For reasons too abstruse to explain in detail I'm on the lookout for
terminals that are, physically, really small - especially serial and
coax 3270, and possibly twinax 5250.
Yes you could do things with small laptops and PDAs with PCMCIA cards
and adapters and software - I know a guy who kept a Psion Organizer
configured especially for use as a terminal with SGI boxes. But that's
Not The Same, and NOT what I'm after; I want dedicated purpose-built
terminals; switch it on and It Works.
And both DEC and IBM made 'real' terminals in a 'small pizza box' form
factor, using a separate standard VGA monitor as a display; one could
use those with a small LCD screen and achieve a similar result, and I
might do just that - can anyone remember the model numbers of IBM 3270
and 5250 terminals that were built this way?
But really I'd prefer a compact all-in one solution; a one-piece
terminal. Any suggestions? I'm open to both LCDs and *small* CRTs.
Preferably colour!

And the Atari Portfolio runs a version of DR-DOS.
And the Poqet ran MS-DOS.
Both have serial ports available.
Both will run DOS software, including most of the undocumented calls, such
as TSRs.
Either can function as a terminal.

Subject: Oddball question: really small terminals
For reasons too abstruse to explain in detail I'm on the lookout for
terminals that are, physically, really small - especially serial and
coax 3270, and possibly twinax 5250.
5" might be a bit small even for me! The 9" version looks pretty close
to that kind of thing I have in mind except:
1. The 9" unit is just the display; the terminal logic itself is
another box, just as big.
2. It's a 4700 series system, which AFAIK uses its own strange
protocols; it's not 3270 or VT100 compatible or ANSI serial.
But on the right lines... thanks!
Small computers running DOS aren't what I had in mind, neither are
single line displays :-)
This is along the right lines, although it's a TCP/IP network device
without serial or 3270 ports for direct connection, and it doesn't
have a screen:
http://www.axel.com/uk/id_M75.html
The 3488 was the IBM 'terminal in a pizza box I was thinking of:
http://store.flagshiptech.com/ibm-infowindow-ii-3488-v-twinax-terminal-base…
But's it's Twinax; can anyone remember the number of the coax 3270 equivalent??
My *ideal* device would be something like a 10" or 12" LCD panel with
terminal logic built-in: power connector, 3270 or serial port, and a
PS/2 or USB keyboard port. A terminal you can hang on the wall. Cable
it up, hang it on the wall, away you go... if I can find something
along those lines I'll take a dozen :)
Thanks

I have a couple of AX3000 M75. I'm pretty sure you can connect
directly to a host through the RJ45 serial ports. It's been a while
since I've used them and I forget the details of the setup /
configuration screens.
I also have a similar ESPRIT 350C
http://www.sourceforterminals.com/newpdf/350C.pdf
These were reasonably cheap when I picked them up on eBay a while ago.

Small computers running DOS aren't what I had in
mind,
Can you explain what your objection is?
In what qualitative or quantitative way is a DOS computer running terminal
software fundamentally different from a terminal that did not also have
general purpose capabilities? A DOS machine can be setup to run the
program on startup - in the case of HP95, Poqet, and portfolio, the
memory cards gave you close to the same speed to boot and run the
software as a dedicated machine.
neither are single line displays :-)
OK.
BUT, it would have helped if you were to say what you are doing and what
you WANT, instead of just rejecting systems that are not what you want.
We'd waste less of your time.
"physically really small" means different things to different people.
It could mean that a pocket computer is the upper limit (I have used a
CCTV viewfinder as a monitor), or it could mean that you want ADM3A
(iMac prototype?) V IBM 3270 terminals.
What does "really small" mean to YOU?

OK, that's much closer to a description!
Howzbout: Connectbot running on an Android tablet?
Do you want the keyboard to remain attached? (unfold a Sony Vaio, or any
small laptop)
Or only use the keyboard for setup and maintenance/reconfiguration?
(back to tablet)
What are your keyboard requirements? IBM "M", Palm thumbpad, "virtual
keyboard" with touchscreen?
Your desire for COLOR throws a serious crimp in many/most dedicated
terminals, and points more towards "thin client" or dedicating a general
purpose machine.

"physically really small" means different
things to different people. It
45 years ago, a "mini-computer" was considered to be "really small".
So
small that they gave it a special name to refer to how tiny it was.
Sony tried to call their Vaio "ultra-portable",
which was rather laughable when held up next to an OQO.

First thing that comes to mind are the Informer terminals. They had them
in small CRT versions and the more rare orange plasma display with the
folding lid. The plasma one that I have seen was a 3270 emulation,
complete with the PF keys. I know it had serial...not sure about coax. I
believe I have seen the CRT ones with coax options. Both monochrome
displays.

