Anything from another beige G3 will work. Processor, drives, ram from a
B&W will. But if there is a B&W carcass, it is best to upgrade that
with parts from your beige.
This being the case, with neither of us having seen a Sonnet before (at
least I've HEARD OF them from this list) -- in the event that one of
these dissected Macs has one, how would someone recognize it?
They would probably say Sonnet, or NewerTech or some other name on the
zif card. Easiest way is to fire up the mac before parting it out and
seeing what system profiler says about the processor

Sounds like conflicting information here.....maybe I should err on the
side of caution and tell my boyfriend that the processor has to come
from
a Beige, huh? However.....since Bruce is such a guru here, :-) Bruce,
what's the difference between the bus speed and CPU multiplier of the
Beige and the B&W? And, by "it will run at a different speed [in the
Beige] than in the B&W," would that be slower or faster? This would be
for installation only, no overclocking.
Bus speed on the beiges is 66MHz, B&W is 100. I am using a 350 from a
B&W in a beige at 400 with no problems.
In a beige, the processor speed is set by the jumpers that Bruce's link
describes. So that no matter what the processor says (exclusive of
sonnet and some other upgrades) it will run at whatever the jumpers are
set to. If you set the speed too high (533 for a processor rated for
266) it will either not run at all, or will overheat of start randomly
freezing the system

Bruce, O Guru, can you answer this one? I get the feeling that the
majority of the discarded Macs my boyfriend is dissecting more likely
have "stock equipment" inside them.
I have the pull from a beige that has a barcode on it from Apple with
the following text on it:
XPC750FIP266CF
XPC750- the manufacturers name for this particular G3
266- the rated speed
FIP and CF ??
Thank you. No overclocking is in the works; I plan to use the processor
"as is." We just wanted to know if a "regular" processor (i.e., not
overclocked) that's just faster than the 266 MHz in there now would
heat
things up too much.
No overclocking means no fan, unless you stuff the case full of 10K rpm
SCA drives (High speed, high heat server grade SCSI drives).
Right, OK. I originally had 9.1 on this system (and have an install CD
for it). I kicked it up to 9.2.2 via the free Apple updates (went to
9.2.1 first, then 9.2.2), which I still have, both on my hard drive,
and
backed up to a CD. So all I need to do here is "reinstall" 9.2.2 once
the
USB card is installed and then my Beige will recognize it?
If the card is not recognized, you can just download the usb 1.4.1
driver from Apple and install it.
HTH,
