A while ago, I heard someone (I can't remember who) say that he had a paper listing of (at least part of) PDP-7 Unix. How much is there in the way of surviving listings of PDP-7 Unix (if any)? With all of the discussion of OCRing the V1 Unix kernel listing, I was wondering if something similar could be done with PDP-7 Unix if enough listings have survived (which is sort of unlikely, but you never know).
