The quick-'n-easy solution I found when I needed to model some parts
for a keyboard was https://www.tinkercad.com/ - needs a modern-ish web
browser and a modestly beefy system tho.
I've got a very nice SV-328 that's had the sad misfortune of having the
"K" key rather violently removed. (https://i.imgur.com/IxBIQTj.jpg)
Can someone point me to where I could obtain a replacement key top and
post?
Thanks!

I just installed Ultrix-11 3.1 using the ultrix31.tap file from
https://pdp-11.org.ru/files.pl?lang=en
which is the location from the comments in Stephen's Machine Room video on
YouTube that I think started this thread.
It installed just fine, but just like the video, I ran out of space on /usr.
How can I make a larger /usr partition? Is it possible to do this at
installation time? There did not seem to be an option for this. Can it be
done by using an additional disk? That would seem likely, but not what a
system manager back in the 70's or 80's would expect to need to do,
especially as there is a relatively large amount of space left to create
/user1.
I noted the options for installing software using soft links to other
locations. Was that the preferred method when installing additional
software?
Any help would be greatly appreciated.
Cheers

Bitsavers has 6.3 (thank you Al) but I'm trying to push my luck and find
8.1 for this XP421CH Xterm. Anyone know of where it can be found?

Hi cctalk,
I'm looking to replicate the 24-contact connector system that IBM used on
SLT and MST cards for many years. Has anyone done this before?
The best photos of this connector that I can find online are on this page:
http://techandtrouble.blogspot.com/2014/04/happy-50th-system360-pt5-anatomy…
I haven't searched Bitsavers documentation extensively for IBM
specifications, but I've seen some details around page 54 of this document:
http://www.bitsavers.org/pdf/ibm/logic/SY22-2798-2_LogicBlocks_AutomatedLog…
I'm interested in reproducing both polarities of this connector: plug and
socket. Also, even though the most familiar use of this connector is for
board-to-board interconnect, I'm most interested in wire-to-board
interconnect. IBM used this method for DC power connectors in its 5100,
5110, and 5120 computers. Here are images of this specific connector:
http://stepleton.com/connector/
taken as still images from a YouTube video on the IBM 5120 by Jerry Walker (
https://www.youtube.com/c/JerryWalker-JMPrecision/videos).
I've designed and built a device that monitors DC power supply voltages for
overvoltage and undervoltage excursions and cuts off all power rails if any
voltage goes out of spec. I hope to use it to protect my own IBM 5100 from
major power supply faults like the one CuriousMarc encountered with his
9825T:
https://www.youtube.com/watch?v=b-eN93L6yX8
In order to put my device between my 5100's power supply and the logic card
backplane, I need to recreate a plug and a socket so that I can fashion a
cable that goes out to my device. If anyone has created dependable modern
versions of these connectors, would you mind sharing any pointers?
Thanks for any help,

Yes and no. There is the TA11 Magnetic Tape Cassette System, which used the
TU60 Dual DECasette Transport (I need to create a page for that in the
CHWiki), but it uses a special controller card, the TA11 Magnetic Tape
Cassette controller:
https://gunkies.org/wiki/TA11_Magnetic_Tape_Cassette_controller
There is a small cheap tape system which used a stock serial interface to talk
to the computer, the TU58, but those used DECtpe-II cartridges, not standard
casettes.

I just saw there is an ME11 Memory Expansion unit on eBay (not mine), stamped 'M11'.
https://www.ebay.com/itm/114941479208
Until seeing this one I had not heard of any other units out there apart from the one I recovered
(ex-BHP steelworks) a few years ago. Mine was connected by a flexprint cable to a rebadged PDP-11/15.
If anyone here ends up with it, I have an OpenSCAD model of the Mazak bracket p/n 1211221 that holds
the regular 5-1/4" DEC fascia panel onto the front of the H-909 cabinet this unit uses.
This is the same cabinet as the slimline PDP-11/05 and to be honest when I found the ME11 that's
what I thought it was, and that the console and CPU boards were missing. I then found the fascia panel
with the original brackets close by, and it fitted exactly.
I've printed a few from PET and they work as well as the originals (including the threaded hole), so
I could do a few more for whoever gets the eBay one should they want them.
I am slowly scanning the ME11 print set too as I've not found any online copy out there so far.
Steve.
Hi all!
The book about John Nash ("Beautiful Mind'")[1] mentioned that he wrote
computer programs:
"Edward G. Nilges, a programmer who worked in Princeton University?s
computer center from 1987 to 1992, recalled that Nash ?acted frightened and
silent? at first. In Nilges?s last year or two in Princeton, however, Nash
was asking him questions about the Internet and about programs he was
working on. Nilges was impressed: ?Nash?s computer programs were
startlingly elegant.?"
Has anybody seen them?
Are they available somewhere for downloading?
Wondering...

Once I was in the business of making 3D file format translators,
and I still have code that runs under Windows that can read
and write Movie.BYU format.
