Hey all,
Got an old PentiumPro AViiON DG/UX machine.
I was just wodering if anyone happens to have an old, unused machine like
that.
If so, please reply with details, as well as geographic location.
All shipping costs will be payed by me.
A cash reward is offered, if you are interested.
Thanks,

Hi,
A number of years ago I diverted a couple of PDP-11 systems which were
on their way to a skip. I believe they were in working condition and I
had always intended to clean them up and get them set up and running
again to see what it was all about. This never happened and I no
longer have the space to store them. As a result I'm offering them to
anyone who's willing to pay the shipping. They are located in Dublin,
Ireland.
There is some mild corrosion on some of the metal chassis and the
paint on the VDU casings is peeling off in place but overall I think
they will clean up well.
I think they are the MicroVAX II model and the consist of the PDP-11
chassis unit with a Ramstar T-1500 VDU and keyboard. Each one also has
a power distrubution box and they are configured for 120VAC operation.
There are also power cables (amongst others). I don't know what boards
are installed in them, but they did originally have tape drives
connected and were used to drive an inkjet printing system, so I
expect there is at least a tape controller and serial/parallel
interface in each of them.
Photos of everything are up on
http://sites.google.com/site/kevinphair/old-electronic-equipment/PDP-11
but unfortunately the cabinet units are no longer available.
If anyone is interested in these please get in touch soon as I won't
be able to keep them for much longer. If there's no interest in the
complete units, I'd also be happy to consider donating parts from them
to help with restorations or upgrade projects. I'm also open to
putting them in storage if someone wants to arrange collection at a
later date and is willing to split the storage costs.

If you used BSD before 1982, please let me know. Off-list is fine. I
have a few questions to ask to help provide examples in a history book I
am writing. Thanks.
I'm sorry if this has been done before, but I could find no indication
this was the case in the unix archive itself or in any of the months I
checked in the mailing list.
I have figured out what the first 50176 bytes of s1-bits are.
It is an "INIT Tape" as described in Dennis_v1 Boot Procedures(VII) and
Dennis_v3 bproc.8. It is apparently contemporary with s2 [all of the
files on it /etc/getty /bin/ls and so on match up exactly with their
counterparts on s2], and this would seem to make s2 the "/bin-/etc-/lib
tape" described in bproc.8.
Also - is there any other known copy of the "bos" bootloader? I'm
partway through hand-disassembling the one on the tape.
Anyone know how to get SIMH to send ^J for return?
Anyway - with the KE-11A enabled you need to use "d system sr" to set
the switch register [which must be set to 1 to cold boot, 73700 to come
up in single user mode, and any random value other than the special ones
0 57500 10 20 40 1 2 to come up normally]
The RF disk is not even large enough to contain the whole s2 tape, and
while even v1 supported mountable filesystems, there is no mkfs or mount
on the tapes.
I was looking at several NetBSD manual pages and saw that some HISTORY
sections had wrong .Bx or BSD reference like:
HISTORY
The xstr command appeared in 3.0BSD.
I looked at a few and saw this was in 4.4BSD manual pages. By the way,
when were these history sections added? (They aren't in 4.2BSD manual
pages. I should look at 4.3 before asking ...)
I didn't see any that refered to original Berkeley UNIX Software Tape
nor 2BSD.
But from looking at the 1BSD and 2BSD, I see:
apropos was in 2bsd
colcrt was in 1bsd but not in 2bsd
even though 2BSD iul, soelim, and ssp manuals referenced it
(why missing from 2BSD?)
colrm was in 1bsd but not in 2bsd
csh was in 2bsd (even 1bsd referenced the upcoming "csh")
ctags was in 2bsd, but as a shell script using ed
expand was in 1bsd and 2bsd
finger was in 2bsd
fmt was in 2bsd
from was in 2bsd
head was in 1bsd and 2bsd
lock was in 2bsd
last was in 1bsd and 2bsd
mkstr was in 1bsd and 2bsd
msgs was in 2bsd
printenv was in 2bsd
soelim was in first BSD and 2BSD
tset was in 1bsd and 2bsd
w was in 2bsd as finger -sf
whatis was in 2bsd
whereis was in 2bsd
xstr was in 2bsd
lastlog file format was in 1bsd and 2bsd (?? maybe different format??)
Any comments on the above?
Or is this simply because "2BSD" is not a operating system release per
se, so "3.0BSD" is correct?
But this makes me wonder if my 2BSD versions are newer than first
2BSD, so really 3BSD is correct for some of this.
I was going to ask a NetBSD list about this to fix these histories, but
decided to consult TUHS instead. Okay to change history to fix history?
:)
I don't know if this is interesting to anyone, but I thought I'd share that
386BSD will install on Bochs (although slowly, and it's prone to crashing),
however once the first patchkit is installed, it'll then run on Qemu!
(0.11.0, it seems the new bios layout of 0.12 is incompatible)
If anyone is interested, here is a link to a hard disk image that I've
prepared for Qemu:
http://vpsland.superglobalmegacorp.com/install/386BSD/bsd386.qcow2.gz
I run it like this:
qemu.exe -L pc-bios -hda bsd386.qcow2 -M isapc -net nic -net user -no-reboot
-m 256
And I can run lynx/irc as a test of the TCP/IP.
At any rate, I figure this kind of brings 386BSD back out of it's grave.
Is anything likely to happen to the status of various historical
Unices? Is Novell likely to keep the Ancient Unix license intact or
are they likely to lock things back up? Is there any chance that
SysIII and early SysV might finally get opened up? Does anybody have
any ideas here?
Mike

