O.K., I checked the DC cleanlyness with the scope and it is wonderfully
clean. But it's strange. When I first power it on just power the memory,
the lights on the key-switch console are all wild (like green and red all
at the same time.)
Again the DWMBA didn't work. And caused machine checks errors. Again
two of the XBIA cards caused the CPU to shut down the moment it was
going to test the VAXBI stuff. Can you tell from the transcript below
what might be wrong?
Whithout XBIA it seems to be working fine. Now I put in just one
of them without an XBIB counterpart:

?12 Machine check occurred during machine check processing.
PC = 2007C25F
SAVPSL = 041F1200
ISP = 201403F0
What the heck? Hit the reset button and:

ROM0 = V3.00 ROM1 = V3.00 EEPROM = 2.03/3.07 SN = AG94408846
This time it worked. No VAXBI stuff detected, sure, there is none.

Now I put the other XBIA in and two XBIBs to talk to. See what
happens this time

and boom, the CPU lights went out. What's going on here?

Now that I see those machine check issues, I think I've seen
those before. It might be that these problems had been waiting
for the last year to come up. I guess I should be replacing
everything with the spare set of guts that I have boxed up.
This isn't right, and I don't know what else to do.
cheers,
