Calling for Mac CPU Experts! This is up for auction on ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5775714443&rd=1&sspagename=STRK:MEWA:IT&rd=1 I have a Sawtooth 400, and I'd like to know whether this will work in it. If it will, I'll bid on it; if not, I won't. There are several QuickSilver CPUs up for auction. I've heard they can be made to work with some hardware kludges, but I'm too old for that kind of project.
