Subject: 2. How to get this FAQ

This file is posted to the Usenet groups comp.sys.palmtops,
comp.answers, and news.answers monthly, near the middle (+/- 5 or so
days) of the month.  If this copy is much over a month old, a newer
version probably exists.  Since this document is crossposted to
comp.answers and news.answers, it gets archived at lots of different
ftp sites. Ask your sysop for info on your nearest news.answers
archive, or if there is no nearby news.answers archive, use anonymous
ftp and get



If you have no access to anonymous ftp, send an email message to
mail-server@rtfm.mit.edu, subject ignored, body containing

------------------------------

Subject: 4. Basics -- What are these HP Palmtops, anyway?

Q: What is the HP100LX?
A: Depending on your point of view, it's either an IBM PC-XT stuffed
into a very tiny case with some Personal Information Management (PIM)
software and Lotus 1-2-3 built into ROM, or it's a high-end electronic
organizer that also runs MS-DOS software.

Q: What is the HP200LX?
A: It's the successor to the 100LX.  It's essentially a 100LX with 
cosmetic changes and the addition of Pocket Quicken, LapLink Remote,
and some feature enhancements for the PIM applications in the ROM.

Q: What is the HP1000CX?
A: It is basically a 100LX/200LX, but without the PIM software in
ROM.  Its only built-in software is MS-DOS.  Hardware is essentially
identical to the 100LX/200LX.  It was originally only available in
lots of 50 or more, made to order by HP, but some places (Educalc, et
al) currently sell individual ones.  It's not targeted directly at
the consumer market.  HP seems to intend for third party
manufacturers to bundle it with add-on hardware/software on a PCMCIA
card for specialized applications.  Contact HP directly for more info.

Q: What's the difference between the 100LX and the 200LX?
A: Pocket Quicken from Intuit has been added to the 200LX.  This is a
limited version of the Quicken financial management software sold for
MS-DOS and Windows.  It does not use the same file format as Quicken
for DOS or Windows. but if you buy the 200LX connectivity kit, you
can share data with the full DOS or Windows version of Quicken. (Like
the 100LX, the 200LX can also run the full version of Quicken for DOS
outright.)

The DataComm application is faster in the 200LX. It can pretty much
keep up with a 9600 or 14.4 modem.  The painfully slow DataComm
application was a notorious deficiency in the 100LX, so this is a
welcome fix.

The case has changed color.  The keyboard layout has changed slightly,
in order to give Pocket Quicken its own dedicated key.  The labels on
the keycaps have a slightly different, italic, look to them.

The topcard (picture displayed when the machine is turned on, and the
system manager is running, but no apps are yet activated) looks
different.

There is an extra megabyte of ROM (3M in the 200LX, vs 2M in the
100LX).  This is how they managed to add the new built-in software
to the 200LX without deleting any of the old 100LX features.

There is a power-on password feature.

Some extra goodies have been added to the d:\bin drive (in ROM).
Hearts & Bones and Lair of the Squid are two games that are included.
A hexadecimal calculator is also included.

LapLink Remote has replaced the redirector for use with the
connectivity pack.

The appointment manager has a daily pop-up message reminding
users of "to do's" and appointments.

The on-line help has been improved.

The phonebook can present phone and address details in
"business-card" or the 100LX-style "form" format.

Q: What is the same between the 100LX and the 200LX?
A: Most things.  Hardware is virtually identical, including size,
batteries, AC adapter, serial port, PCMCIA port, display, keyboard
(except very minor changes to keyboard layout, and cosmetic changes
to the labels on the keycaps), processor, RAM, availability of 1MB
and 2MB versions, etc.  DOS compatibility is unchanged; both machines
use MS-DOS 5.0 and CGA.  Lotus is the same.  All the same PIM apps
are included, and they can share data between the 100LX and 200LX,
but the 200LX versions have a few enhancements here and there.

Most software written for the 100LX will run on the 200LX.  All
vanilla DOS software should run exactly the same.  Most
100LX-specific software will probably run the same.

Q: What's the difference between the HP-100/200LX and HP-95LX?
A: The short answer is that the HP-100/200LX is faster, has better
and more powerful software, much more MS-DOS compatibility (full CGA
compatiblity), fully standard serial port with hardware handshaking,
longer battery life, and has a PCMCIA Release 2.x slot.

