Hi Dave,
In my ignorance I incorrectly assumed the DHQ11 was a SCSI controller
because it has compatible centronics sockets. Thinking about the name
that was obviously wrong!
For the future:

I've not seen an octopus cable in a long time.
I was fairly sure it would be ok so plugged it in and managed to get
into the Emulex configuration menu very quickly. Next step, installing
NetBSD :)))
I have two Emulex UC07, one is spare and the
other is in my PDP-11. If I
install this into the VAX Q22 bus do you think it will explode or work?
The BA440 Qbus is 22 bits, so that should be fine shouldn't it? I've
never tried that combination, so I don't know for sure, but I think the
BA440 is QQCD (or whatever the designation is), no serpentine. Even if this did work it wouldn't be ideal
but I'm not sure of any
alternatives at the moment.
KDB50 + RA drive? An RA7x would (almost certainly) fit in one of disk bays.
You're supposed to use RF disks. I have an RF35 (or maybe two drives)
here but I don't know their status. I *think* they're SCSI with an
adapter board, and if so I could check the disk status at least.
A further alternative would be an HSDx0 + BA350 + StorageWorks disks in
caddies.
