=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.

===Memory===
 
===Memory===
8MB onboard RAM. The system is expandable to a total 136MB.
+
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===
 
===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.

=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
