Illustrated Tour of the Installation Process

Steps to upgrade the Performas 5xx to the MicroMac PowerPC 5200

Tools You Need:

Philips screw driver

5 mm or 3/16" socket drive


Step 1:

Verify the proper operation of your Performa 5xx

verify the current system software that it is compatible with the MicroMac PowerPC 5200 upgrade.
The MicroMac PowerPC 5200 requires System version 7.5.3 or higher.
If you have installed this System on your current Performa using the "easy install" we strongly recommend running the installer again with selecting "customized" and "for any Mac".

Step 2:

Prepare your computer

Shut down your Mac properly.
Unplug the power cord and remove all cables from the back ports.

Step 3:

Open your Mac

Remove the two screws on each side of the back panel.
There are 2 tabs on the back panel.
Push these tabs down while pulling.
Now the logic board is exposed.

Step 4:

Remove the logic board

Pull the logic board out of the chassis.

Step 5:

Preparing new logic board

verify the connection of the battery on the new logic board.

Step 6:

Preparing for optional Ext. IDE connection

connect the IDE cables if you purchased the ext IDE option.
The power cable goes into J3, the IDE connector into J2 (pin 1 is towards the left).
Remove the cover plate for the External IDE opening on the extension chassis with the philips screw driver.
Install the External IDE connector by mounting it with the two Hex-nuts.
Make sure both the IDE cable and the power cable are connected from the logic board to the IDE adapter-board.

Step 7:

Installing the 5200 logic board

Have the Performa face down and slide the new logic board into the chassis. Watch for the two rail slides which guide the logic board as well the metal standoffs on the bottom of the new logic board so they do not get caught while sliding it in the chassis.
CAUTION: the new logic board is longer then the old one and will not slide in all the way. It is about 3" longer then the old logic board. However you'll feel a little resistance first when the edge-connector hits the mating connector, then you have to push it further for about 3/4". Do not use accessive force.

Step 7a:

Test the new logic board

Before you continue, you may connect the main power cord and the keyboard and "fire up" the new logic board.
In some cases it is necessary to reset the new logic board by pressing the reset push-button. The reset push button is located on the logic board (see circle)

Step 8:

Install the extension chassis

When installing the extension chassis there are 3 points of support. The two screws on the top and the tap on the bottom side center. Make sure the opening snaps into the center tap of the main chassis. You need to press onto the metal tap in order to clear the plastic tap.

Step 9:

Secure the extension chassis

Use the provided screws (M3x8) to secure the extension chassis.

Step 10:

Connect the external IDE drive

If you have purchased the external IDE option, you may connect it now or after you have verified the proper operation of the new system.

Step 11:

Enjoy your increased speed
