Power Mac 4400 and 7220

The Power Mac 4400 (7220 in Australia) was Apple’s attempt to build an inexpensive Mac using more industry standard components, such as a chunky PC-like case. It was also available in a PC Compatible system with a 166 MHz DOS card with a 133 MHz Cyrix PR166+ 6×86 CPU (80486 class) and 16 MB RAM.

Power Mac 4400At first glance, you might think we flopped the photo of the 4400, but that’s not the case. This is the only Power Mac with its floppy drive on the left side.

The 4400 was Apple’s only computer designed around a modified Tanzania motherboard. The 4400 and other Tanzania-based clones will not boot with a dead PRAM battery. Try replacing the battery before attempting to replace the power supply on a “dead” 4400.

Overall, we have to label this one a compromised Mac.

Note that there are some significant differences between the 160 MHz and 200 MHz models in terms of memory capacity and expansion slots.

Cautions

  • Will not work with System 7.5.5
  • DIMM slot 1 supports only single-bank DIMMs.
  • Macs with IDE hard drive do not provide SCSI termination power, depending on external SCSI devices to provide it. For more details, see SCSI Termination Power.
