Uhh, the same way they get your current G3 to operate at 400 
MHz...different clock speeds for the system bus and the processor.

No, your system will not be as fast as a G4/500 running on a higher 
speed bus, but it will be faster than your current setup.

Yes the system bus will be a bottleneck; it is in pretty much all 
systems these days, absent poor memory and disk configuration, since 
processor speed far outstrips the fastest bus speed these days.

If I still have my 66mhz bus in my lombard, will I
truly get a "G4/500 machine" if I do the Powerlogix or
Newertech upgrades? Wouldn't the 66mhz bus act as a
bottleneck?
How do they get the computer to process at 500mhz?

This voids the warranty.
Many of the 400mhz Pismos are just out of the warranty window amyway.

Pismo CPU ugrade

2002-07-24 Thread T-Lo 

Is there a Pismo CPU G4 upgrade available? If so, from whom is it 
available?

I have a Pismo 400MHz G3 with 576 MB RAM running OS X. It is a great 
machine.

Would a G4 upgrade, if there is one, provide a significant performance 
kick?
