Shared Logic Board
The Power Macintosh G3 Desktop, G3 Minitower, and
Macintosh Server G3 computers use the same logic board,
but there are jumper settings that differ between them (see
“Jumper Location J28” and “Jumper Location J16” in the
Troubleshooting chapter).
Processor Module Vs. Card
Whereas previous Power Macintosh computers featured a
user-installable processor card, this logic board uses a
processor module that must not be removed by the customer
(see “Processor Module” in the Take-Apart chapter).