Not The Same, and NOT what I'm after; I want dedicated purpose-built
terminals; switch it on and It Works.
Three things that I use for small async RS232 terminals....
1) (The one I use all the time). HP palmtops. I actually prefer the 95LX as the 40
column display is easier to read in poor light when working on a rack. But the
100LX and 200LX are good too. Yes, it is a computer, but it has a built-in serial
port (just need a cable) and terminal software in ROM. The good points are that
it will capture the downloaded data and you can kermit it to another machine if
you so wish. The standard cable is wired to plug directly into a PC and is thus a
DCE, but I got a second cable, cut off the moulded D connector and wired it to
a DB25 plug as a DTE.
2) One of my RS232 testers has a terminal mode on a 32*4 LCD. Just a dumb
terminal, though, but it will do odd baud rates and 5-bit ITA2 (incorrectly
called Baudot) which can be useful
3) You will not find one, but Trend Data Systems did a version of the Opal
telex terminal that was a very good VT100 clone (even down to the
setup mode). A clamshell design with a fold-down LCD and a full-size keyboard.
Runs off 12V (I am missing the original PSU for mine) and the power connector
(A variant of the UK telephone plug) is almost as hard to find as the machine.

Having read you want Color I would see if you can get a NeoWare thin client with TN3270
support.
My only gripe is that I have not found a way to get one of my Nokia 3270 keyboards to
fully work with them.

Actually, there is an OS -- MS-DOS -- and it's in ROM too. Along with a text
editor, address book thingy, HP financial calculator (19B-II a-like, it does have a
4 level stack RPN mode) and Lotus 1-2-3. I've never needed to use an application
other than the ones in ROM on these machines.
The terminal emulator has a VT100 mode (which seems to work reasonably
well). And plain text, Xmodem and kermit file transfers. I've used it to download
a file from one machine, then carry the palmtop to a different room and upload
said file to a different machine if it would be impractical to run a cable.
It is certainly a machine worth considering even if it doesn't meet all your
requirements at the moment...

Just stick one to the back of a small LCD screen and I'm in business.
But on closer inspection the site shows "out of stock". I'll email;
maybe they'll do another batch. Or does anyone know someone who has
stock?
And I'm still left with the need for something for 3270...
Useful thread though; all kinds of interesting things coming out of

One issue with the VT525 is that you might have to experiment with a
few different LCD monitors to find one that produces an acceptable
display, especially if you want to use 132 column mode.
The last time I tried this with the LCD monitors I happened to have on
hand a ViewSonic VP2000s, a Samsung 931B, and a Dell 1704FPTT all
produced unacceptable results while an older ViewSonic VP150 did
reasonably well.

I had a thing that was apparently used in France and maybe
Canada for telephone directory lookup and similar uses. I
believe it was called a Minitel. It had a TINY CRT screen,
maybe 5 x 7". It used a standard 40-pin microprocessor and
other standard parts. I junked mine because it would
randomly reset every minute or so, and I didn't really have
a use for it. I think mine was smaller than the one in the

No, mine did NOT have a pull-out or fold-down kbd, it was

No, it WAS a Minitel. The Wikipedia picture gives nothing for scale, but there
is a picture of one on a Google pictures collection that shows it on a desk with
a regular keyboard and LCD screen, and you can see how small the thing
really was.

scale from that pic.
A pull-out keyboard in the base? I have one too. Would be perfect if
it worked, and I had half a dozen of them!
No, mine did NOT have a pull-out or fold-down kbd, it was all one
piece, Jon
Something like the iXO handheld
terminal?

The French Minitel, and British Prestel, were videotex systems.
Canada's national effort of the late-70s/early-80s at a videotex project was Telidon.
Telidon resulted in protocol standards (which led to NAPLPS), and some hardware was
produced, but it never saw major deployment as the Prestel and Minitel systems did.
I'm not aware of any Minitel presence in Canada.
Perhaps some terminals made their way here for use as compact terminals in some
application or some such.
For reasons too abstruse to explain in detail
I'm on the lookout for
terminals that are, physically, really small - especially serial and
coax 3270, and possibly twinax 5250.
I had a thing that was apparently used in France and maybe Canada for telephone
directory lookup and similar uses. I believe it was called a Minitel. It had a TINY CRT screen, maybe 5 x 7". It used
a standard 40-pin microprocessor and other standard parts. I junked mine because it would
randomly reset every minute or so, and I didn't really have a use for it. I think
mine was smaller than the one in the Wikipedia article, but it did look similar to that.
There are some on eBay, but they are all from France and Belgium. Interface was pure
serial RS-232.
