The Complete Package! (for the hp 39gs,
hp 40gs & hp 39g+) |
|
This package contains:
| the Communications software for the hp 39gs, hp 40s and hp 39g+. |
| the ADK39 editing software. |
This is a single package containing everything that you need to
have in order to use the cable that should have been in your package
when you bought your calculator. The Comms software lets you send and receive programs, notes and aplets
to/from the the PC. The ADK39 lets you edit them once they are on the PC.
Just download the package into an empty directory, open it, and
read the instructions here on how to install onto your PC in the README.TXT file
it contains.
Note:
-
The files are contained in a compressed ZIP
file. You will need to extract them before you can use them. The
easiest way to do this is to right click on the ZIP file and use
the Windows extraction wizard.
-
Sometimes when you install the comms
software the driver that lets it link your HP to the computer
does not install correctly. A 'driver' is a file that
lets the computer talk to hardware such as printers and
calculators. The symptom of this is either
|
that the program will run but will keep telling you
that it can't detect the calculator, OR
|
|
that when you run it and
plug in the calculator (switched on) Windows says that it is
detecting
new hardware and pops up the wizard to ask for the location of the driver.
|
If this happens the easiest way to cure
it is to use the 'New Hardware' wizard to tell it to look for the drivers in a particular
location. On the pop up Windows "Detect" dialog, tell it
not to look on the web but instead to look for the driver in a
specific location (tick the box). Tell it then to look in C:\Program Files\Hewlett-Packard\USBDriver.
It will tell you that the driver is not one that's registered
with Microsoft (oh, dear we shall die of shame!). Tell it to
install anyway
and it should then work correctly. If not then the most likely
cause is low batteries. You need really fresh batteries to link
to the computer.

ADK39 - Aplet Development Kit for
the HP39G/HP40G |
|
If you already have the communications software installed and
working then you may only need the ADK39.
The ADK39 allows you to:
| edit notes which you have saved to a PC |
| create programs and aplets on a PC |
It is absolutely essential for anyone wishing to develop aplets
or programs for these calculators, or for people wishing to
create large notes without having to type them on the
calculator.
Originally the only version developed by HP was for the HP38G but
a talented user called Yohan in France produced a version which
will allow you to create and edit HP39G and HP40G files.

