(Actually it was 1600 BPI only -- I *wish* it could do 800!)

Just Unibus, the TS11 had nothing to do with Massbus.

>TU45: 1600 bpi, Massbus. Maybe Unibus, don't know.

The TU45 is another TM03-based Massbus drive just like the TE16 and TU77,
actually AFAIK the only way for software to tell the difference is by speed
and the value in the MTDT register.  So it's a generic Massbus drive,
18-bit-capable with the right bit fiddler board, you can use it on Unibus
with an RH11 but it works with the RHxx(x) on any other machine too.  The
TU45 drive mechanism has a reputation for being junk, so it figures that
I'm stuck with two of them!
