Tu10 pdp11

[william degnan]

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.