Q: Where's the best place to buy a 100/200LX?  A RAM Card?
A: The answer changes too quickly to put into this FAQ.  Netiquette
suggestion: Read the newsgroup for a few days. If the question hasn't
been asked recently, call around to your local stores, call the
dealers on hpdealer.txt, and post a note listing the best deal you
found, asking if anyone can beat it.  In other words, do a little
homework yourself before asking the net for help.  Consider giving
your local dealer a chance to try and match or beat a mail-order
price.

List price of the 200LX-2MB is $699 (U.S.), $50 less than the
100LX-2MB list.  The 200LX-1MB lists at $549, the same as the
100LX-1MB.  Of course, actual selling prices vary, and they change
too quickly to report in this FAQ.

When pricing memory cards, be aware that some manufacturers package
disk compression software with their cards, and some of these may
advertise a 5MB card with compression software as a "10 MB" card.
(or "10 MB compressed", or "Up to 10MB", etc.)  Quoted disk
compression numbers tend to be optimistic, especially if you're
storing executables or compressed files.  Be sure you do an "apples
to apples" price comparison between different vendors.

Q: How can I upgrade my 100LX to a 200LX?
A:  You can't.  However, it's reported that Edu-Calc is offering a
$225 trade-in allowance for a 100LX, good toward a 200LX.  This is
presumably for a limited time only.

------------------------------

Subject: 5. 1MB vs. 2MB models

Q: Is the 2MB model worth the extra money over the 1MB Model? 
A: The only difference is the extra Megabyte of internal "disk"
storage on the C: drive.  It may be cheaper to buy the 1MB model and
invest the difference in a bigger PCMCIA flash or SRAM card.  But if
you want to keep the PCMCIA slot open for a PCMCIA modem or other
device, you're stuck with internal storage only, and the extra
megabyte may be	worth the money.

Q: Does the 2MB RAM HP-100/200LX have more system memory?
A: No, both models HP-100/200LX are MS-DOS machines which are
inherently limited to only 640KB of system RAM.  But an EMS (not XMS
or himem) driver has been written; see emm040e.lhz or emm100.exe
on eddie.

------------------------------

Subject: 6. Hardware and physical characteristics

Q: How big is a 100/200LX?
A: Approx 16cm x  8.5cm x 2.5cm (6.25" x 3.3" x 1") closed, or about
the size of a checkbook, only thicker.  It has a clamshell-style case.

Q: So tiny!  Can I touch-type on it?  Is the screen too small to read?
A: Touch typing is quite a trick.  The keys are much closer together
than normal adult human fingers.  But the keys have a positive click
feel.  Some people adapt quite well to them, others despise the 
100/200LX keyboard.

The screen is very sharp and contrasty, but your eyes might not be.
Try before you buy, especially if you have trouble reading fine print
in dim light.  The print is quite small in 25x80 mode, but you can
use special key combinations to zoom and pan around, displaying only
a portion of the screen, magnified, on the 100/200LX physical screen.
The screen is not backlighted, and is easiest to read in bright light.

Q: Where can I get a carrying case for a 100/200LX?
A: For a cheap padded case, look for one designed for a pocket 35mm
camera, game machine, personal stereo, or calculator.  For a fancy
executive-style leather case, see ads in the Palmtop Paper, Edu-Calc,
etc.

------------------------------

Subject: 7. DOS compatibility

Q: Will it run ? 
A: The 100/200LX will run just about anything that will run on an IBM
PC-XT with a CGA monitor.  To give you an idea of its compatibility,
here's a partial output listing from MSD.EXE, Microsoft's diagnostic
tool.  This was run on a 1MB 100LX.

Q: Can I run Quicken for DOS on it?
A: Yes, users have reported success with DOS-based Quicken through
version 8 (most recent Quicken version available as of this writing).
Recent versions may require more memory than is available under the
system manager, but it's easy enough to exit the system manager and
run Quicken directly from the DOS prompt.  The "disable filer" trick
may allow you to squeeze even the latest Quicken in under the system 
manager.

Some kind of extra storage (flash or SRAM card) will undoubtedly be
necessary for recent versions of Quicken, especially for the 1MB
100/200LX.

