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
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
