I've had a fondness for the Radio Shack TRS-80 PT-210 portable printing
terminal for a long time. Unfortunately, I've been unable to find an
RS-232 interface module for it. A couple years ago I found a hardcopy of
the service manual and used it to enter schematics and lay out a board for
it. I scanned it and that's the one that's circulating on the web. The
schematics and foil patterns in the service manual seem to be slightly
wrong, so I've been on the lookout for one on eBay. I found one and won
it just now and will use it to verify my design. I should have blank
boards ready for sale in a month or two.
If the other bidder is here, please email me with a screenshot showing
that you bid. I'll send you a blank board free of charge when I get
boards made.

Hello,
maybe you have also a dump for a 4000-100A ?
I have a motherboard which seems to have problems to Bcache or Pcache, and
another one which I took as replacement, which has a very old version.
I wonder if there's a way to dump the firmware in some way from the
non-working one, then update the other...
Of course I would avoid to desolder and resolder the flash Roms...

I'm looking for a small quantity of 10.5" half-inch reel tape seal
belts. These are the things that almost everybody with a large
collection of tapes used to hang their half-inch tapes in racks made for
the purpose.
At one time, like tape write rings, these things were as common as
cockroaches. Countless millions manufactured.
I can't seem to find anyone who is sitting on a pile of these. Not even
eBay. Mind you, I don't want the tapes themselves, just the belts. My
issue is that I'm getting sent tapes without cases or belts more
frequently. I suspect that in many situations, the belts have just been
discarded, as they break and become brittle with age.
I can remember discarding the hard plastic cases when refitting tapes
for the auto-thread drives. We'd fill up dumpsters with the things.
If someone is sitting a pile of the old cases, those would do in a pinch.
Any ideas or leads welcome.
Thanks,
Chuck

Note: I am only bringing along pre-sold PETs due to space constraints.
If you're interested in any of the above items, or any item in my VWOCW,
I'll give you a 10% off VCF special if you are prepared to pick up at the

I am wondering if anyone relatively near Southeast Iowa might have a
working 170kB 5.25" IEEE drive I can borrow for a few weeks.
I know it's a long shot, and you'd think I'd have one sitting here, but
all my boat anchor PET drives in my stack are 8050 units.
I am hoping to add some functionality to ZoomFloppy to support these
drives. I've tried approximating the 4040 with an MSD drive using the
IEEE connection, with no success.
While I am happy to buy a unit for a reasonable price, and I'll check
online for items for sale, that would most likely involve shipping, and
the PET drives are ill-suited to ship (financially, and for the health
of the unit)
It's not a show stopper, as VCF-MW is coming up soon, and I no doubt can
borrow a unit from someone then or maybe even fix the code that weekend
with a loaner unit.? Still, if I can create some success before hand, so
much the better.

When I posted the Sun keyboards, I did not realize that
1) The checkout would not work correctly for TX residents, and
2) The search box was not working.
My apologies for all those who tried to buy a keyboard, and could not.
Please try again?
