Apple Power Macintosh 7300 series - PC Compatibility Card - Manual (Page 117)

20 Route the second cable over the top of the PC Compatibility Card, behind the processor
card, around the back of the logic board, and through the hole in the computer’s chassis.
Be sure to route the cable between the processor card and the back panel (not
over the top of the processor card).
Keep the cable away from the heat sink and the center support post.
You’ll connect this cable to the CD-ROM drive in step 26.
IMPORTANT If you are installing the PC Serial and Parallel Card, you should
insert it now. See the PC Serial and Parallel Card manual for instructions.
Route the cable around the back
of the computer’s interior as shown. Feed the other end of the cable a few
inches into this hole in the computer chassis.
