Processor Module
The Power Macintosh G3 logic board comes with a removable pro-
cessor module. You can replace this module when the logic board
or processor module fails. The processor module sits in a ZIF
socket for easy removal. Processor modules can be ordered from
Service, and each is shipped with the appropriate jumper config-
uration block to place in location J16. The processor should
rarely fail. Replace it only as a last resort.
When replacing the processor module, you must change the pro-
cessor jumper block and warranty sticker to be compatible with
the processor module you are installing. Failure to install the
jumper block properly will result in a unit that does not boot up.
Refer to “Processor Module” in Take-Apart for installation
instructions.
