Thanks for looking. Tomorrow I will visit our storage facilities (aka
converted barn) and I will then look through my heap of manuals and
schematics but I have no remembrance  of any RC11 manual.

The V8  (
talks about RC11 suport for example on page 2-6.

BTW. Speaking of dumping. Now that I have a TC11 / TU56 that seems to be
working, what is the best way to dump 18 and 12 bit tapes? Is there some
PDP-11 OS that can do it or is it assembly programming required? I had
hopes that RT11 had such features but it doesn't seem like it could read
all 18 bits.

Has this already been done? Maybe I can spend time on other things than
re-inventing the wheel...