Of course, Pocket Quicken is built in to the 200LX, and it's
available separately from Intuit for the 100LX.  It's system-manager
compliant, but some users still may prefer the full feature set of
DOS Quicken.

Q: Can I run 4DOS on it?
A: Yes, but the advantages mostly occur outside the system manager.
For swapping, usage of the EMS driver emm100.exe is recommended.
Unfortunately, if you call DOS from the system manager, it will be
the hard-wired d:\dos\command.com.

Q: Can it do Windows?
A: Sorry, try an Omnibook or another larger laptop.  Windows 3.1
requires a 286 or better.  Windows 3.0 is barely possible, but the
100/200LX doesn't really have the speed, processor architecture,
display, or memory to make it a very practical Windows machine.
Forget Windows 95.

Q: Why don't Intersvr, LapLink, Procomm, etc. work?
A: They do work, but not under the system manager, unless you use the
trick described below.  The System Manager slows down the serial
port.  It can also interfere with console I/O. If you're having
trouble running something under the System Manager, try exiting
completely (Menu-Application-Terminate all) and run the program from
raw DOS.

If the program runs under raw DOS, you can probably get it to run
under the system manager by putting an inverted exclamation point
(keystroke Fn-Filer) into the comments field of the Application
Manager.  This effectively disables the System Manager and prevents
switching to another application while the current application is
running.

------------------------------

Subject: 8. Built-in Software

Q: What software is built into the 100/200LX ROM?
A: MS-DOS 5.0, Lotus 1-2-3 release 2.4, an appointment manager
(capable of waking the 100/200LX up and sounding an alarm or running
a program even when the machine is turned off), a calculator (similar
to HP19B, capable of algebraic or RPN), a text editor, a phone book,
a stopwatch/alarm clock, a world time database, a terminal emulator
(but the 100LX version is too slow to use above 1200 baud, you'll
want a different communications program for a fast modem), a general
purpose database, a note taker, a file manager, a keyboard macro
editor, and cc:Mail. Note that, although MS-DOS 5.0 is built into
ROM, not all of the external commands (e.g QBASIC.EXE, EDIT.COM,
ANSI.SYS) are included. These may be copied from a PC running MS-DOS
5.0  (Caution: copying parts of DOS is probably illegal and/or a
violation of your license agreement unless you buy a DOS license for
your 100/200LX).

The 200LX contains Pocket Quicken and LapLink Remote, in addition to
the above.

Q: Does anybody actually use cc:Mail on the 100/200LX?
A: Very few have posted to comp.sys.palmtops claiming to use it.
cc:Mail on the 100/200LX requires that you have access to a full
cc:Mail Post Office set up for dial-up access, and those don't seem
to be very common, at least among usenet denizens.

There is a program to allow you to use the cc:Mail software to
read/write Unix mail using uqwk(1) on the unix host.  Look for
qualx13.zip on eddie.mit.edu (last seen in the /pub/hp95lx/inbound
directory, but probably soon to be moved).  Free registration for
personal use.

Q: What is the system manager?
A: It's the core software under which all of the PIM applications
run. It allows multitasking (suspending one application to run
another), keyboard macros, data transfer via a clipboard, and other
nifty stuff. The alarm clock and appointment manager will only wake
up if the system manager is active.  Certain 3rd party applications
(*.EXM files) are "System Manager Compliant".  Applications which are
not system manager compliant can still be run, either by exiting the
system manager entirely, or by opening up a DOS shell under the
system manager.

Q: How can I transfer data to/from the database manager?
A: Read the manual on the smart clip feature, or use the gdbio
software (C source code included) available on eddie to import/export
in comma delimited format.

------------------------------

Subject: 9. Add-on software

Q: What's some good software?
A: The HP-100/200LX is an almost completely compatible MS-DOS machine.
Just about any MS-DOS software will work if it: fits in available
drive space, needs only what MS-DOS system RAM is available, needs
only CGA graphics, and runs in Intel x86 real mode.

