Emu48 - A freeware HP38/48/49 Emulator for Windows 9x, NT and 2000
|
||
|
||
|
||
|
||
****************
|
||
* INSTALLATION *
|
||
****************
|
||
|
||
Emu48 is distributed in 1 archive:
|
||
- Emu48-1_20.zip All files and sources
|
||
|
||
To install Emu48, just unzip Emu48-1_20.zip into an empty directory. When you
|
||
first run Emu48, it will detect the directory in which you installed it, and
|
||
will write its configuration to a file named Emu48.ini in your Windows
|
||
directory.
|
||
|
||
You can also update your current version with the Unofficial Service Packs:
|
||
- E48BP2x.ZIP New EXE-File
|
||
- E48SP2x.ZIP Sources of the Service Pack
|
||
|
||
Replace the original EXE file please.
|
||
|
||
|
||
********************
|
||
* OPERATING SYSTEM *
|
||
********************
|
||
|
||
This version of Emu48 should work with all Intel Win32 platforms. You may
|
||
recompile the sources to run Emu48 with Windows NT on a DEC Alpha.
|
||
|
||
|
||
************************
|
||
* YOU NEED A ROM IMAGE *
|
||
************************
|
||
|
||
Emu48 needs an image of the ROM of YOUR calculator to be able to run. Since the
|
||
ROM is copyrighted by HP, I won't give you mine, and you should not give yours
|
||
or make it freely available. To use the ROM software of a calculator, you must
|
||
be the owner of this calculator.
|
||
|
||
- HP38:
|
||
To upload the ROM of your HP38G, you will need a special aplet called "ROM
|
||
UPLOAD", available at http://www.epita.fr/~avenar_j/hp. Once you've uploaded the
|
||
ROM, you have to convert it using the Convert utility.
|
||
|
||
To do that, start a Command Prompt while running Windows, and type:
|
||
Convert <rom-file> ROM.38G
|
||
|
||
Where <rom-file> is the path to your ROM image. This will create a file named
|
||
ROM.38G. This tool will also check its validity.
|
||
|
||
- HP48:
|
||
If you have already used another HP48 emulator, you can convert the ROM using
|
||
the Convert utility.
|
||
|
||
To do that, start a Command Prompt while running Windows, and type:
|
||
Convert <rom-file> ROM.48G
|
||
or Convert <rom-file> ROM.48S
|
||
|
||
Where <rom-file> is the path to your old ROM image. This will create a file
|
||
named ROM.48G or ROM.48S, depending on the version you own. This tool should be
|
||
able to read any style of ROM image, and will also check its validity. Note that
|
||
if you run it with only one parameter, no file will be written, but it will
|
||
still check the validity of the ROM.
|
||
|
||
If you have never used an HP48 emulator, and don't have a ROM dump, you can
|
||
either use Jean-Yves Avenard's ROMUPL.BIN or the ROMDump Wizard V1.x, which will
|
||
almost automatically get the ROM from your HP48. Don't use the ROMDump Wizard
|
||
versions V0.x any more please! After the download you may have to convert your
|
||
dump with the CONVERT utility into the Emu48 format.
|
||
|
||
You can find the latest version of the ROM dump programs on:
|
||
ROMUPL.BIN http://www.epita.fr/~avenar_j/hp/calcen.html
|
||
ROMDump Wizard http://privat.swol.de/ChristophGiesselink/index.htm
|
||
|
||
Once you have your ROM dump(s), SAVE THEM TO A FLOPPY DISK! It will save you a
|
||
lot of trouble if you were lose them.
|
||
|
||
- HP49:
|
||
There's no ROM download program available so far. But you can find a HP49G ROM
|
||
for emulators in the YorkeM emulator package or in the HP49G SDK on
|
||
http://www.hpcalc.org in the HP49 section.
|
||
|
||
|
||
****************
|
||
* HOW TO START *
|
||
****************
|
||
|
||
When Emu48 is installed and you have put the ROM image(s) in the Emu48
|
||
directory, you can start Emu48. You'll see a "Choose Your KML Script" box.
|
||
|
||
KML Scripts in fact define the visual aspect of Emu48, the behavior of the
|
||
buttons, of the keyboard, ... It's a GREAT way to customize your copy of Emu48.
|
||
|
||
Check that the path in the "Emu48 Directory" text area is correct. Modify it if
|
||
the directory in which you installed Emu48 is not the directory displayed. Click
|
||
the refresh button ("V") after modifying it to update the list box.
|
||
|
||
Choose a KML script in the list box. If you have put a G/GX ROM dump in Emu48's
|
||
directory, choose a script for G/GX. If you have put a S/SX ROM dump in Emu48's
|
||
directory, choose a script for S/SX.
|
||
|
||
Several scripts are included in the common archive:
|
||
* Emu48's Default Faceplate for HP48G/GX
|
||
* Emu48's Default Faceplate for HP48S/SX
|
||
These two are simple scripts, good for 800x600 display resolution.
