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.
