Re: Dead SS20 NetBSD machine

Is it more likely to be the CPU module (it's got a HyperSPARC 125 MHz CPU) or a dead motherboard?

In a previous incarnation, my primary E-mail host was an SS20 with 150 MHz HyperSPARC CPU; one day it died, and hoping that it was merely the CPU, I swapped in a spare HyperSPARC CPU that I had around, and, lucky me, the system booted again and ran acceptably for some years until I replaced it with a Sun Fire V120.

This, of course, is anecdotal, not definitive.

I don't think you have much to lose by trying a different Mbus CPU module in your SS20. However, it might be a good idea to check that all the outputs of the power supply are up to snuff (you're actually getting +5vdc and +12vdc in the right places), before swapping in new hardware.
