Hi
My main system a VAX 4000 Model 500 with a KA680 CPU has just
started halting at test 51 on power up.
Does any body know where I can lay my hands on a spare KA680?

A month ago this one went by cheap enough on eBay at $50 that I was
tempted to try to grab it just to have another spare in case I or
someone else needed one some day. Too bad I passed on it. Sometimes
you can find good deals on them on eBay, but of course not when you
really need one.

It was ever thus "When you want one you cant find one and when you

Oh well switching to backup (4000-300)

The system maintenance manual claims that ?51 means "NOROM No valid ROM
image found", which seems a bit odd.
But that's a VMB message, so unless it was trying to boot then perhaps
I'm looking in the wrong place ...

Hi
Thanks its now OK - The latches that hold the CPU board in are
not a good design and the board was making intermittent contact.
