Does anyone remember where this was used? It's a hex 9 slot backplane that
I think is Q-bus.

The name certainly implies that ? device names with V for the 3rd letter were used for
Q-bus devices (like DLV, DHV, DMV).

The DDV11-B is described in the PDP-11 Microcomputer Interfaces
Handbook as "an optional LSI-11 bus expansion backplane for use when
additional logic space is required." It doesn't mention any examples
of where it is used.

I have a DDV11-DK, 4 slots. It came in an 11/34 from a University
setting that also had an IBV11 and a DEC Unibus-Qbus converter. I'm
guessing it was what they could get at the time when they ordered an
11/34 with GPIB.

it. One was Unibus, and on the 11/34 bus. The other was a 4-slot hex
height Qbus backplane. There was a DW11-B board set (DEC Unibus to Qbus
interface) with short ribbon cables betwen the boards linking the 2
backplanes. The Qbus backpalen contaiend the special interface cards for
the cmaera, etc. I guess they were only made as Qbus.

this is a 9 slot hex.
Leave it to me to come up with weird things....
Thanks Paul
