I/O Cards
Power Macintosh G3 computers require an I/O card that moves
audio and/or video from the main logic board. These cards are
placed in the PERCH connector on the main logic board. If the card
is not seated correctly, different symptoms appear. Look in the
Symptom Charts for details on troubleshooting these cards.
Note:
the Power Macintosh G3 computers will boot up without the
I/O card installed, but they will not operate properly.
