each computer provides a total of 50 W of power for its three expansion slots. Both 5 V and 3.3 V are supplied; the total power at both voltages must not exceed the 50 W maximum.
