Power Macintosh 7500 or 7600 Series Computers
The Power Macintosh Processor Upgrade Card gives your Macintosh 7500 or
7600 computer additional processing power. You can install the upgrade card
in the processor card slot in your computer.
This chapter explains how to remove the processor card currently inside your
computer and replace it with the processor upgrade card. Installing the
processor card is technically challenging. If you prefer, you can ask an Appleauthorized dealer or service provider to install it for a fee. If you attempt to
install the card yourself but experience difficulties, it is recommended that
you have an Apple-authorized service provider complete the process. Apple
does not warranty damage caused by improper removal or installation of
processor cards.

Installing a processor card
While pressing the release buttons, pull the top cover forward
approximately two inches to release it from the chassis.
Locate the two release buttons under the front panel ledge with your fingertips.
1 Turn off the computer.
For now, leave the computer plugged in to ground it and protect its
components from static electricity damage.
2Press the two release buttons under the front panel and slide the cover toward you
approximately two inches.

Always do this before you touch any parts, or install any components, inside
the computer.
5Unplug the power cord from the back of the computer.
Because you discharged static electricity from your body in step 4, you can
unplug the power cord and handle the processor cards. Be sure to avoid
actions that might create static (such as shuffling your feet on the carpet).

WARNING
The processor card can be damaged by static electricity. To
avoid damaging the card, hold it only by the edges—do not touch the
gold contacts or the heat sink. While handling the card, avoid actions
that might create static. For example, do not walk or shuffle your feet on
the carpet.

Follow the instructions for installing or reinstalling system software in the
manual that came with your computer. Start up your computer with the CD
that came with your new card and follow the steps for a “normal” installation.
WARNING
Never turn on your computer unless all of its internal and
external parts are in place. Operating the computer when it is open or
missing parts can be dangerous, and can damage your computer.
What to do with the used processor card
Put the used card into an antistatic bag. (You may want to use the one that
contained the new card you just installed.)
It is possible that the processor card you removed can be used as an upgrade
card for another Power Macintosh. For information about the cards you can
use in specific computers, be sure to see the Appendix, “Swapping Processor

Swapping Processor Upgrade Cards
This appendix provides important information about different processor

Macintosh computers you may have.
What to do with a used processor card
If you removed a 120 megahertz (MHz) processor card from your Power
Macintosh 7600, 8500, or 9500 series computer, you can use it to upgrade the
processor in a Power Macintosh 7500/100 model. Follow the instructions in
Chapter 1 of this manual.
If you removed a 132 MHz or 150 MHz processor card from your Power
Macintosh, you may be able to use it to upgrade another Power Macintosh
model. Follow the steps on the next page to determine whether you can use
the card in another computer.

Communications regulation information
FCC declaration of conformity
This device complies with part 15 of the FCC rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation. See
instructions if interference to radio or television reception is suspected.
Radio and television interference
The equipment described in this manual generates, uses, and can radiate radio-frequency
energy. If it is not installed and used properly—that is, in strict accordance with Apple’s
instructions—it may cause interference with radio and television reception.
This equipment has been tested and found to comply with the limits for a Class B digital device
in accordance with the specifications in Part 15 of FCC rules. These specifications are designed
to provide reasonable protection against such interference in a residential installation. However,
there is no guarantee that interference will not occur in a particular installation.
You can determine whether your computer system is causing interference by turning it off. If
the interference stops, it was probably caused by the computer or one of the peripheral devices.
If your computer system does cause interference to radio or television reception, try to correct
the interference by using one or more of the following measures:
m Turn the television or radio antenna until the interference stops.
m Move the computer to one side or the other of the television or radio.
m Move the computer farther away from the television or radio.
m Plug the computer into an outlet that is on a different circuit from the television or radio.
(That is, make certain the computer and the television or radio are on circuits controlled by
different circuit breakers or fuses.)
If necessary, consult an Apple-authorized service provider or Apple. See the service and support
information that came with your Apple product. Or, consult an experienced radio/television
technician for additional suggestions.
IMPORTANT
could void the FCC Certification and negate your authority to operate the product.
This product was tested for FCC compliance under conditions that included the use of Apple
peripheral devices and Apple shielded cables and connectors between system components. It is
important that you use Apple peripheral devices and shielded cables and connectors between
system components to reduce the possibility of causing interference to radios, television sets,
and other electronic devices. You can obtain Apple peripheral devices and the proper shielded
cables and connectors through an Apple-authorized dealer. For non-Apple peripheral devices,
contact the manufacturer or dealer for assistance.