Some HP-100LX specific software is at the URLs:



Q: What is 100Buddy?
A: It's a shareware program available on eddie which lets you do lots
of neat tricks, including make the filer automatically start an
application based on a file's extension (e.g. click a .wk1 file to
start 1-2-3), get a shifted value of a character by simply
double-clicking the character, get battery voltage displayed in a
status bar in the filer screen, reprogram the blue application keys,
add password protection to the 100LX (registered users only), display
the world-time map with nighttime areas shaded (also registered users
only), and lots of other shortcuts and tricks.

Q: Is there a 200Buddy?
A: Yes, it was released around the first of 1995.  It's available on
eddie.mit.edu in the /pub/hp95lx/NEW directory.  It will probably be
moved into the 100lx directory structure shortly, so you may have to
look around for it.  It is also available on the CompuServe HPHAND
forum.  Note that the filename is 100buddy.zip; the same version
works on both the 100LX and the 200LX.

Q: What is VR?
A: Vertical Reader, a shareware program available on eddie for
reading ASCII text files while holding the 100/200LX with the hinge
vertical, like a book.  VR has several attractive fonts available,
and allows searching for regular expressions.  This shareware may be
registered by merely sending a postcard to the author, or by donating
$10.00 to Project Gutenberg, an organization which makes
public-domain documents and literature freely available in ASCII text
form.

If you register VR via postcard, note that the author's address has
changed.  The correct postal address as of February '95 is:

   Gilles Kohl,
   Hagsfelder Allee 16
   D-76131 Karlsruhe
   GERMANY


Q: Can I use the 100/200LX as a remote control for my TV, VCR, stereo? 
A: The shareware program REMCOM, originally developed for the HP95LX,
works on the 100/200LX and turns it into a universal learning remote
control, using the infrared port.  RC is a similar program which is
also reported to work.  There may be other such programs developed
for the 95LX which work on the 100/200LX.  Unfortunately, the
100/200LX has a fairly weak IR transmitter (weaker than the 95LX), so
the range may be only a meter or two, less than the typical distance
from couch to TV.

Q: Can I use the 100/200LX as a phone dialer?
A: The HP95LX had a D/A converter that could drive the speaker and
produce touch tones fairly easily; sadly, this feature was dropped in
the 100/200LX.  That converter is instead used to monitor battery
charging.

However, there is a program, called ATDT, which uses some fancy
tricks to get touch tones out of a standard PC-AT.  It does work on
the 100/200LX, and it's available on eddie.mit.edu in the
hp95lx/unknown directory (ATDT01.ZIP).  It is not integrated with the
phone book application, it requires the video mode be set up
different from standard (see the readme), and, depending on the phone
you use it with, the 100/200LX speaker may not produce sufficient
volume to reliably dial.

There is also a program called TT available, with source code, on
eddie.mit.edu.  TT comes ready-to-use, but if you have a C compiler
and know how to use it, you can modify TT and integrate it into other
programs.  Like ATDT, TT suffers from the limitations of the volume
output from the 100/200LX speaker, and your success with it depends
on your patience, the sensitivity of your telephone's microphone, and
the placement of the 100/200LX speaker near the microphone.

Q: Is there an EMS driver?
A: Yes, EMM100.EE, available on eddie.  It uses a paging file on C:
and supports EMS 4.0 almost completely.  There is a 200LX version
in preparation; to avoid problems with Lotus 1-2-3 using EMS, copy
D:\BIN\200.COM to C:\100.COM and call 100 to start the system manager
as an intermediate solution.

------------------------------

Subject: 10. Programming the 100/200LX

Q: What programming languages are available?
A: Anything that'll run on a PC-XT, including various flavors of C,
C++, Pascal, Basic, etc.  QBASIC.EXE is not included, but will run if
it's copied from a MS-DOS 5.0 machine.

There are several ways to write "programs" with software in the
100/200LX ROM, depending on your definition of a program.  You have
the keyboard macro application, Lotus 1-2-3, the calculator's solver
application (finds roots of equations, among other things), DEBUG.EXE
(from DOS), and the DOS batch file interpreter.  The calculator's
solver application can be used with Lotus to "backsolve", that is,
adjust the value of one independent cell of a spreadsheet to produce
a desired result in another, calculated, cell.

