Jon,
I have an Emulex QD21 that I could part with. I was hoping to attend VCF MW but it looks very doubtful at this point. I also have a spare DEQNA or DELQA. I have not tested these boards to verify that they work although I could test the ethernet boards on a PDP-11. Hans-Ulrich Hölscher mentioned work he did testing MicroVAX II transfers with Lee Gleason’s MicroVAX I project to transfer disk images on bare metal (no-OS) MicroVAX systems. I think that would be your best bet to recover your ESDI disk. If you don’t have any luck at the VCCF MW getting what you need, send me an email and we can work something out.
Best,
Mark
FYI, SDF retro computing and home brew exhibition is scheduled for September 30 to October 1 in Seattle WA . Link to the exhibit is at https://sdf.org/icf/ and https://icm.museum/

Have you considered sqlite3? It's a SQL engine, but the backend is just a
file. So it doesn't support concurrent access by multiple users, but if
that's not a concern, it gives you the ability to do real SQL queries
without the bother of setting up an RDBMS.

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.
