readily apparent: the replacement is currently noticeably quieter than

the original even though it is moving more air per minute.

Make sure the System Saver is unplugged before opening the case.

Opening the System Saver case involves removing eight screws. You must

remove the foam weatherstriping along the periphery of the case to expose

the screws. Once the weatherstripping is removed, you should be able to

see the screw access holes. They are arranged as shown in the following

diagram (bottom view of the System Saver):

Once inside, the fan can be removed by unplugging the power cord that

connects it to the circuit board. A grounding wire that is attached by

a screw must also be removed. The fan itself is held to the case by

two screws. Once you remove the SU2C7, you can replace it with the

SU2B1. Now mount everything back together again with the screws. Apply

new foam weatherstripping to the periphery of the bottom of the system

saver.

The refurbished System Saver is now better than a factory new model!

Notice the difference in sound: a quiet hum rather than a load rumble.

If you have a lot of cards, you will notice that the inside of the IIGS

is a lot cooler too. An upgraded System Saver is a great way to

counteract accelerator instability caused by heat.
