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/ :-)
Cheers,
Warren
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?

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?)

Cool just downloaded it.... seems whoever put it together really liked
gzip... ;)

Yeah, that'd be great! I've heard it's v6 with lots of bsd.. But it'd be cool to look at it!

I can put up a tarball of the stuff I have for you, if you want.

I hate to say it but the demos stuff I found here
http://pdp-11.ru/mybk/pdp11/DEMOS.RAR
Seems to not include full source... I haven't gotten SIMH to boot the thing,
nor some of the... "interesting" Russian PDP-11 emulators.. I ran strings
through the disks, and I got some basic header files, oddly all in English,
but no kernel or system source code, just some Fortran example....
I'll have to ask someone in Russia if they have any real solid leads on
DEMOS... It seems that once the Soviet Union fell, everyone abandoned DEMOS
for any of the BSD's...

I found some disk images online that say it's for the PDP-11 version... let
me see what I can pull from them for you.
The UWISC stuff is here:
