Somehow I was afraid you were going to ask that :^) I have no idea. Thats
what I like about genuine DEC boards, they seem to be easy to identify
compared to the 3rd party boards.

There is a little barcode with AV9422 under it, the board itself says
Assy. QU0110402 Rev. G and has a date of 1985. There are two connectors
for the smaller cable, I've got one going to each of the drives. The cable
that goes to the switch is such that you can plug in two switches, I've
only got the Emulex switch plugged into it.

The big cable is a bit off, it's got connectors for three drives, two don't
have a twist, one does. The cable is such that I can use both without, or
one with, one without. Neither combo seems to work. I've got DUB1:
attached to one of them without the twist. The twist is 7 wires around 10
- 16 (can't tell the exact).

See above.

> What sort of drive?

DUB1: is an RD54
the drive I'm trying to use for DUB2: is a RD53 (it was working a 2 or 3
weeks ago)

On Card:

SW1: 1 2 3 4
     0 1 0 0

SW2: 1 2 3 4 5 6 7 8
     0 0 0 1 0 1 0 0

On Switch Card:

SW1: 1 2 3 4 5 6 7 8
     1 0 0 1 0 0 0 1

Um, what termination?

>B. Run the diagnostics to format and verify the drive.

The drive should actually be good to go, I'd loaded a copy of VMS out to it
for another of my systems, but I need the extra space on the MV2, so I
wanted to attache it there. I thought this would be easier than figuring
out how to get the ESDI controller and drives working :^(

>III.Configure your OS to use the drive.

Hmm. I should be able to simply mount it I would think. Is there
something else I need to do to access it? I'm not trying to get it
permantly accessable on mount.

Hope this is better, but I'm doubting it. I wish I new what kind of
controller it was.
