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.
