I never really looking in to this, but out of curiosity does anyone know what CPU options are available for ye old blue & white G3? 
If you want just a G4, you could install a CPU from the Yikes! PowerMac G4. After installing this, you should be able to drop one in and use it.
I suspect that is what i have in it atm, I've not used my B&W for some time. I actually prefer my PM8500, as I found the B&W a bit slow and sluggish. I did install an PCI ATA card, due to the 10gb limit on the onboard motherboard.
Was it 8gb? I just recall swapping out the old 10gb drive and it corrupting my 20gb drive.
Rev. A B&W G3s are weird computers. I have a couple kicking around, but I tend to use the Rev. Bs when I want to do special projects.
@LightBulbFun has a real dislike of Rev. As. A while back, two popped up on Ebay UK that I really wanted-one had a 1ghz PowerLogix G3, and the other a Voodoo 5 5500 GPU(both rare upgrades). Since it would have cost a fortune to ship both across the pond, and I'd have ended up with a pile of broken plastic when they got here, I asked him if I could have them shipped to him and then have him relay JUST the parts I wanted over here for me to assemble into one of my B&Ws. He was happy to do it, especially since it meant him getting to play with two pieces of rare hardware for a few days, and also got two B&Ws out of the deal. The only problem was that both were Rev. As, and I got to listen to him complain about me dumping two more Rev. A computers on him(I should mention that he and I are good friends, and his "complaining" was all in good fun-plus he was doing me a huge favor).
In any case, there's not to my knowledge any kind of 8gb restriction on any B&W. I don't want to speak ill of other fora, but 68kmla is not exactly my favorite place to turn for information on PPC stuff, especially NWR systems. It's hard to have productive discussions when one of the administrators is quite vocal about his dislike of those particular systems both from when they were current and any attempt at their continued use.
I guess that's probably going to be the best way of finding an upgrade for my system. Occasionally i swap around my 8500 for my B&W. Having read more online, I'm beginning to think the HD corruption cropped up when I added the new HD as a 2nd drive. Which apparently the Rev A's don't like.
As I said I've slept since I had all these issues and forgotten some of the details. I know buying the PCI ATA card really sped up the system. Still my G3 500 Pismo wipes the floor with it.
Just reflecting on the conversation thus far and a comment made about another vintage mac forum I visit. Since joining here, I have to say the experience has been great, everyone seems more animated to interact and discuss![]()
