I have heard of people using an HP LX palmtop (the 100LX/200LX have a fuller
serial port implementation than does the 95LX) as a terminal for the type of
tasks you mention. The 200LX runs MS-DOS 5.0 on an i80186, so you should be
able to get a number of terminal emulation programs that will work on it.

Subject: Modern replica/implementation of a dumb terminal?
I was musing about the state of VT100s and other dumb terminals and
had a few ideas zing by...
<snip>
I have used my Palm Pilot as a portable terminal for reconfiguring
Cisco routers (VT100 app and a travel cable and the appropriate
RS-232 dongles). My boss at the time flipped when he saw me do it
(everybody else dragged a laptop into the server room). There are
just times when I'd like a laptop-sized-or-smaller ANSI terminal.
I can forego double-high/double-wide chars, inverse video and the
like for simplicity's sake (hardly ever used them in an app except
at the South Pole), but it should be complex enough to run a
screen editor (vi or emacs) and/or basic curses apps (Rogue/Larn/NetHack
and the like).
One place I thought BIOS replacement might be handy was in a sub-486
laptop.... just pull it out, plug it in and *voila*, it's a dumb
terminal weighing a few lbs. Yes, it's possible to drop an OS on
a floppy and add Kermit (I've already done that with a dual-720K-
floppy Zenith 8088 portabie). I'm thinking of a dedicated "instant-
on" experience.
I also have some "Net Stations" with a 5"x5" 486 motherboard stuffed
under a PC keyboard (with 4 30-pin SIMM sockets, IDE, serial, video,
and NE2000 network built-in). They don't run off batteries, but
neither do they have an intergral screen.
I've also tried to think of ways to adapt a Palm Pilot with a permanent
keyboard, but I'm not sure there's a way to do it with only one serial
port (terminals typically have at least two, even if one is dedicated
to servicing the keyboard and somewhat "invisible" to normal operation.
The final angle I've worked on is to recycle the main board in a
VT220 (being somewhat physically small), but I don't have schematics
and I don't know what signals go over the ribbon cable to the PSU/
Analog board under the CRT.
So has anyone else wrestled with how to cobble up a portable VT-100?
Anyone get any further?

If I had any HP Palmtops sitting in a drawer, I probably would have
started there. I know that the 95LX was popular years ago as a
portable packet terminal. Never had one, though. Wouldn't turn one
down if I saw it in a thrift.
I'm thinking more towards commodity laptops because they are much
more common. The LX palmtops certainly qualify for an out-of-the-box
device that's easy to add a terminal emulator to.
Thanks for the idea, but it's not quite what I'm working towards.

One of the guys I used to work with had a lovely little ARM based Psion
organizer that he used as a dumb terminal, but that's going to be in the
same category as the palmtops above.
If you're looking for something more like a commodity laptop, how about
just using a commodity laptop? They are, afterall, common as dirt.
If you're looking for something that's a non-classic computer, I think
the QuickPAD Pro is sort of nifty: http://www.victor-alvarado.com/qppro/

8086-based laptops with full 80x24 screens can be found in thrift stores
sometimes, and for cheap.
The ACCRC gets in tons of these. They would make great portable
terminals.
I still prefer my Psion though (2 AA batteries ;)

Even the Series 3 machines were amazing in terms of what had been packed
into the ROM: no Linux AFAIK, but with the SIBO platform, there is
multitasking available as well as a windows server and an IP stack (from
the PsiMail product). These are just examples, see the Psionics files
for more information.

runs on 3c /
3mx). I bought it together with my first 3a and was a happy user of
both.
Since then, the need for Telnetting into a host came up, and the trouble
is that Yellow's emulator is not capable of using the IP stack, but only
supports the serial interface.
So, I rolled my own VT320 emulator (I call it "V-Tel"), which has been
tested with VMS, True64, and Linux, and which supports the serial
interface directly as well as through PsiMail's TCP/IP stack. Editors
like vi or TPU do work, MONITOR SYSTEM on VMS is lacking the graphics
character set yet, but all control sequences are interpreted properly.
Perhaps I find the time to add double-width/double-height characters and
the semi-graphics font during Christmas holidays.
It may be a bit late to put V-Tel up as shareware, and it may be a bit
too early for the Series 3 to be discussed here, but if somebody is
still looking for a portable terminal, this solution works very well for me.

The Series 3 was awesome as well. I remember agonizing over the decision
between the Series 3 and two other organizers (one was the Sharp Zaurus,
the other may have been the HP OmniGo). I spent at least a couple hours
in Office Depot (major US office supply chain) playing with each one. In
the end, the Psion won because of it's GUI, 16-bit sound, and the fact
that it had it's own scripting language (OPL) making it easily and
immediately hackable.
I don't use the stylus a whole lot with my Series 5 anyway (my finger
works just as well) but it doesn't scratch the surface when I do.

I can't remember what serial applications I used my 3a for, but I have the
3link serial dongle so I must have used it for something. The Series 5 is
great because all you need is the cable (no dongle necessary). I had it
hooked up to my wireless modem (when it was still around, RIP) and coupled

terminal.

The Series 3 is definitely a classic in my book. It's already been
relegated to the collection (though it still sits in my office).
I wrote a program that would produce the "Red Box" tones to fool US
payphones into giving you free calls. It worked wonderfully. Sometimes
people would look at me strangely as I held my palmtop up to the receiver
of the phone. I'm sure they thought something nefarious was afoot. Ah,
the good old days.

