By the way, the original Rogue, the namer of the roguelike game genre, was
originally developped on a PDP-11 running Unix V6.

For an expanded answer to the original question: 

http://gunkies.org/wiki/PDP-11#Unix_based_Operating_Systems

Operating Systems supported:

Unix 1 to 7.
System III
BSD 2.x
RSX-11
RSTS/E
RT-11

The site mentions that BSD 2.11 would be the best fit for loading Unix on a
PDP-11 nowadays.
