I have found some plotter pens. Ons pack says Calcomp 104x, 1023. The other
I can't trace. They look like they clip into ring. Pics here.

I have a few more of the Calcomp, packets of the un-branded sort.

To all,
Some 20 years ago, I led the Computer History Museum's restoration of an
IBM 1620 Model 1 computer. Our team was successful in both bringing the
machine back to life and collecting a massive amount of manuals, books,
and software for the machine. Most notable the John Maniotes
collection. I can safely say that CHM has the largest collection of IBM
1620 material in the world.
We are still looking for IBM 1620 Model 1 manuals to add to collection.
Please let me know if you have anything that we might be missing.
In the past 2 years, several people have been writing simulators for the
IBM 1620 Model 2 that go well beyond SIMH's instruction-level
simulator. These simulators are based on the logic diagrams of the
machine and implement unusual corner cases as well as documented
functionality. One of the simulators has a text-based front panel while
another one has a full true-to-life graphical front panel. It's not my
place to formally announce either program, that's for the creators to do
once they complete their implementations. I've been consulting with the
engineers and am reaching out to the broader community for help.
What they need, and CHM would be very interested in adding to its IBM
1620 collection, is original software specifically for the IBM 1620
Model 2. Of particular interest are the IBM 1620 Monitor II and IBM
1620-2 diagnostics, but any Model 2 software would be helpful to their
efforts.
Please let me know if you have and IBM 1620 Model 2 software or manuals.
Thanks,
Dave Babcock
Hi guys,
I have 8 "new" Chips from Signetics, they are labeled:
S7536
N8220B
and on the backside between the pins "8220".
Does anyone know what they do? My search with google and
in the 1976 Signetics Date Manual (from Bitsavers) wasn't helpful...
Thanx in advance,
Holm

If anyone wants any DEC gear brought up to wcfmw, please contact me off
list.
If anyone is driving out from the NJ area, I have a few pieces of audio
equipment I need to get transported to IL.
I also collect US and foreign coins and currency, and am interested in
buying or trading for DEC items.
Thanks, Paul
Classic computers have a value in our capitalist society. Take the Apple-1:
Its value can be in the $100,000s. One is for sale now: ~ $200,000. Next
seems to be the Kenbak-1 valued somewhere around $50,000. Now, I’m not
suggesting money is the epitome for evaluating our hobby but it goes a long
way to explaining its longevity.
Happy computing.

Add. I'm unable to get the output from your site but hope to contribute in
some small way.
I finally got an Emacs running on v7--it's on misspiggy at LCML now as "ue".
It's Microemacs 3.6; what I did was to clone
https://github.com/troglobit/MicroEMACS and check out the first commit.
Some experimentation later, it had the usual problem with v7 and DEC
linkers that not all the function names (er, more generally exported
symbols, but in this case, function names) were unique in the first 7
characters (which is 6 if you're working with DEC OSes). So a bit of sed
later and I had something that built, linked, and appears to run with
TERM=vt100 set.
Arrow keys, naturally, don't work, but C-b, C-f, C-p, C-n do.
I think I'm going to just make a GH repo of it, but I'm happy to send the
tarball, or tar.uue, upon request. I find UUCP kinda fragile on my simh
installation, and I don't know how to get to Miss Piggy's (although the
uucp commands are there), so, well, uuencoding, a pasteboard buffer,
iTerm2's "Paste Slowly", and cat will work as a file transfer mechanism.
Now I'm going to run over to TUHS and announce the same.

While I have a couple Apple ]['s I really don't do much with them. Haven't
even turned one on since I retired from the University in 2015 and they
came home .
Wouldn't take an Apple 1 as a gift but I, too, would love to have an IMSAI
and a SWTPC 6800.

I have heard rumors of one "fredmacs" which is a more-or-less emacs that
will run on PDP-11 v7 Unix. Since I've gotten "s" onto v7 and behaving
mostly happily, now I'd like an editor I actually _like_ rather than
_tolerate_.
Does anyone know where to find the fredmacs sources?

Hi all,
I just came across pictures on the LCM website about their SDS Sigma installation there.
On the pictures, one can see 10-platter disk packs in the corner and stored on the disk drives.
Did the LCM ever had these in operation, either for data retrieval or even demo purposes?
I know of the Jim Austin Computer museum where they fixed a CDC 9766 drive but it suffered
a head crash after a few hours according to their description which led to giving up the operation
of these drives.
Greetings,
Pierre