HP38/39/40G/39g+/39gs Emulator |
|
Emu48 is a great program written by
Sebastien Carlier and Christoph Giesselink, and enhanced by
Jean-Yves Avenard, Eric Rechlin and myself, amongst other
people. It is free software and you can use it and
distribute it freely subject to certain conditions (see
README.DOC for details on this). The package you can
download from this page will emulate the HP38G, HP39G and HP40G.
It will also emulate the 39g+ and 39gs but only in the sense of
showing the faceplate. The internals are still those of an HP39G
and so does not contain the Finance, Triangle Solver or Linear
Solver aplets. A detailed manual (README.DOC) is included with the
package.
The package you will download from this page is complete and
ready to run as soon as you unzip it into its own directory and
you can distribute it freely but you must not sell it or
include it in any package that is sold for profit.
The reason for the lack of emulation of later models is as
follows:
Prior to the end of 2000, there was a copyright problem that
meant that you had to upload a copy of your own calculator's ROM
in order to use the emulator, which wasn't simple. To their
credit HP decided in 2000 that they would release the ROM image
of the 39G & 40G as long as it was not part of a package being sold for
profit. Unfortunately they changed their mind again
when the 39g+ was released, which is why the package doesn't
contain any ROMs for later models: I have them myself but I'm
unfortunately not allowed to release
them. However.... |
An
hp 39gs Emulator: You can now also obtain an
emulator from the HP site called "Vapple". I won't
give a link because it seems to change quite regularly! Instead,
go to the HP site
and do a search under "emulator". After following a couple of
links you'll hopefully find yourself at a page where you have to supply your name and
details of what classes you teach. It also asks for a curriculum
but I just put a note that I was Australian and they could have
it if they emailed. They didn't. This emulator covers the 39g+,
39gs and 40gs (plus 48gII,49g+,50g) and has some really nice
faceplates, including some that (like the 38G shown in the image
above) have the keyboard sideways.
There are two big drawbacks of the Vapple emulator:
- The package comes with an installation serial
number and checks with HP via the internet to see how many times
you've installed the emulator. This means that your computer
MUST have an internet connection the the first time you run It.
After that it doesn't matter. The serial number also stops working after 3 installations.
However.... if you contact me and give me proof that
you're a teacher then I can get you more installation codes.
Email me via my Contact page.
- The emulator won't load aplets. This is likely to change
soon: I've seen a more recent version that will load aplets
but it hasn't been released yet (as of Dec '07). If that
changes then I'll post the info here and on my main page.
For this reason, I use BOTH emulators in my classroom. For day
to day operations I use the Vapple because it is significantly
better looking and has the same aplets as the students. If I
need to demonstrate the use of one of my aplets then I use the
EMU48 emulator.
Note...
| An upgraded version of the central program to the emulator
is available from the web site of the author Christoph
Geisslink . This upgrade incorporates a number of
small improvements which are mainly of interest to those
using the program to emulate the HP48 and HP49 rather than
the HP38/39/40G family. If you want to upgrade then
just download it from his site. I haven't bothered
incorporating it into my download. |
| Students who have some visual impairment will be pleased
to know that this emulator includes two versions which may
help. Firstly a version of the HP38G which runs
with a screen which is four times normal size. The
second is a version of the HP39G with the same large screen,
plus huge keys and very
high contrast colours. The
logical mapping of the keyboard to the keys on the PC also
means that you can almost use it with your eyes closed. :-) |
| One of the big weaknesses of the Vapple emulator is that you can't load aplets onto it.
IF YOU HAVE A 39G then you can use it to upload aplets directly to the
emulator via the serial cable. If you have one of the
later models then you can't do this (they use the USB port)
but I've include a lot of my
aplets in the package you get here in a zip
file ready to be loaded into the emulator. You have to
expand the zip file into a folder before you can use them
though. |
|
For Mac users, the good news is that there is now a Mac
version of the emulator! Download the emulator itself (click
here) and then some of the files needed to emulate the HP39G (click
here). These files can also be found on the page by
Pierre Tardy
and Da Woon Jong
along with extra information and the source code. You should
also download the PC version of the emulator and transfer
all the files shown right into the folder you put
the rest of your Mac files into. These files contain a number of additional emulations
of the 38G, 39G, 40G and 39g+ on top of those that come with
the Mac package. They also contain saved
copies of most of my aplets that can be loaded into the
emulator (the zip files). Expand those into separate folders
inside your emulator folder if you want to use them. |
| For Unix users: You have first get your own version
of the emulator program for Unix, written by Ivan Cibrario Bertolotti,
called the saturn program which already covers the 39G &
40G. There are also adaptions to include the 38G by Khanh-Dang.
In addition, you also need the ROM files from my emulator
package because the saturn program doesn't include
them. Download my package and just extract the files
called rom.38g & rom.39g. If you want the aplet
files that I created then you'll also need to extract 38gAplets.zip
& 39GAplets.zip and create folders to contain their
contents. You may also want to extract the Readme.doc file
because much of the information will still be relevant.
You need these 2 files for the basic saturn program:

The Complete Package! (HP39G) |
|
This package contains:
| The HPGComm
This program is only for the HP39G & 40G which use the serial
port not the USB of later models. |
| The ADK39 |
| A Help file explaining how to use both of these. |
This is a single package containing everything that you need to
have if you own an old 39G or 40G. You'll need to purchase your
own cable, however, since one did not come standard with the
machines (see Sampson cables on my links page). The HPGComm
program lets you send and receive programs, notes and aplets
to/from the the PC. The ADK39 lets you edit them on the PC and the
Help file explains it all.
Just download the package into an empty directory, unzip it, and
read the instructions on how to install them onto your PC in the
README.TXT file.