|
||
* Casey's Gx with Toolbar and Touch Screen
|
||
* Casey's Sx with Toolbar and Touch Screen
|
||
These script uses many advanced features, and is a good demonstration of
|
||
the power of Emu48's scripting language KML. Try it, it is really great!
|
||
* Floating buttons
|
||
This one looks really great.
|
||
* Small but realistic HP48 Gx
|
||
This one has been designed for small resolutions such as 640x480.
|
||
Note: some things in this script have to be fixed.
|
||
|
||
If you want other great scripts, visit Casey's Emu48 homepage:
|
||
http://www.gulftel.com/~pattersc/emu48/
|
||
|
||
And if you are interested in writing new scripts, get the KML 2.0 documentation
|
||
from Christoph's page at http://privat.swol.de/ChristophGiesselink/emu48.htm
|
||
|
||
Once you have selected a script, press OK to start the emulator. While it's
|
||
running, you can use the View/Change KML Script... command to change the visual
|
||
aspect of Emu48.
|
||
|
||
|
||
***************
|
||
* KML SCRIPTS *
|
||
***************
|
||
|
||
In some cases you have to fix Color 0 in your KML script file, because the
|
||
colors red and blue has been swapped in the "Lcd" section (bugfix in a previous
|
||
version). Don't use TRUELCD.KMI for emulating display contrast in your scripts.
|
||
It's not fully correct. The hardware contrast values are in the area from 0 to
|
||
31. But the ROMs bounds them to useful values. The HP48 S(X) ROM use only
|
||
display contrast values between 3 and 19 and the HP48 G(X) ROM values between 9
|
||
and 24.
|
||
|
||
|
||
****************
|
||
* COMMAND LINE *
|
||
****************
|
||
|
||
The command line syntax is "Emu48 [E48file [Port2file]]". The first parameter
|
||
sets the filename for the emulation data, the second parameter the Port2 file.
|
||
You're not able to set a Port 2 file without setting the emulation data file.
|
||
The arguments are optional.
|
||
|
||
|
||
*******************
|
||
* LOAD/SAVE FILES *
|
||
*******************
|
||
|
||
There are two ways to transfer files from or to the emulator. The one way is to
|
||
use the serial port to transfer the data directly from your HP to the emulator.
|
||
The second way is to load data, saved on your PC, into the stack of the
|
||
emulator. You can do this by using the Edit/Load Object... command or with the
|
||
file Drag and Drop feature. But there's one important restriction, the data must
|
||
a HP binary file (begin with HPHP48- or HPHP49-, this depends on your emulated
|
||
calculator)! If not, the data is load as string. The Edit/Save Object... command
|
||
will save the data in stack level 1 on the PC (always binary mode). Be sure,
|
||
when you use the second way for data transfer, that no program is running on the
|
||
emulator. The second way doesn't work on a HP38, because he has no stack. So you
|
||
can load aplets only from the serial port.
|
||
|
||
|
||
*****************
|
||
* DRAG AND DROP *
|
||
*****************
|
||
|
||
Dropping HP objects over the emulator window will load program files (like the
|
||
command "Load object...") on the stack. Be sure that the emulator isn't busy
|
||
before doing this.
|
||
|
||
|
||
*******************
|
||
* SHARED RAM CARD *
|
||
*******************
|
||
|
||
You can add a SHARED (I'll explain later) ram card of up to 4MB to a HP48. By
|
||
default, no such card will be created when you start Emu48. The MkShared.exe
|
||
utility will allow you to create it.
|
||
|
||
The syntax is:
|
||
MkShared <filename> <size_in_kilobytes>
|
||
|
||
For example, you can create a 4MB RAM card name SHARED.BIN (in Emu48's
|
||
directory) with the following command:
|
||
|
||
MkShared SHARED.BIN 4096
|
||
|
||
Valid sizes are 32, 128, 256, 512, 1024, 2048 and 4096 KB. If you use RAM cards
|
||
greater than 128 KB in a HP48SX, you can only see the first 128 KB of the card.
|
||
|
||
When you have created this file, run Emu48, and use the Close menu item to close
|
||
the calculator state. Now select File/Settings. In the "Port 2" text area, type
|
||
the name of the file you created (if you don't include a path, it will be
|
||
searched for in Emu48's directory).
|
||
|
||
You can also tick the check box "Port 2 Is Shared". When the box is cleared,
|
||
only the first instance of Emu48 will allow you to use the RAM card in Port 2.
|
||
When this box is ticked, the first instance of Emu48 will give you both read and
|
||
write access to this RAM card. If then you start Emu48 again, the RAM card in
|
||
Port 2 will be write-protected. Thus you can transfer files very easily between
|
||
two calculators. This RAM card is used by both S/SX and G/GX types.
