hi all,
The recent flurry of activity in early pre-C UNIX for an 11 with a
small memory got me back to working on my 11/05. So far I've
identified two nasty problems with the data paths board, the M7260.
One of the 8266 MUX chips looks like the plastic boiled and bubbled
and circuit board is discolored underneath it. I'd welcome both
sources for replacement chips and techniques for replacing it.
Additionally there's a lifted and broken trace on the non-component
side of the module near the F edge connector. Any sugestions for
repairing a damaged trace would be welcome.
Lastly, I'd just as soon use a DL11W in the 11/05 rather than go to
the trouble of setting up an external clock to feed the on board UART.
I can get both 9600 baud and RS232 from the DL11W instead of 2400 baud
current loop from the built-in interface. I haven't yet found the
jumpers to remove/install that would disable the built-in console
interface. There's also the LTC.
TIA,
Milo

Unix: Where /etc/init is job #1.
Hi.
I'm reading TCP/IP Illustrated - for the first time; talk about slack! - and
noticed Stevens used BSD/386. I remember seeing in DDJ in the early '90s ads
for various software-plus-source from a Texas repackaging company, and they
had BSD/[386|i|OS] at various times for $1k.00.
That was then - this is now. Is it likely, or even possible, that BSDi the
company would be ready to consider BSD/386 and such early releases, legacy
that could be donated to TUHS? And if so, who should we contact, to ask?
Thanks
Wesley Parish

All Simh version 3.8-0 has been released by Bob Supnik. It now has all the
support that we need to run 1st Edition UNIX. In our Subversion repository,
I've updated the Readme file and the simh.cfg file to match the new simulator.

Hello.
Very interesting article from http://arstechnica.com here:
http://arstechnica.com/news.ars/post/20080501-deluded-sco-ceo-on-witness-st…
A quote from that article:
"Greg Jones, VP of Technology at Novell, was called as a witness. Jones
was asked if SCO ever told Novell that it would sue Linux users. He
said, "No, never that specific." When asked if SCO notified Novell under
the Asset Purchase Agreement Amendment 2 that it would enter into a
license with Microsoft, he said, "No."
Jones testified that SVRX code is in Solaris and that he had discovered
several cases of this. At that point, Novell entered into evidence at
least 21 examples of OpenSolaris code that had been taken from the SVRX
code base (one such example can be found on the OpenSolaris web site)
and re-licensed under Sun's open-source CDDL license.
He further testified that the agreement between SCO and Sun was
"extraordinary" in allowing a move from a proprietary license to an
open-source license, and if Novell had been asked, it would have
prevented SCO from entering into that agreement. He said the same thing
regarding the Microsoft agreement with SCO, as well as the agreement
between SCO and Computer Associates."
And then this pearl:
"SCO argues that it was not authorized to execute license agreements and
that interested third parties such as Sun and Microsoft should get their
money back, but it says that Novell is not entitled to hold the money in
the interim. If you purchased a license from SCO that was unauthorized,
the argument is that you'll need sue them to get it back. Since SCO is
currently in bankruptcy proceedings, that could be difficult."

With the successful restoration of Unix V1, I was thinking of other
operating systems that could be restored in a similar way. The most
historically significant would probably be CTSS. The SIMH IBM 7094
simulator has everything necessary to run CTSS implemented already,
although the CTSS-specific stuff is untested (since as far as I know,
nobody has booted CTSS in it yet) and may need some patching.
There are several tapes of listings (for almost all of the system), and
a few tapes of binaries (one with supervisor binaries, and one with
"standalone" utilities, but nothing with user-mode programs) available.
The listings need to be converted back into source that can be assembled
or compiled. Part of this can be done automatically (I have written some
dumb scripts to do this), but there will likely be quite a bit of manual
editing involved. There is nothing to be OCRed, since everything is on
magtapes.
Most of the source is either assembly or MAD (an Algol-58 dialect), with
a few files in AED (another Algol dialect, for which no compiler appears
to have survived). Restoring the assembler stuff should be easy (there
exists a cross-assembler which would work), but restoring the MAD stuff
will be a little bit harder. There is no cross-compiler for it (there is
a compiler that runs under IBSYS, but it is probably just for an IBSYS
target, and I'm not sure if anyone has even figured out how to run it).
The AED stuff will have to be rewritten in MAD (which shouldn't be
especially hard, since AED and MAD are somewhat similar). Only a few
non-essential programs are written in AED.
I think that all (or at least most of) the stuff required for booting is
written in assembler, so the best way to get it working would be get a
minimal system booting (I suspect all that is necessary is the
supervisor, so the binaries on the tape might be of use), and run the
CTSS MAD compiler under it to compile all the MAD stuff (which includes
many of the "core" commands).
I'm not sure what the best way to get stuff into a filesystem is. The
standalone utilities run under FMS, and there is no bootable FMS tape.
There is a version of FMS that runs under IBSYS, but for some reason, it
returns an error when attempting to load the utilities off the tape.
It is probably possible to patch it to fix that bug, though. It would
also work to write utilities that run on the host system, much like what
was done for Unix V1 (although I think that fixing the bug in FMS would
probably be easier).
Maybe I should start a Sourceforge project.
Another, much simpler, system which might be possible to restore is
MUMPS-15, for which a PDF of a paper listing is available on bitsavers.
Restoring it would probably just be a matter of OCRing, correcting, and
assembling it (and maybe writing a bootstrap).
