Noel's idea around the DLV-11 not passing the grant might have been an
issue, so not completely random! However, I've been guilty of plenty
of random testing before!
Well, not important. We're now beyond that point. The boards are working
well enough that we can address them...
I unfortunately don't have an extender card... I
just searched eBay
for a few things, but didn't see any. Do they have a part number or
some other description that I might look for?
I have no idea if they have any designation or part number. I bet they
do, but I don't remember seeing any on my extenders, and I'm not close
to them now, so I can't check.
Looking through ebay, I found one 2-slot extended here:

That will give you an idea what they look like. I've seen 2-, 4- and
6-slot versions. Obviously you can use several 2-slot ones if you need 4
or 6 slots extended.

Even better. Sorry for writing responses without
checking what else is in my
inbox. I've caught up now, though.
And you definitely look like you got a stuck bit in there.
All of the errors show expected and received data, and in all cases bit 13
is on while it shouldn't be.
Could be a bad bus driver, a bad connection, or something more funny. But
start with the obvious ones. Do you have any extender cards so that you can
access the card with the power on, and measure signals. Checking the source
of bit 13 on output and trace if the signal is always on somewhere would be
a good exercise.
Do someone remember if there are some register in the RLV11 that can be
written and read back getting the same data out again? That could also be
interested to test things with...

Thanks John, I think the insanity is my own! After changing those
switches I accidentally put the M8014 above the M8013. I've swapped
them and now get slightly different results:
One note, it now takes a while for it to start printing anything,
which I think might mean it's running some of the first test
successfully before getting to these. Earlier runs would start
printing errors immediately.

Bit 11 of the CSR seems to be stuck on. That's the "bad CRC" (or write
check error) bit ... definitely shouldn't be on after a bus init.
Maybe look at some other registers to see if that bit's on everywhere
(possibly bad bus xcvr if so), otherwise some other insanity?