New subject: Psion PDAs (was Re: Modern replica/implementation of a dumb terminal?)
Sellam,
you're talking in the past? - I am still using my Psion 3mx every day,
from typical PDA functions (contacts, agenda etc.)
through several
spreadsheet applications and a technical reference information base
up
to my shopping list (you should see the other visitors stare in the
supermarket! ;-) and games.
What OPL can do becomes obvious with some applications, your "Red Box
Emulator" is another example. V-Tel is also written in OPL. If I only
had the time to complete the setup program for configuration of my
private phone system...
Too bad that the infrared interface (3c, 3mx) was built too early to
conform to all relevant IRDC standards, but if I can locate some
information from the Psion SDK, there might be a solution...
As for the RS232 interface, the "soap on rope" cable used with the 3/3a
was changed into something that looks like a simple cable for the later
models (3c/3mx), I think it might be the same type as for the Series 5,
with a small flat connector at the PDA end instead of the 3-by-2
Berg-style plug.
And the display: yes, I know the pen is designed not to harm the
display, but I cannot help feeling like it might scratch, though -
absolutely personal opinion, of course. I tried a Series 5, but compared
to the Series 3, it didn't do enough to justify the switch: not even the
Opera browser could do what I was looking for, so I gave up and kept the
3mx.

Huh? What is V-Tel? Sounds *very* interesting. The "3a Box" program was
cool. It also did the Blue Box and Green Box tones (though niether work
anymore...it was more for novelty). You chose which tones you wanted
from a menu, and then it went to a subroutine for that
box. Red and
Green box tones were chosen from a menu. Blue Box tones were dialed
in
and then you hit "Dial" to send them out. I could walk through airports
chiming out MF tones. It made heads turn (I wouldn't do that today* ;)
Sadly, I believe the source is now lost for good. The harddrive that had
the backup files for that Psion has long since crashed and the batteries

New subject: Psion PDAs (was Re: Modern replica/implementation of a dumb terminal?)
Sellam,
yes, it is truly a matter of personal preferences:
I forwarded my Series 5 to my brother, who is happy with it, while I
happily continue to use the 3mx.
The infrared port of my 3mx does not work with my Nokia 6210, so I have
to carry around both serial cables and a null modem. Well, actually a
"null terminal" adapter (two male connectors) because both cables are
designed to connect to a PC (= to a DTE). This adaptor was much easier
to build than to find in a shop.
Going infrared, the Psion "sees" the cell phone in the proximity, and
with a small OPL program (OPL again!), you can prove that it can contact
the device and retrieve a description string, but you cannot access the
modem in the 6210. This is why I assume an incompatibility on a somewhat
higher layer of the IRDC protocol stack.
I seem to remember having seen programs for the 3 and 5 to allow the
exchange of data between these machines. Apparently, these programs
simply implement higher protocol levels themselves.
Right. Also built-in with 3c and 3mx. The 3 and 3a had a proprietary
(IIRC, 1.5Mb/s, full duplex) link between the Psion and the dongle. This
is why the same 6-pin connector could also be used for a parallel
printer interface.
Opera was not the original Web browser from Psion, but you could
download and install an EPOC version of Opera from their Web site.
Unfortunately, both browsers refused "https:", so I still have to boot
the PC for home banking. No "mobile banking" yet ;-)
you're
talking in the past? - I am still using my Psion 3mx every day,
For me I am ;) I don't doubt that you still find your Psion 3 useful. If
I didn't have my Series 5 I would still be using my 3a. Huh? What is V-Tel? Sounds *very* interesting. The
"3a Box" program was
I mentioned V-Tel in one of my earlier postings on cctech, and promptly
got a request for it off-list. It is a combined VT320 emulator and
Telnet utility, so you can use the 3a/c/mx for dialling into a TCP/IP
network and establish sessions to all kinds of hosts, with the ability
to use screen-oriented applications: editors, monitoring tools, games,
... ;-)
Before I started to write V-Tel, I looked for an existing application,
but found only a very elementary Telnet program (from Simon Wood; in the
comment lines, it said it was there only to prove that it is possible)
and a number of VT emulators, but none of them was able to connect
through the TCP/IP stack: they all used the serial interface
exclusively. Then I dug out an original VT320 (for comparison) and a
couple of manuals, downloaded RFC854...
Sadly, I believe the source is now lost for good. The
harddrive that had
the backup files for that Psion has long since crashed and the batteries
(main and backup) on my 3a went dead and took the program with it :(
A SSD (solid state disk) might have helped. I have two of the 4MB
devices in the A and B slots of my 3mx, but currently only need one of
them to store data. So, with my internal RAM (2MB) and a total of 10MB,
I am excellently equipped: for comparison, a spreadsheet including two
different graphical representations and a listing of daily stock rates
for three different papers over the course of a year takes about 50kB on
the 3mx. This includes the formulas to calculate values for sample
accounts (one account per paper) for each day.

That's the wonderful thing about Psion software. It is so devoid of

with a Microscoff dominated world.

I definitely need SSH if/when cheap wide-area wireless access (i.e.
Ricochet [RIP]) returns to the Silicon Valley. I no longer have telnet
ports open on my server due to little punks who go around vandalizing
servers because they are stupid and lame.

200LX with a docking port for a Nokia 2110).
The 200LX runs MS-DOS 5.0 on an
i80186, so you should be able to get a number of terminal emulation
programs that will work on it.
I though the 200LX used an 8086, more specifically
an Intel HORNET embedded
CPU?
BTW, the 700LX has a built in dumb-terminal program. Press the "&..."
button, then select "Data Comm" from the menu. It works. Just.
Just throwing my tuppence into the well...
Later.
