I am looking for some advice and recommendations on how to best go about
accomplishing the following:
I have recently come into possession of an actual physical terminal that can
be connected to a device via a standard RS232 (serial) port, so far so good.
I have a number of devices that can be connected to for maintenance (e.g. FW
updates, configuration, etc.) via a serial port. Currently I have been using
an old laptop with a terminal program (Procomm Plus) whenever I want to
connected to one of these devices. This involves crawling around connecting
the serial cable, doing what needs to be done, crawling back disconnecting,
rinse and repeat.
I can connect the physical terminal to one device at a time and have a
permanent connection to that one device, great for one device but not so
useful.
So I was thinking if it would be possible to do this over the LAN.
I know about console servers where I could connect multiple serial devices
to the server and then access each device over LAN via a telnet client on a
modern system using an IP:port schema. This works great except I don't get
to play with my shiny, new to me, authentic experience terminal device.
So I am wondering if there is a box that provides a telnet CLIENT to a
serial port device? I.E. a box smart enough that handles the telnet client,
LAN functions, and terminal emulations internally and then provides a text
based interface through a serial port that is compatible with my physical
terminal? That way my physical terminal would be connected to the RS232/LAN
bridge all the time and I could connected to not only the serial ports
connected to the console server but other telnet accessible services as all
the heavy lifting would be done on the bridge. I am ideally looking for a
ready to go, low power device, I can hide away as opposed to setting up a PC
of my own running some *nix flavor that I know can do this but is way over
kill. Oh yeah and if it is super cheap even better. Thanks!

Over the years I have been collecting BBS related memorabilia such as Night Owl shareware CDs, Boardwatch magazine, BBS magazine, books, manuals, original disks, etc. Does anyone have any BBS memorabilia they might be willing to sell to me? I’m particularly interested in PCBoard box/disks/manuals. I know the software can be downloaded from the Internet.. I’m interested in the original box set. I’m also interested in CRS Online pamphlets, receipts, catalogues, etc.
Has anyone ever seen promotional videos showing Prodigy, Compuserv, Delphi, GENie, AOL? I've collected disks, but the systems are long gone so archived video is all we have to remember them by. When I was young, I remember seeing disks and pamphlets for these services in the box when upgrading modems. They had serious brand recognition. By the time the Internet was becoming available to the public, I remember being more interested in getting a Compuserv account lol. After getting our first Internet account in 1994, I was confused because I didn’t know where the “file areas”, “message areas” and “chat” were after being so used to BBS menus. Eventually I learned about FTP, USENET, and IRC. We even had a “yellow pages” paper book where you could look up topic specific FTP, USENET, and Gopher sites.
Hi
The Tektronix 4970 does something similar to an IBM 3174 or 3708.
It hooks up terminals to an IBM mainframe, in this case Tektronix
graphics terminals, see [1], p.36ff.
Is anybody here in possession of the software that runs on it?

All,
Per the LAN-attached serial thread, here's another cheap Lantronix device:
https://www.ebay.com/itm/123577635191
This is a LRS-2, which is basically a two-port LRS-1, one of their older models of serial bridges. The LRS-2 is nice not only for the two ports, but because it also has AUI and thinnet.
No PSU, but it's a typical 12V 1A center positive supply.
Thanks,
Jonathan
Hello list,
does anybody of you know colour codes or the mixture to obtain the grey paint that DEC used for their early H960 cabinet side panels as well as for their later cabinet from the 80s and 90s like the H9A10 or H9A15?
Some of my cabinets have scratches and I would like to cosmetically fix this.
I thought I remember some discussions about DEC paint some years ago but I couldn't find anything helpful in my archives except for discussions about colours for DEC's classic front panels.
Any pointers are very much appreciated.
Thanks,
Pierre

Hi,
What is the "correct" name for the style (technology?) of circuit board
layout images where the top is blue, the bottom is red and overlaps are
purple? Also, any silkscreen is black. I thought someone once told me that
there was an automated tool (maybe in KiCad?) that would produce Gerbers
from that type of image. Does anyone know of such a utility?
Thanks,
Bill S.

What about one of these? https://www.amazon.com/dp/B07DWLS7DP
$11.38, and provides four ports. If that's not enough, you could do a
bi-level multiplex arrangement; 5 of these ($56.90) would provide 16 ports.
Zero power requirements, no software configuration. If it were me, I might
consider buying a two-pole rotary switch with enough positions and solder
one up, but for less than 12 bucks, it's hard to beat this...

I've just listed my complete HP-3000 system on eBay here. This is an
HP-3000 917LX system with:
Disks: (2) 2GB drive (possibly RAID, but I'm not sure)
Tape: (2) DAT (built-in and external)
16-port terminal concentrator
12-port Ethernet hub
Terminals (2) HP 700/96 + one 700/92 that probably doesn't work
Line-printer 300 LPM with stand, ribbons, and paper
Dot-matrix printers (2) with ribbons
All cables
MPE/iX, ASK/ManMan, QUERY, TurboIMAGE
FORTRAN
Documentation (50+ pounds, including all service and upgrade records)
It all works perfectly (as of two days ago). There's a possibility that I
might deliver it if you're near Portland OR or the San Francisco Bay area,
or off the I-5 in between; otherwise it's local pickup only (in either
location). It's listed for $2600 buy-it-now, or a starting bid of $2000,
but if you're really interested email with an offer and we'll see what can
be worked out...
