[Info-vax] DS10 hardware troubleshooting - ref doc with machine check codes?

[Rod Regier]

I've looked but I've never found an online copy of a DS10 service manual :-(
I have never seen it referred to by other sources either.

Processor is soldered to main board of DS10 so no practical replacement there.

I have several other DS10 spare systems but just confirming I've exercised due diligence before scrapping this DS10 main board.  I operate as repair depot for my inhouse and external customer installed base.

Might be a PS problem even though >>>SHO POWER is happy.
That's probably about my last card to play.
