Power Mac 7300

The Power Mac 7300 is pretty much the same computer as the 7600, except that it has a faster CPU and a special cover that makes it harder to dismantle the case (important in settings where users might steal memory, drives, etc.).

Power Mac 7500The 7300 seems to be the only time Apple has improved a computer and given it a lower model number. This may be due to removing the video in capability.

The 7300 was part of the last generation of Macs to ship with a SCSI hard drive as a standard feature.

The 7300 was replaced by the much more powerful beige Power Mac G3 in November 1997.

Cautions

  • Because of the way the internal SCSI cable is routed in the 7300-7600, it is very easy for it to come loose from the motherboard while opening the case. Should this happen, be sure to plug it back into SCSI bus 0, not SCSI bus 1 (which is for the slower external SCSI port).
