  Unix was done on the PDP-11 (something else
 before that, I think, but I forget what, and I think it was with the
 move to the -11 that it became portable enough to be ported instead of
 rewritten). 
PDP-7, though it was more of a "reimplementation" than a port.  The
PDP-11 code became (by v6 or so) portable enough that it was
subsequently made to run on the (sorta IBM 360-ish) Interdata 7/32 &
8/32, as well as VM/370, in the late 70s.
