Currently I've only got an older laptop at home still running Windows 10
Pro. Mostly I use a company provided HP ProBook 440 G7 with Windows 11 Pro.
I installed WSL2 to run Ubuntu 20.04 if only because I wanted to mount UFS
ISO images đ
Still employed I have access to lots of UNIX servers, SCO UNIX 3.2V4.2 on
Intel based servers, Tru64 on AlphaServers, HP-UX 11.23/11.31 on Itanium
servers. There's an rx-server rx2660 I can call my own but even in a
testroom I can hear it. Reluctant to take home. My electricity bill would
also explode I think.

I'd like expand on this, since I never heard about STOPGAP or SOS on the
MIT PDP-6/10 computers. TECO was ported over to the 6 only a few weeks
after delivers, and that seems to have been the major editor ever since.
Did you think of the SAIL PDP-6?

Yes; some of the history is given here:
An incomplete history of the QED Text Editor
https://www.bell-labs.com/usr/dmr/www/qed.html
Ken would have run into the original on the Berkeley Time-Sharing System; he
apparently wrote the CTSS one based on his experience with the one on the BTSS.
Oddly enough, CTSS seems to have not had much of an editor before. The
Programmer's Guide has an entry for 'Edit' (Section AH.3.01), but 'edit file'
seems to basically do a (in later terminology) 'cat >> file'. Section AE
seems to indicate that most 'editing' was done by punching new cards on a
key-punch!
The PDP-1 was apparently similar, except that it used paper tape. Editing
paper tapes was difficult enough that Dan Murphy came up with TECO - original
name 'Tape Editor and Corrector':

> Will had asked -- how did people learn to use reg-ex?
I learned it from reading the 'sh' and 'ed' V6 man pages.
The MIT V6 systems had TECO (with a ^R mode even), but I started out with ed,
since it was more like editors I had previously used.

Subject: [TUHS] RIP Niklaus Wirth, RIP John Walker
Earlier this year two well known computer scientists passed away.
On New Yearâs Day it was Niklaus Wirth aged 90. A month later it was John Walker aged 75. Both have some indirect links to Unix.
For Wirth the link is that a few sources claim that Plan 9 and the Go language are in part influenced by the design ideas of Oberon, the language and the OS. Maybe others on this list know more about those influences.
For Walker, the link is via the company that he was running as a side-business before he got underway with AutoCAD: https://www.fourmilab.ch/documents/marinchip/
In that business he was selling a 16-bit system for the S-100 bus, based around the TI9900 CPU (which from a programmer perspective is quite similar to a PDP11). For that system he wrote a Unix-like operating system around 1978-1980, called NOS/MT. He had never worked with Unix, but had spelled the BSTJ issues about it. It was fully written in assembler.
The design was rather unique, maybe inspired by Heinz Lycklamaâs âSatellite Processorâ paper in BSTJ 57-6. It has a central microkernel that handles message exchange, process scheduling and memory management. Each system call is a message. However, the system call message is then passed on to a privileged âfat kernelâ process that handles it. The idea was to provide multiprocessor and network transparency: the microkernel could decide to run processes on other boards in the same rack or on remote systems over a network. Also the kernel processes could be remote. Hence its name âNetwork Operating System / Multitaskingâ or âNOS/MTâ.
The system calls are pretty similar to Unix. The file system is implemented very similar to Unix (with i-nodes etc.), with some notable differences (there are file locking primitives and formatting a disk is a system call). File handles are not shareable, so special treatment for stdin/out/err is hardcoded. Scheduling and memory management are totally different -- unsurprising as in both cases it reflects the underlying hardware.
Just as NOS/MT was getting into a usable state, John decided to pivot to packaged software including a precursor of what would become the AutoCAD package. What was there worked and saw some use in the UK and Denmark in the 1980âs -- there are emulators that can still run it, along with its small library of tools and applications. âNOS/MT was left in an arrested stateâ as John puts it. I guess it will remain one of those many âwhat ifâ things in computer history.
A friend of mine has a DECmate-II word processor. It is in perfect
working order except for one thing. The field encoding the current
date/time has overflowed. It is impossible to set a date/time in the
21st century.
He says that the software in question is a version of WPS-8 for the
PDP-8. It should be possible to fix the date/time problem by dumping
the DECmate's ROM and disassembling the code. It ought not be too
hard to locate the date/time encode/decode routine and come up with a
fix to the time epoch problem.
Is anyone out there familiar with the DECmate-II software? Or, even
better, knows how to get its source code?
Advice greatly appreciated.