Hi, doesn't anybody know if there is a disk size limit on Unix 6? I wrote a
C program to create a file and it won't go above around 1.5Mb. It doesn't
crash or report any errors but the file size never exceeds around that size.
Maybe it's a disk size limitation?
Also, is it possible to add other devices? like using an ISO file perhaps.
Regards,
Andrew.

In the PDP-11 long is 32 bits, int 16 bits. And the PDP-11 is
determinedly little-endian if you stick to integers.
They got floating-point software right in 1971, but somebody screwed
up the word order when building FP hardware, which led to the
middle-endian mess.

Endian should not be a problem on a Intel/AMD processor. More likely your C
compiler is padding out the array for alignment. Try a '-fpack-struct' or
more safely, read the elements individually rather than a structure.
PS
To check, see what 'sizeof (struct ar_hdr_)' returns.

Bob Eager:
The 'ar' format of that vintage is trivial, and documentation easily
found. I wrote programs to read it back in 1976!
======
That's nothing. Either Ken or Dennis wrote such a program
years before that!
Warren even has a binary somewhere to prove it!
Seriously, it's a binary format, so I don't know that
it would be easy to process in awk. (At least not in
awk-classic; stuff that works only in ghootandwaveawk
is not all that interesting to me.) But the format is
simple, and any language new or old that can handle
binary data without tears should do.
If I didn't have an overfull plate already (and a
visit to the Auto-Electrocution Consultant tomorrow,
and one to the Canal Rooting Clinic Monday--proving
that one should follow Father's advice and Stay Away
>From The Canal, Neddie) it would be interesting to
collect the different specifications for ar headers
over the years, and write a small suite of programs
to read them. Perhaps in Python, just to be difficult.
(Why isn't there a language called Goon, Warren?)

