OK, I'm soliciting diagnostic help from those more accustomed to Macs
A month or two back we obtained a Power Mac 7600 as rescue from another
lister. A little work got everything working and up to date, some

original PPC604e/180 back into it in place of the Sonnet G3 card, with
So: Any speculations on what's dead? Blown video? Dead motherboard?
