I think the DEQNA board is dead, even before I
started moving things
Not unlikely.
around on the QBus. (Yes, there'll be Yet Another
"Broke My QBus" Post)
I haven't ever been able to get it even to light up the AUI terminator.
Ok, Check fuses, there are two if memory serves, one on patch pannel
cable to the board (a visible fuse holder!), the other is on the board.
Even a dead board will power the AUI though that's about all.
FYI: there is a lineup for what order the DEQNA(DELQA) and TK50
controllers must go on the bus relative to the other IO cards.
I have NetBSD running on the VS4000/60 and a TK50Z-GA
that works. I
can tar to /dev/rst0 and then retrieve the archive all day long. When
my boot tape wouldn't boot on the MV, I wondered if its TK50 is toast,
so I've been trying to boot the 4000 to test the tape.
All the sources say to:
The Drive in the -GA will be the same as the one in the MV so you
can swap it in. Do make sure the TK50 controller has the dip switches
set right as some were easily bumped on install.
Trying it on the MVII gets essentially the same
results. No
meaningful error message, just the HALT instruction.
MVII has a very limited console boot and diagnostic compared to later
models so it's not very talkative.

Already checked the fuse on the patch panel, but I missed the one on
the board. I'll look at that next. I also have an orphan cable &
bulkhead set, that I was gonna try.

I'm assuming that Hamster's QBus tutorial is correct? I'm going by
that;
slot 1: CPU
slot 2: RAM
Slot 3: RAM
Slot 4: DEQNA top, baffle (black board, no traces at all) bottom
Slot 5: TQK50 top, RQDX3 bottom.

OK. I did find the TQK50 docs too. But so far, I can't even boot
from tape on the VS4000, where it was made. I think
either the boot.fs
doesn't support the VAXstation, or I'm missing something
critical.

I had noticed that, yes... :)
Thanks.

Might you have a broken interrupt chain here? Is slot 4 a Q22/Q22 slot
or a Q22/CD slot? That air baffle won't grant the interrupt chain very
well, and unless it's in a CD slot, the only device that can generate
an interrupt is the DEQNA.
It's possible to load a bootstrap and hang when the real software kicks
in. I am debugging an H-11 that has an H-27 floppy interface that won't
work in the chain but will let me load the bootstrap if I put it behind
everything else with a gap (it seems to not let go of some Qbus signal
and when it's properly installed, I never get an ODT prompt).
I don't know the particulars of the box you have, but BA23s have 3 CD
slots, not 4.

It's _supposed_ to be a CD slot. It's aBA123 box, The docs say 4
Q22/CD and 8 Q22/Q22, and if you look very carefully, there's a line
silkscreened between slots 4 & 5 on the cage. Putting the grant card
instead of the baffle breaks everything....

Well there you go... I wasn't sure that you had a BA123 (I had _thought_
so, but I wasn't sure). Nice of them to put a little line in there.
I'm sure that a grant card could freak things out. Some of the quad
cards I have (MSV11P?) let you jumper or unjumper the left side, to
let you stick them in either kind of slot.

Bingo!!!
I have that stripped BA123 in the garage that has a DEQNA
cable/bulkhead still in it. After reading Allison's statement, I read
the DEQNA docs more carefully, and the LED's show correct activity on
the board itself. So, after feeding the cats and bathing in sunburn
lotion, I swapped out the cab kit, and have netbooted the NetBSD kernel.
I think I'm going to netboot NBSD on NFS filesystems, use it to label
the local disks and see if I can get Quasijarus0a installed.
I haven't yet tried the suggested boot tape images, but I probably
will, just to see what I was screwing up.
Thanks to everyone for the help.