I've just uploaded a couple new items to archive.org that
folks may find interesting:
https://archive.org/details/5ess-2000-switch-es5431-office-data-base-1998https://archive.org/details/5ess-2000-switch-es5432-system-analysis-1998
Linked above are the ES5431 (Office Data Base Installation)
and ES5432 (System Analysis) training CDs as produced by
Bell Laboratories (Lucent era) for the 5ESS-2000 switch.
Among other things, these CDs contain a 5ESS simulator which
you can see a screenshot of here:
https://www.classicrotaryphones.com/forum/index.php?topic=28001.msg269652#mâŚ
I was able to successfully get it to run on Windows 98 SE in
a virtual machine, although did break one rule of archiving
optical media in that I didn't take iso rips. I intend to
throw an old FreeBSD hard disk in that computer sometime soon
and do some proper rips with dd(1). In the meantime,
this means using the above archives presents only a partial
experience in that the Training section of the software
appears to depend on the original discs being inserted.
In any case, the simulator interests me greatly. I intend
to do a little digging around in it as time goes on to see
if there may be traces of 3B20 emulation or DMERT in the
guts. I'm not holding my breath, but who knows. Either way,
it'll be interesting to play with. Thus far I've only
verified the simulator launches, but have done nothing
with it yet. Picked up Steele's Common Lisp (2nd Edition)
in the same eBay session so time will be split between this,
learning Lisp, and plenty of other little oddball projects
I have going, but if I find anything interesting I'll be
sure to share.
Given that Nokia is shedding 5ESS stuff pretty heavily right
now (or so I've heard) I have to wonder if more of this
stuff will start popping up in online market places. Word
over on the telephone forum is that some folks in Nokia
do have an interest in preserving 5ESS knowledge and
materials but are getting the expected apathy and lack of
engagement from higher ups. Hopefully this at least means
Nokia doesn't mind too much this stuff getting archived if
they don't have to do any of the footwork :)

On Wed Feb 23 16:33, 1994, I turned on the web service on my machine
"minnie", originally minnie.cs.adfa.edu.au, now minnie.tuhs.org (aka
www.tuhs.org). The web service has been running continuously for thirty
years, except for occasional downtimes and hardware/software upgrades.
I think this makes minnie one of the longest running web services
still in existence :-)
For your enjoyment, I've restored a snapshot of the web site from
around mid-1994. It is visible at https://minnie.tuhs.org/94Web/
Some hyperlinks are broken.
## Web Logs
The web logs show me testing the service locally on Feb 23 1994,
with the first international web fetches on Feb 26:

## Minnie to This Point
Minnie originally started life in May 1991 as an FTP server running KA9Q NOS
on an IBM XT with a 30M RLL disk, see https://minnie.tuhs.org/minannounce.txt
By February 1994 Minnie was running FreeBSD 1.0e on a 386DX25 with 500M
of disk space, 8M of RAM and a 10Base2 network connection. I'd received a copy
of the BSDisc Vol.1 No.1 in December 1993. According to the date on the file
`RELNOTES.FreeBSD` on the CD, FreeBSD 1.0e was released on Oct 28 1993.
## The Web Server
I'd gone to a summer conference in Canberra in mid-February 1994 (see
pg. 29 of https://www.tuhs.org/Archive/Documentation/AUUGN/AUUGN-V15.1.pdf
and https://minnie.tuhs.org/94Web/Canberra-AUUG/cauugs94.html, 10am)
and I'd seen the Mosaic web browser in action. With FreeBSD running on
minnie, it seemed like a good idea to set up a web server on her.
NCSA HTTPd server v1.1 had been released at the end of Jan 1994, see
http://1997.webhistory.org/www.lists/www-talk.1994q1/0282.html
It was the obvious choice to be the web server on minnie.
## Minnie from Then to Now
You can read more about minnie's history and her hardware/software
evolution here: https://minnie.tuhs.org/minnie.html
I obtained the "tuhs.org" domain in May 2000 and switched minnie's
domain name from "minnie.cs.adfa.edu.au" to "minnie.tuhs.org".
Cheers!

P.S. I couldn't wait until Friday to post this :-)
After learning of Dave's death, a professor I very much enjoyed as a U
of Delaware EE student, I came across this page
https://www.eecis.udel.edu/~mills/gallery/gallery9.html
This reminds me of his lectures, the occasional 90 degree turn into who
knows what, but guaranteed to be interesting. And if anyone has a UDel
Hollerith card they're willing to part with, please get in touch. I
have none. :-(

Howdy folks, just finished an exciting series of repairs and now have a DEC VT100 plumbed into a Western Electric Data Set 103J. I was able to supply an answer tone (~2250Hz) at which point the modem began transmitting data. I could then pull the answer tone down and the connection remained, with keypresses on the VT100 properly translating to noise on the line.
Really all I have left is to see if it can do the real thing. I'm keeping an eye out for another such modem but in the meantime, is anyone aware of any 300-baud systems out there in the world that are currently accepting dials in? I don't have POTS at home but they do at my music practice space and if there is such a machine out there, I kinda wanna take my terminal and modem down there and see if I can straight up call a computer over this thing.
I've got other experiments planned too like just feeding it 300-baud modem noise to see if I get the proper text on the screen, that sort of thing, but figured this would be an interesting possibility to put feelers out for.
On that same note, if I get another modem and a stable POTS number to expose it via, I'm considering offering the same, a 300-baud UNIX-y system folks can just call and experiment with (realistically probably a SimH machine with the pty/tty socat'd together)
