I had a 9150 board in my 950 that died when the voltage regulators for the cpu asploded.
It's fairly easy to steal a replacement from a 7500/100 CPU card. Since there is no CPU card slower than the 601/100 card those cards are usually cheap to free if you can still find any of them laying around.
However, if the regulator took anything else with it when it went, then the fix is not so simple.
I can't remember the exact part number but it's a linear technology part.
