Hey, I have a G3 CPU card that works in PCI Power Macs and clones. More details available at the most excellent EveryMac.com:

I'm in Ottawa (in an igloo, in Canada) and I'll pack this thing up safely in anti-static bubble wrap and ship it out. First person who agrees to send me the cost of shipping over PayPal gets it. Thanks,
Sayyad Glassford
