I have available a number of what looks like industrial PDP-11 stuff.
These board do have a grey handle and are marked 'BH-xxx' instead
of 'Mxxxx'.
Several boards, single, dual, quad & hex ones. And also a backplane.
If interested, let me know off list.

New subject: Pics of the industrial PDP stuff + unknown ones
I have placed some pictures of the Industrial PDP stuff on my
web page, see the url below. I also found a few boards probably
related to the industrial stuff, which are the M8094, the M8096
and the M8098. All are ICR-11 boards.
I also have placed a picture of an ACT board I cannot identify.
Anybody able to tell me what it is?

Act made controller and peripheral test equipment if it is the same ACT
that was in Santa Ana, Ca. I only knew much about them after they
crashed and burned and Advanced Computer Products bought a large amount
of their estate at auction for liquidation. I figured that boards like
this were shim boards they made so they could verify 2 high controllers
under power in circuit, but it may have been for other purposes they had
to stack boards. I only saw what you have, not the boards plugged into
systems, as what ACP had was all disassembled boards like you have in
the photos.

Just based on the shape and the presence of numerous DS8641s top and
bottom, I'd say that looks like a Qniverter or Univerter-type bus
adapter board. I'd check the locations of power/ground and groupings
of signals to the DS8641s by the upper edge socket, but you probably
plug this board into a Qbus box and run a BC11 cable to a DD11CK or
DD11DK to use Unibus peripherals in your Qbus machine. It's possible
it's some other specific configuration (since DEC _did_ make a
hex-height Qbus backplane for mounting an IBV11 in a BA11 cab to use
it with a Unibus processor), but those sorts of bus adapters tend to
use a different cabling arrangement than a BC11.
I am unfamiliar with the ACT name, but that's my opinion based on the
board shape and chips present.
