The Power Macintosh 8500/150 represented a speed bump for an already existing Macintosh model. Part of the second generation PowerMac family it was released in the spring of 96 when there was a great deal of competition from the then existing Macintosh clone makers, such as Power Computing. The 8500 was considered a good, if expensive, performer and was a mid-level machine aimed at in-house publishing, media authoring and technical market segments. It distinguished itself from other machines in its class by having near broadcast quality video circuitry built-in. The machine is capable of 24-bit video input/output and has both composite and s-video connectors. The 8500/150 sports a 604 PowerPC processor which was the fastest PowerPC processor at that time. The 604 processor would last only a relatively short time, to become replaced in successor machines by the 604e. The 8500's processor resides on a separate daughter card making it easily upgradable to a faster processor. The machine sports 3 PCI slots, an extra drive bay (internal Fast SCSI - 10MBps) and 8 memory slots for a total possible capacity of 512MB of RAM. The 8500 shipped with 2MB of video RAM , the ability to add 2 more and also with an 256K L2 cache.
