The TU81 (and the TA81) is what DEC calls a `TMSCP' tape.  TMSCP
is supposedly closely related to that well-guarded, secret protocol
called MSCP.  (The protocol is quite obviously secret, for only
DEC's competitors can buy DEC's documentation on it.  Or at least,
their competitors *did* buy it, and now DEC is not selling it to
anyone.  Does that make sense?)

Fortunately, at least one person at DEC seems to have retained a
shred of sanity where this is concerned.  The 4.3BSD distribution
contains a TMSCP driver supplied by DEC.  As Berkeley has no TMSCP
devices, this is perforce untested; but it is by far better than
nothing.  The driver has a large DEC copyright notice at the top,
and as I intend to distribute an MSCP driver that has hooks for
the inclusion of a TMSCP driver as well, I have looked no further
at it.  (No doubt this will become painfully evident to anyone who
attempts to merge their driver with my generic MSCP code.)
