However, the date at the bottom of each page of the source listing
is 3/17/72. My assumption is that the code was from that date, but that
the author of the memo spent a few months writing up the text that goes
along with it.
That's why I've been assuming that it was code somewhere between Version 1
and Version 2.

If possible, can you scan them at 400dpi or 600dpi? Those are much
more amenable to OCR than 300dpi.
Alternatively, if you can send me a hardcopy, I will scan it at 600dpi
and pass it along to bitsavers.

I have already noticed quite a few errors in the listing, so it's not
clear that the PDF was something that actually ran, or whether it had
been re-typed by somebody. So far, many of the errors I have found are
in the "cold" portion of it, so it may be that the "warm" code will
run properly.

It occurs to me that next year will the the 40th Anniversary of UNIX.
Is anyone planning any type of celebration? Perhaps the Vintage
Computer Festival?

All,
I'm sure I saw a PDF document a few years ago which was an early
UNIX kernel written in assembly code. I thought I had saved the document,
but alas I can't find it. Can anybody remind me where to get it, or
perhaps I was hallucinating!
Thanks,
Warren
I've started an SVN for the OCR'd results:
http://code.google.com/p/unix-jun72/
if anyone needs commit access email me your account name. I've already
assigned some blocks to people. If you want a block either claim it in
the notes.txt file or email me and I'll add it. Also if you have plans to
perform raw OCRs of large sections of the original doc, please let me know
or make a note of it in the notes.txt file.

I was researching various windowing systems for various reasons and I found
the mention of the V distributed sytem on the W article stub on Wikipedia:
http://en.wikipedia.org/wiki/W_Window_System
"W was originally developed at Stanford University by Paul Asente and Brian
Reid for the V operating system."
A few questions here: is V close enough to Unix to warrant winding up in
an "Other" category in the TUHS repository? Does anyone have a copy of it
(plus source if possible)? If so, who should I contact?
Thanks

I don't know what got into me. I decided to fire up a PDP-11. I have not
touched one of these for about 5 years. I've mostly been messing with
embedded Linux stuff.
The 2.11BSD patch archive has gone offline. Do you know if there is a
mirror of this somewhere?

Hi, Quing Feng,
at http://www.ba-stuttgart.de/~helbig/os/v6/pdp11 you'll find a detailed
description of the pdp-11 and its peripherals as needed for understanding design
and implementation of V6.
and at http://www.ba-stuttgart.de/~helbig/os/script/chapt2.4 you'll find a
description of the init process.
have fun,
Wolfgang Helbig

Hi QingFeng, I think you should join the PUPS mailing list ( see
http://minnie.tuhs.org/mailman/listinfo/pups ), as the people on
the list should be able to answer your questions.
Q1: The source code for V6 init.c is here:
http://minnie.tuhs.org/UnixTree/V6/usr/source/s1/init.c.html
Q2: I would browse through this area of bitsavers.org:
http://www.bitsavers.org/pdf/dec/pdp11/
Hope this helps, and if you have other questions please e-mail them
to the PUPS mailing list, so that we can all help you out.
Cheers,
Warren
