Hey folks, anyone familiar with the high score/diag kit from Braze? Specifically the diag part of it..

I wanted to see if it would help me with a repair, but am not sure how to interpret what I'm seeing.

First it checks ram (some are OK some are not), then it checks the NMI.. at which point it reboots.

So does that mean the watchdog timer kicked in (meaning didn't kick in) and the CPU rebooted? Or does that mean it didn't get an OK from the NMI and the diag kit rebooted itself?

It means you have some bad rams or the cpu can't access them. What are the error code showing?
 
bad ram

Yep, that's what it's showing - some bad 2114s. I'll replace those. Is ram the only thing that triggers NMIs on that board? (I seem to recall that this is the case, in which case it adds up)

Thanks for the quick reply!
