G3 iMac cpu swap to B&W G3 Powermac

I'mtrying to figure out what type of cpu the iMac has since The Power Mac is needed for more demanding tasks, just seeing if I can swap the cpus, it would help, and since the Imac isn't here for me to open at the moment I can't fiddle with it myself.
Wikipedia was useless as well, also other apple enthusiast sites.

All the mac info available is below:

Power Mac is a Blue and White G3 350Mhz with available room for a v-card upgrade later.

iMac is a first gen slot load 500Mhz with an 8MB(as opposed to the newer 16) rage 128 so I'm sure it's not the latest G3 imac...

Any help is good help, thanks.

If I remember things correctly, the G3 iMacs all have their CPUs soldered to the logic board. Maybe with the exception of the tray loading iMacs, but I don't think you can just pull the iMac CPU and put it in the B&W. You would probably be able to get a CPU for the B&W for a *very* reasonable price on eBay or your local Mac store since the G3s are rather long in the tooth.

Check <a href="http://www.lowendmac.com">LowEndMac.com</a>.

<a href="http://lowendmac.com/imacs/index.shtml">iMacs</a> (scroll down for the G3s).

iMac CPUs are permently attached to the motheboard - no swapping there. But instead of getting a G3 ZIF CPU for the Blue/White, find yourself a G4. Much better and faster than the G3 and a quick look on eBay found a couple starting at $70US for a G4/450.

Or even better sell the iMac 500 (still a useful machine) for $200-300 and use that money for get a G4/500 or better ZIF from Sonnet.
the crap is piled high ... now trying to keep up

We've got lots of G4 Zifs around but it depends on the motherboard of the B&W if it's practical.
You'd be better to trade the iMac for a G4 tower and leave the B&W alone.

In Australia and the web site is out of date.
Lots of good deals on Retinas, previous high end MacPros and current MacPro 6 core bundles in stock. [email protected]

OWC (OtherWorld Computing) has accelerated CPUs for your B&W, up to 1.1Ghz for a G3. I have been running mine with a 900Mhz upgrade for about 3 years.

You can get G4 upgrade CPUs (must be a special type, not just any old G4) - but sadly, the B&W towers cannot handle a G4 faster than 600Mhz unless they slow down the system bus from 100Mhz to 66Mhz, which cancels the advantage.

I'm just planning on running this G3 temporarily for basic internet uses and whatnot, but it may be used for a good year by my mom afterwards before I turn it into a case project(simple ATX conversion) But until I get it into my possesion(sitting at my dad's place) I can't tell you which G3 it is, but I do know to get OSX running even alright, I need a cpu, ram, and a possible video card, but I've heard some trouble with the HD so I might wanna look into throwing an Ultra ATA card from work in there, any suggestions welcome, browsing those links as soon as I finish typing(meanwhile hoping I see two drives bays with two compartsments in each as opposed to the dreaded one with three, a distinct difference between the good and bad, or rev 1 and 2, B&W according to wiki).
Thanks for the help.
