I feel your pain brother....
On one of my CSPPC board I have the same problem. 060, ram and SCSI works as it should, but whenever I try to run some PPC software the computer crashes

A friend of mine got a BPPC where the PPC cpu didn't work as it should; it also crashes the computer I think. He downclocked his PPC cpu, and then the PPC cpu came back to life. I'm going to ty it out at least; hopefully I will get my PPC working again. If not I will manage with a board acting as a CS 68060 board.