HP-Paint Version 1.3
|
|
This is an aplet, adapted by the author
from an existing HP49 program, which enhances the HP's ability to handle
graphics. Firstly it allows you to work on all of the screen (131*64
pixels) and not just the 125*64 offered by the built-in Sketch editor. Secondly,
HP-Paint allows you to zoom in on a part of the grob. This really comes
in handy when you want to put fine detail in your images. Thirdly, in
HP-Paint you can shade parts of the grob with different patterns: Lines \\,
Lines \\(2), Lines //, Lines //(2), black and even with a custom pattern.
Finally, you can make the interior of the boxes you draw either
black or white, rather than the empty interiors in Sketch. In
addition to this it offers everything the built-in sketch editor offers.
Click on either icon to download it. The zip file contains versions
for both the HP38G and the HP39/40G.
Authors:
HP-Poska (conversion to 38/39/40G). Originally by François Darras,
Erwan Ancel, and Laurent Mallet.

m48+ - The HP Emulator for the iPhone
|
|
If you'd like a
version of the EMU48 emulator (see above for the PC version) that
will run as an App on your iPhone then check
this site out. I've
not used it myself so I've no idea how good or bad it is. I don't
own an iPhone so I can't test it.

KeyDebounce Aplet (HP39G & 40G
only) |
|
This
utility aplet is ONLY for the HP39G & HP40G. Do not use it with
later models! The internal keybounce time is set in order to prevent a key
registering twice. When you press a key you may only hold
it down for a fraction of a second but to the calculator this is
a LONG time and if there were no delay set then it might, for
example, read what you meant to be a '3' as a '33'.
However, on the HP39G & 40G, the default factory setting of 166.6ms delay is a little
high and sometimes causes a REAL press of '33' to only register
as a single '3' when you actually meant 33! Changing the
delay value to a setting of around 75ms will reduce the chance
of this happening.
When you first run the aplet it will display the current
delay time. For an HP39G this is 166.6 milliseconds.
You can alter this to any value from 0 to 400. Based on
our experience a good value to try is 75ms.
Once the value is set it will remain until a memory reset
(ON+SK3 or ON+SK1+SK6) is performed on the calculator. Deleting
the aplet will not affect it and, since the aplet is only 1.3Kb
in size, it may be worth retaining.
This is not a complete cure for the problem but it does seem
to help.

HPGComm - Communications Software (HP38G, HP39G & HP40G
only) |
|
This program is called HPGComm and will run with either an HP38G, HP39G or HP40G.
It allows you to upload or download aplets, programs etc from
the HP38/39/40G to a PC. This program will run on Windows
'95, '98, NT, Me and XP.
Note: You must
already have the cable to be able to use this software. The
cable did not come standard with the calculator. See Sampson
Cables on my Links page.
This software was written by James Bergamin in Switzerland,
with helpful criticism from me. It is not sold by nor supported
by Hewlett Packard, although you can download it from their web
site.
Note: Although HPGComm has a help file it is
rudimentary and I wrote a better one that included instructions
on how to install and use HPGComm and the ADK for both the HP38G
and the HP39/40G. It is unfortunately not linked into the
HPGComm program so you have to run it separately, but I have
managed to link it into the installation routine for the new
HP39G ADK (see above). If you install the 39G ADK then a
shortcut will be created in the program group created for the
ADK on the Windows Start menu which also points to my help file.
Warning!
A bug was found in the initial release of HPGComm. If you
downloaded it before July 2nd, 2001 then you need to download
and install a replacement version in which the bug is fixed.

HP38G ==> HP39G File
Converter |
|
This utility converts any files that were saved from or created
for an HP38G into files that are compatible with all later
models. It it works
fine with notes, lists, matrices and ordinary aplets.
However it is not always 100% successful with aplets which have
attached programs because the positions of the keys have changed
from the 38G to the later models and so any programs which reference
specific keys may need to be revised by hand after conversion. |
