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.

Reading docs on DEC TU10 for pdp 11 one makes a

Not sure because I found little about baud, etc.
No.
I did not see any definitive controller card for
UNIBUS pdp 11. Maybe I
am
missing something..can anyone share experiences?
A TU10 master drive contains electronics[*] which allows it to be
interfaced to a PDP-11 TM11 tape control. Said electronics is probably
what's known as a formatter, though I haven't studied the TU10 in
detail so I'm not 100% certain.
A master TU10 can be used with up to seven TU10, TU20, TU30, or TU40
slave transports.
The TM11 controller has its own backplane, and may be mounted in the
TU10 master drive. It connects to PDP-11 using the usual BC11-A Unibus
cables.
