Was the genuine IB11 a normal Unibus card? I've never seen one, I have
several IBV11 cards in MINC machines. I pulled the processor and RAM out
of one of the MINCs and hung it off a Unibus machine using (not
suprisingly) a DW11-B. I can confirm it works fine.
I once worked on something called a 'Gamma 11', which was a medical
imaging control system. It consisted, IRIC, of a PDP11/34 CPU with a VS60
board set in the CPU cabinet. That was linked by a Unibus cable to a
5.25" expansion box containing 2 4-slot backplanes. One was the normal
Unibus, and contains an RL11 and the Unibus half of a DW11-B. The other
was Qbus, it cotnained the other half of th DW11-B and some special
interface cards to the imaging camera, etc.
Alas I never got to investigate the 'interesting bits. I just had to fix
a simple fault on the RL11.

I see no reason why it wouldn't work. Certainly the DW11-B supports NPR
transfers -- I've run Unibus 11's with RL drives hung off an RLV11 (with a
DW11-B linkling them).
