<Someone can correct me if I'm wrong but ISTR that the dateset at startup

<year as well.
You are correct. I works.
Now I have four systems running some form unix (Linux, Venix, Ultrix, and
V7) and their resemblence at the user level is good but at the sysadmin
they might as well be from different worlds. Granted, they are different
platforms.

Yes, of course you will. You will also have to kill anybody who attempts

In article by Ken Wellsch:
[ Ken confirms that the Xinu distribution for the PDP-11 includes
the sunchip package, which is a C compiler and assembler, all
written in C ]
Chip is the "Cornell Hypothetical Instructional
Processor." It has a
PDP11-like architecture and supports virtual memory.
description can be found in the technical report:
To run the simulator for this machine, you need a 4.1bsd (or newer) Unix
system. The distribution also contains a development environment for CHIP
containing a C compiler, assembler, loader and various other tools. To
run the development software, you currently need Digital Equipment Corp.
VAX computer. However, with minimal effort, all of this software should
be able to run on any host with UNIX.
[...]
----------------------------------- end of README --------------------
P.S. As I suspected and feared,
% diff -r Trees/V7/usr/src/cmd/c Xinu/src/cmd/cc11
indicates the C compiler provided in all these archives (Xinu,
CHIP, sunCHIP) are directly derived from the V6/V7 compiler.
So is the DECUS C compiler, I hear. Is there any native C compiler
for the PDP-11 which isn't derived from V6/V7?

Where might I obtain the sunCHIP C compiler for comparison purposes?
You need to fetch the Xinu distribution. I haven't got time to unpack the

# Can anybody tell us the correct origins of the DECUS C compiler?
One thing I can tell for sure: the DECUS C Compiler and the K&R CC are
completely different in their origins. I'm about 90% sure the DECUS XCC
is written in MACRO-11.
The reason I'm so sure is because we were looking at a suitable C compiler
to run on our 11/34 back in 1989 and we first mungled with the DECUS XCC.
But this one had several deficiencies, among them I remember lack of blocks
within functions, local variable initialization, difficulties with typedefs/structs.
Maybe, Harti could tell more.
We were looking into Johnson's pcc, but this one turned out to be a too big
piece of work and to slow to run on our 128 KWord machine.
Harti tried to port the Whitesmith CC from RT11, and it ran, but there were
deficiencies with the RT emulation, so we dropped that.
Finally, we took the K&R UNIX CC and reworked it so that it would pass the
DECUS XCC to produce the stage one. We wrote our own unix assembler supporting
the RSX object file format from scratch. Later, we recompiled the K&R CC on
RSX with itself. This system became our workhorse for the next 2 years, the
compiler is still amazingly fast, both in terms of runtime and the code being
produced. (Quoted: Harti)
So here are the 4 different original sources of C compilers for the 11, though,
admittedly, 2 of them would run on DEC's original OS, not on UNIX, which I guess,
makes them somewhat irrelevant to PUPS. Am I right here ? (Where do we draw the
boundary ?)

Hey, hey! Gotta make a reference to the original artwork! :-)

I should say (and Joerg reminds me) that he & Harti sent me a t-shirt
a couple of years ago with a copy of boot/login sequence of V7 on the
front, and the section of the V6 kernel with the comment above on the
back. I wear it quite a bit, and my fiancee likes it too, but probably
for other reasons.
Thanks Joerg!

The /* You are not expected to understand this */ is also on the second
page of Peter Salus' A Quater Century of UNIX, explaining a lot of folklore
behind the UNIX history, including things like "a tape was found on the
street to contain ...".
The "contamination" term is (as far as I can tell) originated at Berkeley.
When USL sued UCB for violating AT&T UNIX copyrights, it became apparent,
that anyone ever having had a look at the original sources would be "infected"
and be disallowed to distribute code that vaguely resembles anything in UNIX.
Kirk McKusick then showed up with "Mentally contaminated" stickers for everyone
attending the 4.4BSD Kernel Internals course at the Winter 1993 USENIX
Conference, since he would present us - guess, what - source code! (of 4.4BSD)
I still have the sticker somewhere in my collection.

Yes, I'd love to lay my hands on the `50 bugs' tape. For those who don't
have Peter Salus' book (get out there & buy it!), this tape had fixes to
V6, but the lawyers prevented Bell Labs from distributing it. So, someone
`found' it lying in the street and that's how the patches found their way
out of the Labs.
The "contamination" term is (as far as I can
tell) originated at Berkeley.

I still have the sticker somewhere in my collection.
I got one of the `Free the Berkeley 4.4' t-shirts. Good stuff.
Kirk's the guy who is working on making the 4.xBSD releases available on CD.
Please don't hassle him about it; I'll do that 8-)
I've informed him that the SCO license covers 32V. Therefore, a lot of
people will soon become eligible to receive 4.xBSD.
