Calling all experts...

Has anyone of you ever done this or have any inside info on how to do it?

What I would like to do to the above mentioned machines is:

1. Install 40 MHz oscillator to make all subsystems and RAM run @ 40 MHz.

2. Downclock PPC601 processor back to 80 MHz since I don't want to overcook it. I will be running NewerTech G3 PDS, so all I need is 40 MHz bus.

Cheers,

OJ
