There are no drivers that survived the uba changes. 
A fast look in the "DEC Peripherals Handbook" shows that the TS11
is a rather simple device. I think that a good work strategy is to
first break out Bertram's ts11-specific code from the current ts.c, 
then take a look at the uda.c to see how the uba structures cooperate.
If I get some spare time someday I may write a manual "how to write
Unibus device drivers".