Thank you! That works for me! I can now get correct sizes, names, and
data. I will clean up my little ar extractor over the next few days and
share it.
I want to look in some .a files identified by file(1) as "old PDP-11
archive".
Anyone know what tool I can use on a modern *BSD or Linux system to
extract the files from an "old PDP-11" ar archive?
GNU ar complains "File format not recognized". ar tells me:
ar: supported targets: elf64-x86-64 elf32-i386 a.out-i386-netbsd
coff-i386 efi-app-ia32 elf64-little elf64-big elf32-little elf32-big
srec symbolsrec tekhex binary ihex netbsd-core
But I have no idea how to try different targets. The GNU ar manual page
doesn't tell me much.
Or how can I use modern pcc or gcc to compile old pre-ansi ar.c?
Any suggestions?
Now I found a simtools.zip via http://simh.trailing-edge.com/ which is
"a collection of tools for manipulating simulator file formats and for
cross-assembling code for the PDP-1, PDP-7, PDP-8, and PDP-11." But I am
not sure if this is related. On that note, any ideas how to extract
files from a ".tap" file used by simh? (For now I use view or strings to
look at it.)
Thanks,
Jeremy C. Reed

I forgot to mention that I had a friend help me out, and he got SYSIII
running on SIMH.......!
I don't know if there would be any interest in this... I don't have a good
layout of 'steps' as it was so... chained from 32v, and from within itself
as it can't boot from the tape..
But I can supply a working disk image to anyone that wants it... or should I
send it to Warren 1st, and he can send it to all the ancient/sysv licenses?
sorry if i'm not all that coherent.

Several people have noticed that the web archive for the TUHS mailing list
had stopped at June 2009, which was when I migrated over to another box.
Looks like I had a perms problem, which should be now fixed, but this e-mail
is just to test that it is indeed fixed. Please ignore, and/or browse the
old mail at http://minnie.tuhs.org/pipermail/tuhs/ :-)

I was idly going through the 1999 Swartz memo
(http://www.groklaw.net/pdf/Swartz.pdf) wherein the source code of
RedHat 5.2 and UnixWare are compared for similarities. Most of those
are either bogus (just some #includes) or BSD-derived code. There is
one file which is concerning: drand48.c. The RedHat 5.2 file is very
similar to the UnixWare file, including headers and #ifdef's e.g.
/* @(#)drand48.c 2.2 */
/*LINTLIBRARY*/
/*
* drand48, etc. pseudo-random number generator
* This implementation assumes unsigned short integers of at least
* 16 bits, long integers of at least 32 bits, and ignores
* overflows on adding or multiplying two unsigned integers.
* Two's-complement representation is assumed in a few places.
* Some extra masking is done if unsigneds are exactly 16 bits
* or longs are exactly 32 bits, but so what?
* An assembly-language implementation would run significantly faster.
*/
#include <stdlib.h>
#ifndef HAVEFP
#define HAVEFP 1
#endif
As far as I can determine, drand48() arrived in SysVR1 and is defined
in the first SVID. It doesn't appear in SysIII, nor in the early BSDs.
Can anybody shed some light on drand48()? Could it have been written
elsewhere and made available e.g on a Usenix tape or comp.sources.*,
and included into SysV, or is SysV the origin of the code?
I'm sure the algorithm comes from elsewhere, e.g. Knuth, but the
strong code similarity is a worry.
Thanks,
Warren

Hi,
has someone ever tried to grab the old BSD sources where TCP/IP showed up
first and tried to use them to implement TCP/IP support for an old SYSIII
UNIX (ZEUS comp.)?
I tried this but I got scared by so much things which would need to be
done, inter-process communication, pseudo terminal support are just the
"starting points" and at the end it is also the kinda old C compiler
which has problems with the BSD sources (#defs to long for the cpp for
example)...
Has someone experience with this kind of topic?

All, I've spent a bit of time re-writing my "Unix Tree" website, where
you can browse the source code trees and compare related files. The
file comparison now uses colour to show similar lines.
The initial version is at http://minnie.tuhs.org/cgi-bin/utree.pl
but I will probably move the URL at some point.
Have a look and see what you think. I would gladly accept suggestions on
better or more accurate descriptions for each of the releases, also checking
of dates and other information.
Cheers,
Warren

Do repositories of MNOS and DEMOS operating system source
code or binaries exist? Do either of these run on simh
or other simulators? (were the PDP11 and VAX11 knockoffs
close enough matches to the originals?)
