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.

Cheers all, Warren

Have these been OCR'd yet? Or just the scans?

What is everyone's experience with source code OCR?  I have tried it a
few times, and the resutls haven't been that good.  In my experience
it's about as much effort as typing it manually.

I'm working on a GRAPHICS-2 simulation so we can run Space Travel.
Obviously I'd like a machine readable version of the program.  However,
I'm not volunteering to do all the typing myself.

I use Office Lens with my móviles. Impressive results (for good) in some
moments.

Doug had an excellent comment on OCR:

A few people have asked me if the scans have been OCR'd yet. The
answer is no. Also, the input is not easily recognisable with
automated OCR technology: I've already tried. We will have to
hand transcribe the files as we did with the first half.

There is already a PDP7 Unix mailing list from the past resurrection
effort. If you'd like to join and help out with the transcribing,
please e-mail me and I'll add you to the list. The list archive is:

Oh, the PDF is searchable.  Very nice.  Page 109.

Searchable means at least some ocr uas happened.

I have had at best mediocre results trying to ocr the cb unix file. Maybe
these will be different.

[TUHS] File system salvager, "salv"

My attention is drawn to "salv".

There are these V2 and V3 man pages.
https://www.tuhs.org/Archive/Distributions/Research/Dennis_v2/v2man.pdf
https://www.tuhs.org/cgi-bin/utree.pl?file=V3/man/man8/salv.8

I see a V3 man page for dcheck, but nothing for icheck until V6.

So it appears before fsck, and before icheck etc, there was salv, the
file system salvager tool.  Some quick searching reveals that CTSS,
Multics, and ITS all also used the term salv and/or salvager for the
corresponding program, so there's ample precedent.

Re: [TUHS] New: The Earliest UNIX Code - From the Collection of the Software History Center, Computer History Museum

[Lyle Bickley]

I didn't do all the work - I'm just a volunteer and "messenger" from the
Computer History Museum (CHM).

The real work was done by David C. Brock, who is a historian of technology and
director at the CHM Software History Center. 

Cheers,
Lyle
