Thanks. There are 2 backplanes at 90 degrees of each other installed in the
cabinet. 2 separate power supplies. I still need to inventory the cards
and look up what they are configured to do. I have cables. Just getting
started.

Ok. I checked my tu10, it has the backplane, it
is a master. I see
where
it connects using the backplane cable to the
pdp11. I never worked with
a
TU10 before and I was looking to see if
references to the tm11 were
"module/card" or backplane interface. I surprisingly found little
commentary or threads about the TU10 / TM11, other than DEC docs. I
guess
these are not super common or people who have
them have not often reached
out to the classic cmp community, that I could find in a search.

Just to be clear, a TU10, even a master, does NOT connect directly to a
PDP-11. Instead, a cable of the same general ilk as a BC11 UNIBUS Cable
(but I have not verified it is in fact the same kind of cable) connects
the drive to the TM11 controller.
The TM11 connects to the PDP-11 UNIBUS.
The TU10 master drive backplane has some "G" cards in it. The TM11,
mounted separately, does NOT have any "G" cards in it.