Q: How can I get information on programming the internals of the HP?
A: The palmtop Developer's Guide is being distributed by Thaddeus
Computing (publishers of the Palmtop Paper).  Price is $79.00 US,
plus $5.00 shipping inside US, $12.00 shipping outside US.  It
contains full documentation on the internals of the HP Palmtops,
plus software for developing system-manager compliant applications.
You'll need to supply your own compiler and/or assembler (MSC 6.00AX
and/or MASM 5.1 are recommended).  Order from Thaddeus Computing, 
57 E. Broadway, Fairfield, IA 52556 (800) 809-5603, (515) 472-1875,
75300.2443@compuserve.com

For those who don't want to purchase the full developer's kit, there
is a library called PAL (Palmtop Application Library) which is a
collection of C language functions that provide DOS programs with the
look & feel of HP100/200LX built-in applications.  It provides
graphics functions, support for windows, menus, dialog boxes, etc.
It is free, and available on the HPHAND forum on CompuServe, as well
as ftp.monash.edu.au, eddie.mit.edu, and butler.sidewinder.com.

Many of the HP's interrupts are documented in the interrupt list,
maintained by Ralf Brown, available at
 and elsewhere.

Of course, if you only want to program the HP as a DOS machine,
without accessing any of the palmtop's unique features, there are
plenty of widely available books giving details on DOS programming.

If you need the file formats for the built-in applications, gdbio (on
eddie) has C source code which should provide a good starting point.

Subject: 11. Modems & Telecommunications

Q: What's a good modem?
A: Just about any pocket modem or PCMCIA modem.  A full-sized
external modem will work fine too, but of course it's not as
portable.  Specific features such as size, modulations and protocols
supported, cellular phone support, power drain, and others vary
considerably.

Q: Should I get a PCMCIA modem or an external one?
A: Advantages to PCMCIA -- Cleaner cable setup, uses same power
supply as HP100/200, smaller overall package.  Advantages to external
-- allows use of RAM card and modem simultaneously, doesn't drain
HP100/200 batteries.

While a pocket modem typically draws power from a battery or from an
AC power supply, a PCMCIA modem draws all power from the palmtop.
Most PCMCIA modems are designed to work on larger machines with
plenty of battery power so most modems also consume as much or more
power than the HP-100/200LX.  This drain can occur whether the modem
is in use or not, consequently battery life is much shorter, as
little as 15 minutes.  Use of an AC adapter is usually recommended.

Since there's only one PCMCIA slot, it can either hold a modem or a
SRAM/Flash card, but not both (but see next question).  So a PCMCIA
modem can only transfer data to and from the internal RAM drive of
the machine.

Q: How can I get a both a modem and flash card into one PCMCIA slot?
A: There are two companies which make combination modem/flash cards,
which combine a modem and a flash card into a single PCMCIA card. The
vendors are Smart Modular Technologies (510 623-1251)
, and EXP Computers (800 EXP-6922).  The cards are
specifically designed for the HP palmtop computers.  Both cards are
reviewed in the Jan/Feb 1995 Palmtop Paper.

Q: What cable do I use for an external modem?
A: The HP cable will work, but you'll have to use a gender
changer/null modem adapter.  See the description of the connectivity
pack elsewhere in this FAQ.  Or you can make your own cable.

Q: Why is my modem so slow?
A: The System Manager slows down the serial port.  The DataComm
application is even slower, at least on the 100LX.  Together they are
really slow.  The solution is to not use either, although using any
other communications software under the System Manager is better than
using DataComm. MS-Kermit (various version from 60KB to 300KB),
Procomm, Telix, and others are reported to work.  See the
minimal-software-list for details.

Interestingly enough, the built-in DataComm application seems to be
reasonably fast when doing file transfer, it's only when used
as a terminal that it becomes painfully slow.

The 200LX does not suffer from the slow screen update bug on the
built-in DataComm application.

Q: How can I read Usenet and mail offline with the 100/200LX?  
A: There's almost nothing special about the 100/200LX in this regard;
it's just like any other DOS PC.  Check out the newsgroup
alt.usenet.offline-reader.  Their FAQ may be found at

 

If you want to ask questions over there (AFTER reading their FAQ),
just tell them that your HP is an IBM PC-XT compatible running DOS
5.0 with CGA.

People have reported success using a UQWK/YARN combination to transfer
mail and news via SOUP.

