From william degnan
I was looking to see if references to the tm11 were
"module/card" or
backplane interface.
I think pretty much all that earliest generation of UNIBUS interfaces were
stand-alone backplanes (i.e. 19" wide things that went in an H960 in a fixed
location, and were filled with the small Flip Chip modules); the RK11-C,
RP11-C, RF11, and TC11 all are.
I surprisingly found little commentary or threads
about the TU10 /
TM11, other than DEC docs. I guess these are not super common
Yeah, I think they were the first PDP-11 tape drives - not as rare as RF11's
now, but pretty rare.
