Can I stick a 180 MHz (60 x 3) processor card pulled from a Power Computing Pro 180 desktop into my Power Mac 8500? I don't know if the PPC's are clock-locked (fixed multiplier), but would it automatically adjust to something the 8500 could handle, like (50x3, 45x4)?

It won't work - your 8500 was designed to run to 50 MHz. bus speed at best. I had a Powercomputing 250 MHz card (5 x 50) that would hung until I changed its crystal from 50 MHz to 48.
Oh well.
Apparently the PCP180's L2 cache isn't working in my 8500. It's 512 KB and capable of running at 60 MHz. Logic says that if it can run at 60 MHz, it can run at 50 MHz just as well. With it in, I get the startup sound but no picture (through the video out).
