3.
Accelerator Cards:
››
Since the processor in PowerMac
G5s, PowerMac G4s, PowerMac G3s, PowerBook G3s, and
iMac G3s (with TrayLoading CD) is removable, third
party manufacturers have developed Accelerator Cards
(processor
upgrades) for many of
these computers.
››
Accelerator Cards provide older models
with a serious performance boost and are often an
effective and economical alternative to simply replacing
a defective processor with just another Apple part.
››
Naturally, the processor doesn't need
to be defective to merit replacement. Accelerator
Cards are designed to give your older Mac a new lease
on life!

The links in the OPTIONS pulldown menu to available
accelerator cards for these computers are listed by
