PC on a CPU module means Primary Cache (ie. only on-die cache). SC means Secondary Cache (ie. L2 cache on the module).

RAM:

The Indy has 8 slots, taking 72pin parity RAM. 4 SIMMS per bank, 2 banks total, giving a maximum of 265mb.
Memory can be either 4mb, 8mb, 16mb or 32mb, and must be the same size and speed within a bank.

Graphics:

Indy's come with 3 main graphics options - 8bit XL, 24bit XL, and the XZ. The XL cards have decent 2D performance, but everything else is offloaded to the CPU. The XZ has some 3D acceleration (hardware Z buffer, geometry/lighting acceleration). However, it seems to be slower than the XL cards for 2D work.

Ports:

Lots of connectivity comes with the Indy as standard:

• ISDN BRI port

• PS/2 keyboard and mouse

• 10-BaseT or AUI ethernet

• External fast SCSI

• S-Video in

• Digital video in

• IndyCAM

• Sound (headphones, microphone, line-in, etc.)

• Bi-directional printer port

• 2 Mac-compatible serial ports

Drives:

The Indy has 2 internal 3.5 inch drive bays. These can either take the Floptical drive (SCSI drive that reads/writes normal floppies, and special 21mb 'floptical' disks) or normal hard drives.
If you want a CD or DAT drive, these can be connected via the external SCSI port - it is one SCSI channel though (unlike some other machines).

The internal SCSI connecters are 5mb/s SCSI-1. The cables for the hard drives are standard 50pin SCSI connectors. As SCSI as backwards compatible, any non-HVD drive will work. If the drive doesn't have a 50pin connector, you will need to buy and install a converter.

Several people have reported success using IDE->SCSI converters, and installing IDE drives in their Indys.
