Thanks Lyle. Yay, one of the two artifacts I've been waiting
for has dropped. This is the second half of the PDP-7 source
code "book", of which we've only had the first half from
Norman Wilson.

We now have the source to Space Travel, plus roff and sh, for
the PDP-7!

I've broken the single PDF from CHM into several sections and
put them here:

https://www.tuhs.org/Archive/Distributions/Research/McIlroy_v0/

09-1-35.pdf     user-mode programs: maths functions, ln, ls, moo,nm
10-36-55.pdf    user-mode programs: pool game
11-56-91.pdf    user-mode programs: pd, psych, rm, rn, roff, salv, sh
12-92-119.pdf   user-mode programs: space travel
13-120-147.pdf  user-mode programs: stat, tm, t (B interpreter?)
14-148-165.pdf  user-mode programs: ttt, un

We may also have the B interpreter, but I'm not sure about that.
