All,
I went to find a page about P&T Surplus to link to a friend who'd never been there, and this was today's top result:
https://www.dailyfreeman.com/2023/02/19/pt-surplus-in-kingston-struggles-as…
Apparently Mr. Smythe is having hard times with his business. For those in or near the Hudson Valley, this place is definitely worth checking out! They have a ton of industrial surplus, including a lot of IBM castoffs.
Pretty good shop for potential vintage computer stuff. Last time I was there (early February 2023) there was a box of neon lamp IBM front panels off what I'd guess was tabulating equipment. I always find good stuff in their board scrap, though the edge connectors are sometimes sheared off. There seem to always be earlier IBM Thinkpads there, Pentium 3 and earlier are common finds.
They also have lots of mechanical hardware, metals raw material, 80/20 extrusion for dirt cheap, etc.
Thanks,
Jonathan
Hello,
Some Sun 1/4" tapes with NeWS has turned up in the SF Bay area.
However, the the tape drive available has bad rubber baby buggy bumpers.
Is there anyone around there who can provide new bumpers, or has a
working 1/4" tape drive and is willing to read the tapes?
Best regards,
Lars Brinkhoff
I have the 3 volume set of the RT PC Tech Ref and it needs a new home. I’d prefer it winds up with someone that has a RT PC if possible. It’s in pristine condition.
Please email off list to tpisek at pobox dot com.

Todd Pisek
P.S. It’s fairly heavy, USPS media rate would be about $14.
Working on my second pdp11/73 here and trying to get Ethernet working
with a DEQNA instead of a Delqa. I'm using a DELQA card to AUI
connector, the board passes diagnostics without the loopback, but when I
try to bring it up I get:
Event type 5.14, Send failed
Occurred 17-FEB-2023 22:15:05 on node 1.20 (TALOS)
Line QNA-0
Failure reason = Collision detect check failed
Is the connector for the DELQA different from the DEQNA? My other system
has a DELQA with a DEQNA connector and it seems to work fine. I could
put another DELQA in, but I want to see if these DEQNAs work.
Or do I need to enable SQE on the AUI adapter?
Thanks!

Fellow cyber-antiquarians:
I have been fussing around with a TK70 for some hours now. It goes ready
when powered up without a cartridge, takes up the leader fine when a
cartridge put in and the flat, but then dithers forwards and backwards,
eventually flashing all its lights. The only way to remove the tape is
manually.
Somebody posted that the most common problem is optical sensors, stating
that there are four. I have only found two, and cleaning them got me to
the point of it coming ready, whereas it would not before.
Is there anybody on here that knows of a service manual? I see that
this was considered an FRU, so maybe depot repair people had a magic bible.
Once I have this fixed there is a TK50 to start on. I hate to give up!
I have a box full of cartridges to read!
cheers,
Nigel

Hi all,
I know there are a few PDP enthusiasts here so I figured this was worth
an ask!
I'm looking for any software, manuals, photos of hardware - anything
really - that relates to the Jerrold Communications / General Instrument
analog cable TV headend equipment.
Many of their headend "addressable controllers" were built around DEC
hardware -- the AH series units used a PDP-11, the Terminal Configurator
ran on a PC, the ACC-4000 ran on a DEC Prioris server running SCO UNIX.
Things I'm looking for especially --
- The software from the ACC-4000 Addressable Controller (Prioris
based), AI-0/AI-O or AH-4/AH-4E (PDP-11/73 based) controllers, or
Terminal Configurator (PC based).
- Backup tapes from a running system (may be TK50, or DAT/DDS)
- Terminal Configurator, Message Editor (ME-1000) or "OSD Edit" software
- Any documentation
- Photos, or other details of the I/O cards (either the PC one -
which may have been called ANIC - or the SCX11, SCX11E, SCX11M or SRT11
cards used in the PDP systems).
I'm trying to build an analog cable TV headend from scratch, as a bit of
a preservation and "to see if I can" project.
So far I've managed to modulate a couple of channels and get a cable box
to tune to them, but my two boxes have different frequency maps, and I
need some way of sending an "Input Frequency Map" or channel name table
to them.
I'm hoping that someone might have inherited a bunch of backup tapes,
hardware or media from a cable TV company who was migrating to digital....
Thanks,

Going through my stuff I found a Matrox QRGB 6/64-4 card which seems to
be a 512x512x16 color video array for Q bus systems.
Did any software ever support this thing, and does anyone want to trade
it for a bean of some sort?
Thanks!

Folks,
During lockdown I was having some fun redrawing old DEC manual covers
with Inkscape, specifically terminal and printer manuals from the late
1970s. I've attached a montage of four that I printed out so I could
stick it on the wall. I'm aware I may be the only person, even here,
who finds them attractively simple and coloured in such a definably
1970s way.
Some of these designs were used on several manuals, but I'd like to
know if you know of any other designs that follow this pattern that I
could add to the collection? The VT102 User Guide has different
colours, so it looks out of place. A copy of the LA34 User Guide is
winging its way to me as we speak.
For an infinite number of bonus points, does anyone have any clue who
might have designed these?
Paul
