I have for sale a 1GHz 7455 G4 for all 100MHz and 133MHz G4 Macs. This includes 350MHz Sawtooth through dual 1.0GHz Quicksilver. This is a 7455 which means you can use it to install any Apple OS that your G4 supports. I am asking $100 shipped through the USPS to the United States. International people are welcome but the shipping may be a little different.
I accept paypal or money orders.
Oh, this is not a 1GHz PowerLogix upgrade, I have read too many horror stories to even consider buying one.
