Hi all!
Need to get rid of some things here that I am never going to use, maybe
someone else will:
M7705
M7706
M7906
M7907
M7908
Quad boards, I think they came from an RK06/07. Maybe the boards from an
RK611? Regardless, I don't need them, they are either priceless or
worthless. Make me an offer or I'll just let them go.
SGI Hi-IMpact board. Not sure why I have this but here it is.
Either pick up in MD or send me a shipping label.

Question: I'm starting to work on the concept of installing POS 3.2 on
my Pro380 and rather than burning a lot of floppies I'd rather just use
my Gotek with FlashFloppy.
First problem is this: The images are in lzh format, and when
uncompressed are TD0 format. Which I think is teledisk, is there a way
to convert those to the raw format used by Flashfloppy?
Ultimate goal is to get Pro/Decnet running, hook the 380 up to the
Ethernet here with my DECNA to the 11/73 running DEQNA, then try
sysgenning a version of RSX11M+ for the Pro that does not suck. Not sure
if anyone has tried this, or where they ran into roadblocks.
Thanks!

If anyone knows of a Sharp PC-5000 that might be available.
I've been looking for one for a while.
Might be more in the Japanese or European vintage market?
Prefer working, I've been curious about the MS DOS 2.0 ROM that it has.

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
