This is a working dsc 200 driver. It has bugs. If you use it
in a vanilla fashion (no DSBOFF) it works. I don't think anyone
has tried DSNODISK. The bugs are in DSBOFF, if you look at the
code you can see what is wrong pretty easily. I plan to fix it
soon but haven't had the time yet.

The code for pdp11 was mostly gotten from Rob Gross of Eastman
College. He wasn't including all of the code from physio and so
I put it in (they don't have much space because they have an
11/34). I have no way to test that part out.

NB: the dacs don't work all that well on our 11/780; we get
ZERO UBA VECTOR's. We are hoping that this problem will go away
when the 11/55 arrives. If you are going to use your dacs on
a vax: GOOD LUCK.

If you can reach me via either network please let me know so I
can send you updated versions of the driver.
