AIUI the owner is now in a nursing home.
Thanks to Justin Scott and a group of enthusiasts, rather than sending
all the stock to the scrappers, the store is occasionally re-opening
in an effort to sell as much as possible to collectors.
It's here:
https://www.computerresetdallas.com/contactus.htm
Address:
9525 Skillman St, Dallas, TX 75243
There's a FB group here -- an event will be posted whenever it's open:
https://www.facebook.com/groups/627459117730981/
(Last Saturday, next Saturday, for example.)
This is the GoFundMe for the owner:

There was a walkthrough on Youtube but it's gone. :-(
There's something for everyone. PDP, Vax, all manner of PCs including
PCJr, IBM portables, PS/2s, some complete and boxed, Amigas, NeXT,
TRS-80, terminals, all sorts.
The owner and his wife are now in sheltered accommodation and won't be
able to return. This is a last-ditch volunteer effort to stop all the
vast warehouse's contents being recycled and to make some money for
them to support them in their last years.

Folks;
I have a BA23 VAX of unknown provenance, which tonight I moved from the project backlog to the workbench. It comes up and passes selftest. But any key I press on the console terminal is repeated a couple dozen times (to the limit of the input line length?). This makes it impossible to interact with ODT.
Is this a normal sort of well-understood failure mode? In this session excerpt, the only thing I am sending is <BREAK> (giving me the normal chevron prompt), <ENTER> (giving me the repeated chevrons, sometimes with other characters in the pattern), ?, and h. I did not type any colons at the [XQA0] prompt, though I did try to backspace them. The behavior is the same if I remove all boards besides the KA655-B and 16 MB memory board.

I wondered if it was fair to list the DEC 23B00A2, etc that hold the ucode
as separate parts; they might have been a bunch of 256x4 PROMs, and the
separate part numbers were just for the different programming. (Whether
differently programmed PROMs count as 'different' parts for the purposes
of this table I leave aside.)
Looking at my M7232 card, though, I think they may be masked ROMs; the
only part number on them looks like a manufacturer applied one with the
DEC number.
Interestingly, about a third are MMI parts, and the rest are NS. I wonder
if neither manufacturer had enough capacity alone, or if DEC just wanted
multiple sourcing. (The parts appear to be basically the same, in terms of
speed, format, etc so it appears either could have provided any of them,
modulo the programme.)

Hi, I'm looking for some older HP 1000 A class parts and wanted to see
if anyone had them... below is what I need... If you have them, let me
know.
12103L? 4MB Memory Board
12103-66002 4MB Memory Board
12103-69102 4MB Memory Board
12016A? SCSI Interface Board
12016-69102 SCSI Interface Board
Thanks

This is what makes a PDP-11/35 or PDP-11/40 tick. It turns out to be
441 ICs. Impressive!

I thought I was the only one! Back when I first used a PAL, I
also photocopied the page from the databook, marked up
the connections I wanted, and then asked my coworkers
how to get that programmed into the device. It was pretty
annoying to learn I had to convert it to equations first. It
seemed like a pointless extra step when the software was
just going to turn around and turn the equations back into
the matrix wiring I had just marked up.

Does anyone have any experience working with modems that didn't include
internal / auto dialers?
They came up in a conversation in a newsgroup and I realized that I know
of them, but know virtually nothing about them.
I think they were separate devices, which probably means that they
likely had separate serial ports to talk to each of them. Did they
support some sort of pass through? Or did they really require two
serial ports on the host?

I pointed them to RFC 1436 in case they haven't been paying attention.
I eagerly await their next protocols, IPX and TCP/IP!
