Summary: TU81 and TMSCP are what the TS11 uses, or so I understand. Both BSD and SYSV hav drivers for TS11 - problem solved.

When given the commission to write a TU80 driver for SYSV, I too
approached DEC about it, and was given all sorts or rubbish until
finally I spoke to someone who knew a bit about the subject, who taold
me that the TU80 and TS11 are identical except for some obscure error
returns and possibly error recovery techniques. I then compared TU80
and TS11 manuals and couldn't find any practical difference. Needless
to say, my TU80 driver worked first time...

The TU81 is a TU80 with higher density available: no worries, it's
such a simple change to make it select 6250 for the right minor
number.
