Upgrading a Mac motherboard

[Lars Aruns]

I might have an occasion to purchase a second hand Mac motherboard for just a symbolic charge. The guy describes it as being a Apple Mac G3 Blue/White Motherboard, and gave me a model number of 820-0987-A. I tried my luck on Google, but it is much easier to find specs for whole Macs than for their parts.

I'm thinking about buying it and putting a G4 on it if it is possible. First of all, does it make sense? In any case, do you know of a site reporting this kind of technical specs, and possibly some kind of tutorial/HowTo?

I believe the G3 motherboard has a ZIF socket for the processor itself (if I'm wrong, the most likely alternative config would be processor-on-a-daughercard). Yes, you can upgrade it to a G4. Sonnet, XLR8, Newer Technologies, and PowerLogix all produce upgrade CPUs for the G3.

Won't do you a hell of a lot of good without the rest of the machine's boards and ports to wrap around it, of course :p

Absolutely! :) Well, the motherboard comes with a power supply, and I think I can grab a video card, keyboard and mouse on Ebay. If there is an IDE controller on board, fleshing out the machine shouldn't be a big problem. Hopefully...
