The 75 MHz Performa 5200 was the first PowerPC Mac with an integrated monitor. Although the PPC 603 CPU was superior to the older 601, this computer’s architecture kept performance of the 5200 – and it’s monitor-less twin, the 6200 – comparable to a 66 MHz Power Mac 6100.
To save money, Apple based the motherboard on the Quadra 605 with its 25 MHz bus and 32-bit memory, even though the 603 is a 64-bit chip. Apple also used an 8-bit IDE controller for the hard drive. This is the kind of thinking that had crippled the LC with a 32-bit CPU on a 16-bit bus in 1990.
Because of unusual architecture, installing a 25-pin SCSI terminator to the SCSI port (if you have no SCSI devices attached) will improve network stability.
Open Transport 1.2, which ships with Mac OS 8, solves many network problems.
If you are using a serial printer and no modem, connect the printer to the modem port to avoid network problems.
A word of warning: the serial ports don’t support hardware handshaking, which is required for all modems 9600 bps and faster. You must use a comm slot modem for good throughput.
FWB HD Toolkit is a much better driver for the IDE hard drive than Apple’s.
Be sure to read Performa and Power Mac 5200, 5300, 6200, 6300 Issues. Then you’ll understand why it’s called a Road Apple – we consider it the worst Mac hardware ever.

- 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.
- On most models, the serial ports do not support hardware handshaking necessary for high speed (9600 bps or higher) modems. However, Global Village Teleport Platinum modems implement handshaking on the modem, providing 28.8 kbps and faster telecommunications. (The final revision of the motherboard does support hardware handshaking.)
