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. JRJ
