the point is to run 1972 Unix on machine that was around

 Except that the MEM11
wasn't around in 1972. 
 I think the point here, is that much of the hardware that
is necessary
to run Unix V1 on an
11/20 is unobtainium.  Therefor, if one wants to run Unix V1 on 11/20
hardware, there is
going to be, by necessity, some compromises made.  Witness the previous
discussion on
the IBM 1620 where the core memory has been replaced with a modern
equivalent  in order
to allow it to work.  I view this in a similar vein.
I also think that given the historical significance of both Unix V1 and
the 11/20, this is a
worthwhile endeavor.
