I have no doubt that the commentary was produced with the V6 nroff.
It has the look of machine-formatted text about it, although it was
clearly printed on a constant-width line printer of the time.

Now, were anyone so truly perverse, they might take the latex and
convert it into nroff/troff. :-)

Thus returning to the original form in which it was prepared. There's
an appealing circularity and feeling of having come full circle to
that...

Actually, I'm surprised that someone (presumably John Lions) re-wrote
the nroff into LaTeX - it would seem easier to have just used troff
for the book.

In order to get that 'original' feel, you'll need to find an
appropriate DECwriter (LA120?).  Remember to hand-write the page
numbers and draw in the lines (and maybe boxes) in chapter 23 by hand.

Whilst you could re-create the appropriate 7x9 (I think) font for a
modern printer - though that will be missing the feel of impact
dot-matrix output: random variations in density and missing dots.

Personally, I think that is over-doing it.  Text is _far_ easier to
read when it's properly typeset using a good looking font (that
includes descenders) at high resolution (>600dpi).  I believe the
visual appearance of the original notes was limited by the technology
available to John Lions in 1977, rather than a deliberate decision to
produce low quality output.

Doing so would be a major Waste Of Time.  This fact, in combination with
the "appealing circularity" just mentioned makes it highly likely that
it *will* be done by a Graduate Student somewhere .... :-)

It was last time I looked.  Today I seem to have misplaced my copy.
Just checked AddAll book search, the reprint of the Lions book has
become a rare collectable, and is selling for about $100.  Oh, well,
somebody bid a VT100 up to $355 yesterday.

Some people mentioned it being out of print.  I was wondering, has anyone
tried purchasing it from

    http://www.peer-to-peer.com/catalog/opsrc/lions.html

They don't seem to have any indication on the web site that it is out of
print, and they have a link to it from their home page
(http://www.peer-to-peer.com/).

Somewhere I had a TeX source file of it that went round
alt.folklore.computers about ten years ago.  I took a brief look
yesterday but couldn't find it.  If I try harder, there's a good
chance that I will.  Would anybody be interested?

Latex source to the book was posted to alt.folklore.computers circa
1994.  I'm guessing that the poster (a "Leo") typed it in by hand
given the comments that came with the readme.

I'm amused that someone would use LaTeX to reproduce a manuscript of
dot-matrix source listings and roughly-typewritten commentary.

(No offence at all intended to Dr Lions; the genius was clearly all in

When you describe the notes as having been "roughly-typewritten" I think
that you may have been misled by the quality of the printer that was used.

According to the 'Acknowledgements' in Lions:

 'The co-operation of the "nroff" program must also be mentioned.
  Without it, these notes could never have been produced in this form.
  However it has yielded some of its more enigmatic secrets so reluctantly,
  that the author's gratitude is indeed mixed. Certainly "nroff" itself must
  provide a fertile field for future practitioners of the program
ducumenter's art.'

Not at all; "typewritten" means "written with type": fixed-width,
metal impact type on bars or wheels.  Surely I can't be the only
person on this list who remembers when hardcopy terminals were often
called "typewriters".

Hello from Gregg C Levine
Actually, no your not. I do. Even though my contacts with computer
technology was rather limited, until about thirty odd years ago, and
on and off, during the eighties. For example, a shop that my father
ran, which did typesetting, used a pair of teletypes to communicate
with the host. (Host wasn't a DEC system, he was a related unit.)

And surprisingly enough, one of their customers was AT&T, they sent
over a manuscript they were having problems setting using the exact
same methods being discussed here. 

My copy of the C manual, that all of us know who wrote, says it was
done that way as well.

The first 11/20 I used had a Tektronix 4002 Graphics terminal
with it.  This was a storage tube, vector addressable.  But it also
had a complete ASCII terminal emulator built in, with diode matrix
character generator ROMs.  Also the best keyboard I ever used,
with magnetically-operated reed switches.  The Tek terminal used
a specially modified KL11 terminal interface, which did serial
communication to the CPU at something like 100k characters/sec.
This made the hard-copy TTY-based editor really easy to use, because
it could repaint the whole screen in a fraction of a second.

Absolutely fabulous reading!

The best part, in my opinion, is that when he is walking you through the
code of a function and you come to another function call, he gives you a
short description (sometimes just a couple of words, sometimes a few
sentences) of what that other function does so you can just keep on
reading the one you're in.

Since most time-space tradeoffs were made in favor of saving space and
spending time (64k limit for all kernel code and data on the 11/40), the
code is fairly straight forward (for example, linear searches instead of
hash tables) once you grok the magic of process switching and how system
calls work, which Lions helps with a lot.

He also gives a brief introduction to enough PDP-11 assembly and
architecture, and C, to understand the magic.  I found it to be a very
pleasant read a few years ago and I plan to read it again one of these
days.

I'm pretty sure that by 6th Ed the system was mostly C, with only a
few assembly routines.

High-resolution bit-mapped graphics at any reasonable price came along
a few years after 6th Ed.  Unix.  Character-cell CRT terminals that
could display 72x12 up to 80x24 characters on a screen were available
in 1975, but were pretty expensive.

Instructions for booting "uv6swre" are contained in the file "simh_swre.txt".
To make things easier for myself, I did the following:
$ cp unix0_v6_rk.dsk rk0.dsk
and so on for 1, 2, 3.
This gives me copies of the distribution disks that I can work with
without losing the originals.  Then I made a startup file "run.conf"
to contain the commands for the emulator.  Here is the result of a

    I was looking through the old archives at the old UNIX Dennis Ritchie
submitted. I would like to know how to boot this. I can't seem to compile
the PDP emulator(s) with djgpp or a non-linux system. I can with my linux.
Dennis said this version of unix was compiled with assembly, then into C if
I'm not mistaken. Now the PDPs they were the machines with no monitors just
printer tty type output correct?

You are mistaken.  It's the other way around.  Traditional C compilers generate
assembly which is assembled into machine code object files which are linked
into an executable.

Depends on the PDP you are talking about.  The term "Programmed Data Processor"
refers to a large number of different systems.  Some are a small as PeeCees and
others filled entire rooms.