The one area where the 100/200LX is unique is that it has cc:Mail in
ROM.  There is a program to allow you to use the cc:Mail software to
read/write Unix mail using uqwk(1) on the unix host.  Look for
qualx13.zip on eddie.mit.edu (last seen in the /pub/hp95lx/inbound
directory, but probably soon to be moved).  Free registration for
personal use.

Q: What's a good fax program?
A: There are several good fax programs available that will run on
MS-DOS with CGA.  Your modem may have come with one.  Users have
reported success with the following, but there are probably more.

1. SSFAXER: Shareware on eddie.mit.edu.  Must register in order to
   receive faxes
2. BGFAX: Available at 
    
3. There's a free demo package from TurboPower software that contains
   a small toolkit for sending and receiving faxes.  Can send faxes from
   PCX, TIF, TXT formats.  But fax viewer software only supports VGA, hence
   viewer won't run on palmtop.  This package is actually a demo of
   their Pascal/C++ communications toolkit.  Available at
    
4. ACEFAX contact info unknown.

Subject: 12. Connectivity to desktop computers and other devices

Q: How do I connect the 100/200LX to a desktop PC?
A: For the 100LX, HP sells the connectivity pack, (HP F1021A) which
comes with a serial cable, (HP F1015A) a package of various adapters
for different serial connections, (HP F1023A) and software for the
PC.  The PC software includes versions of the 100LX PIM software (but
no Lotus 1-2-3, sorry).  The filer applications let you transfer
files back and forth, and the redirector program lets you use one
machine's disk drive from the other machine (but it's slow).

A similar connectivity pack is available for the 200LX (F1021B,
w/English docs, F1021C with multilingual docs).  The 200LX
connectivity pack includes software to integrate Pocket Quicken with
Quicken for DOS or Windows, in addition to updated versions of the
software in the 100LX connectivity pack.

A "software-only" version of the 200LX connectivity pack is also
available, for those users who already have cables and such from
a 100LX.

Q: What if I don't want to buy the connectivity pack?
A: If you don't want to buy the connectivity pack, you may connect
the palmtop and desktop with a serial cable and use your choice of
DOS connectivity software.  The interlnk/intersvr programs that come
with DOS 6 work fine.  One way to start is to transfer intersvr.exe
to the palmtop using the built-in telecom application on the palmtop
and any terminal emulator on the desktop.  The Kermit file transfer
protocol works well enough.  Then install interlnk on the desktop
according to the documentation, and run intersvr on the palmtop.  Now
you can access the palmtop's drives from the desktop.

200LX users may take advantage of the built-in LapLink Remote
software in the HP's ROM.  A brief sketch of how to do this is:

1. Add the following line to your Palmtop's AUTOEXEC.BAT before
   sysmgr is started.
      CALL D:\BIN\LLRAS.BAT
   Then reboot your palmtop.

2. Copy the following files from D:\BIN on the 200LX to a directory 
   on the PC (use the built-in datacomm application and a terminal 
   emulator, or any other method you choose).
      LLRA.BAT
      LLRA1.EXE
      LLRA2.EXE
      LLRA3.EXE
      LLRA4.EXE
      TSI.INI

3. Edit the TSI.INI file on your PC as follows:
     In [general], change ComputerName= to something else (eg desktop)
     In [Redirector], change Enabled= to Yes.

4. Edit the LLRA.BAT file on your PC, changing all file paths from 
   D:\BIN to the PC directory you copied them to in step 2.

5. With the PC and palmtop connected via serial cable, enter the
   AppMgr on the palmtop and start the LapLink Remote Access program.

6. On the PC, change to the directory where you copied the LapLink
   files, and type "LLRA".  In a few seconds you should hear beeps
   from both the PC and palmtop indicating that a connection has
   been made.

7. On the PC, type "LLRA /M" to display the drive mapping.

8. To Unload LapLink from the PC, type "LLRA /U".

Q: Where can I get just the HP-100/200LX serial cable without the
Connectivity Kit?
A: EduCALC, etc.  HP sells it as part no. F1015A.  The same cable is
used for HP's calculators (it comes with an adapter to fit their
serial connector), so check the calculator section of a well-equipped
