The Apple Power Macintosh 7220/200 (PC) was identical to the PowerMac 4400/200 (PC).
It was based on the Tanzania architecture co-developed by Apple and Motorola. The case is similar to a standard desktop PC, fabricated out of sheet steel. The 7220/200 shipped with System 7.5.3 as standard but could be user upgraded to OS 9.1. The use of the strange numbering convention for this Power Macintosh is purportedly due to the number 4 being considered “bad luck” in Asia, where it was marketed as the 7220.
Specs:
The Powermac 7220/200, features a 200 MHz PowerPC 603e processor, 16 or 32 MB of RAM, and a 1.2 GB or 2.0 GB hard drive in an industry-standard desktop case. The hard drive to this Powermac was ATA, replacing the SCSI system that had been employed in all previous Power Macintosh Computers up until this point. This cost saving measure also allowed users to considerably upgrade the storage capacity of the PowerMac. It was also the only Power Macintosh to employ an industry standard ATX power supply.
Officially this model supports 96 MB of RAM, but third-parties discovered that only the first slot is limited to a 32 MB single-bank memory module. The second and third slots can accommodate 64 MB memory modules for an actual total of 160 MB of RAM. Memory configurations should consist of 60 ns 168-pin DIMMs.
The 7220/200 includes one full-length 12-inch PCI slot and one 7″ PCI slot. However, in the PC Compatible configuration, the 12-inch PCI slot is occuiped by a 166 MHz Cyrix 6×86 PC compatibility card.
PC Compatability:
The PC-Compatible version ships with a 166 MHz Cyrix 6×86 processor card that can have up to 80 MB of RAM dedicated to the DOS/Windows operating system.
Ports & Connectivity:

As with all other Power Macintosh units, the 7220 provides a SCSI (25 pin) connector, ADB (Apple Desktop Bus), Printer Port (8 pin Mini Din), External Modem Port (8 Pin mini Din), DB 15 monitor port, Sound in and out ports (both 3.5mm jacks).
