I think a lot of the unreliable experiences with tk50 come from the actual
tape cartidges and the BSD TMSCP driver.  With new tk50 cartidges used on
Ultrix 2.0+ systems, they seem to work without hassles.

The VS410 CPU (microVAX 2000 and the VAXstation 2000) interfaces to its
TK50 (actually a TZK50) through a SCSI interface.  The TZK50 or TK50 are
are using SCSI already.  The drive is hooked up via a 50 pin connector.  The
5380 tape controller chip which implements the slave's end of TMSCP is
right on the main CPU board.  

If you want more exact details, order the following tech. manual from
your local DEC rep,  EK-VTTAA-TM-001 (aka. VAXstation 2000 and MicroVAX-2000
Technical Manual).
