  Well, you really can't fault Berkeley for the AT&T restrictions 8-).

  2.10BSD wants a CPU with I/D space (which leaves out the '23) and float-
ing point (standard on '73, optional on '23), and (last I looked) at least
512Kb of memory. You might be able to work around any one of these individ-
ually, but 2 or more missing would be problematic.

  I just did a man ra on my 2.10 11/70, and it's there. I know of others
who have used the driver, although I don't use it here. Also, I believe that
TK50/70 support is being added. Of course, support is not the same thing as
being distributed in that format, but it should be possible to build a TK70
kit if needed.

  I think that's a bit harsh, given the above. Also, AT&T did offer a System 
III for the PDP-11 (_that_ was the Unix with no MSCP support) as well as a
System V (.1?) for the 11/70 only. I don't know if they still offer them, you'd
have to ask...
