The Power Macintosh 7100 was one of the first PowerPC based Macintosh systems released along with the Power Macintosh 6100 and Power Macintosh 8100. The 7100 was released in March 1994.

The 7100 was replaced by the Power Macintosh 7200 and Power Macintosh 7500 models.

General Information

Also introduced in March 1994, the Power Macintosh 7100 was a faster and more expandable Power Macintosh 6100. It came in a slightly restyled IIvx case, and was "speed bumped" to 80MHz in January 1995. It was originally priced at $2,900.

Codenames: Carl Sagan, BHA, LAW. Originally shipped with the PowerPC specific version of system software 7.1.2 with later models featuring System 7.5 and PowerPC enabler v1.1.1.

CPU

The Power Macintosh 7100 is based on the PowerPC 601 processor with available speeds of 66MHz and 80MHz.

Memory

8 MB RAM soldered on logic board, expandable to 136 MB via 4 SIMM sockets on logic board (using pairs of same size, 80 ns or faster, 72-pin noncomposite SIMMs); 16 MB configuration has two 4 MB SIMMs installed.

Note: SIMMs must be installed in pairs of the same size and speed. Install noncomposite SIMMS only.

Expansion

The PowerMac 7100 is a NuBus based Macintosh with three expansion slots. There is also Processor Direct Slot (PDS) expansion, typically used for a standard video card or AV card for the AV model.

Cache

  • 7100/66: 32K of on-chip cache; optional 256K level 2 cache available
  • 7100/80: 32K of on-chip cache; 256K level 2 cache standard

Notes

  • The PowerPC 601 processor is very fragile and putting too much weight on the heatsink may actually crack the CPU.
  • The 7100 model in particular is said to have poor heatsink compound and the system will likely overheat unless the original compound has been cleaned and replaced.

Troubleshooting/Repair

Capacitor replacement (logic board)

The SMD capacitors on the logic board will most likely have already started leaking electrolyte out the bottom, and failing to replace them in a timely manner will result in further leakage with possible damage to nearby components. See below list of capacitors to replace:

  • 25 x 47uf 16V
  • 1 x 100uf 6V