|
||
|
||
|
||
***********************
|
||
* FLASH ROM EMULATION *
|
||
***********************
|
||
|
||
The HP49G save the operation system a reprogramable memory, a so called flash
|
||
memory. The flash memory is divided into two parts, into the Operating System
|
||
and into a User Data area. The User Data area is viewed as Port 2 in the HP49G.
|
||
Emu48 saves the Port 2 data in the ROM file (normally ROM.E49). As default
|
||
setting the ROM file is writeable in the first instance of Emu48. When you open
|
||
another instance of a HP49G emulation the Port 2 area is READ ONLY, that mean
|
||
all changes in Port 2 are lost when you exit this instance. If you don't want to
|
||
save data in Port 2 and want to protect the operating systems from overwriting,
|
||
you're able protect the ROM file. To do this, close all Emu48 instances and set
|
||
the variable 'Writeable' defined in the Emu48.ini file, section [ROM] to zero.
|
||
|
||
|
||
***********************
|
||
* COPY / PASTE STRING *
|
||
***********************
|
||
|
||
With the menu items "Copy String" and "Paste String" in the "Edit" menu you're
|
||
able to copy HP string objects from the stack to the PC clipboard and vice
|
||
versa.
|
||
|
||
|
||
**********
|
||
* BACKUP *
|
||
**********
|
||
|
||
Emu48 includes a backup feature (in the Edit menu). It save the complete state
|
||
of the calculator in the computer's memory. You might want to use it before
|
||
doing something risky, and if you don't want to save to the disk. It provides
|
||
some kind of Undo feature. It is also used by Emu48 when you want to save or
|
||
load a new document, to restore its old state if you cancel the operation or of
|
||
something goes wrong.
|
||
|
||
|
||
************
|
||
* KEYBOARD *
|
||
************
|
||
|
||
To enter a character to the emulator use the PC keyboard (key translation
|
||
depends on the used KML script) or the mouse. If you press the left mouse
|
||
button, the emulator key is pressed as long as you press the mouse button or
|
||
leaving the area of the emulator button. Sometimes you need to press more then
|
||
one key (contrast setting, warmstart, ...). To do this, press the right mouse
|
||
button. All "locked" buttons are released after enter a key with the left mouse
|
||
button.
|
||
|
||
|
||
*********
|
||
* CLOCK *
|
||
*********
|
||
|
||
The emulator time is synchronized with the PC time at startup of the emulator.
|
||
This may cause problems with other non original operating systems running on the
|
||
HP. On HP48 S(X) calculators the address area #00052-#00070, on all other
|
||
emulated calculators the address area #00058-#00076 in Port 0 are rewritten with
|
||
the actual time information.
|
||
|
||
|
||
*************
|
||
* EMU48.INI *
|
||
*************
|
||
|
||
The section [Timers] in the Emu48.ini file isn't used any more. The variable
|
||
values are replaced by useful constants. You may delete this section if you
|
||
want. Starting an old version of Emu48 (V1.07 and earlier) will add this section
|
||
again.
|
||
|
||
|
||
************************
|
||
* REAL SPEED EMULATION *
|
||
************************
|
||
|
||
As you recognized the speed of the emulated HP is much faster than an original
|
||
one. The reason is, the assembler commands are emulated faster than the original
|
||
CPU can execute them. On one side this is a big advantage (faster execution of
|
||
programs) on the other side this cause many trouble. In Emu48 only the timers
|
||
work with the original speed. In result all commands like User-RPL WAIT wait
|
||
more or less the correct time. But many programs like shells or editors use an
|
||
own key handler to realize an autorepeat implementation. Normally these programs
|
||
use the execution time of each assembler command for waiting. On Emu48 this time
|
||
is much shorter, so the time between each key read is shorter as well and you
|
||
get a very fast key repetition. The editor ED from the JAZZ package hasn't this
|
||
problem, because the key input is synchronized with one of the timers. To solve
|
||
this problem Emu48 generally slow down emulation if a key is pressed. To solve
|
||
some other speed depending problems you are able to slow down the whole
|
||
emulation speed. There are two variables 'SXCycles=82' and 'GXCycles=123'
|
||
defined in the Emu48.ini file, section [Emulator] which control the "real" speed
|
||
and key repetition slow down for each calculator type. Each numeric value is
|
||
representing the allowed CPU cycles in a 16384Hz time frame. Because the used
|
||
cycle statements (from SASM.DOC) in Emu48 doesn't correspond to the real values
|
||
of the CPU, the saved values are estimated by comparing the execution time of a
|
||
program to the real calculator. Increasing the value fitting to your ROM will
|
||
make the "real speed" HP faster and vice versa. No warranty to the functionality
|
||
of Emu48 when you go below the default values.
|
||
|
||
|
||
*************************
|
||
* SERIAL PORT EMULATION *
|
||
*************************
|
||
|
||
The serial ports are emulated as well now. You may choose the same serial port
|
||
for wire and IR. Remember that the IR port only work with 2400 Baud. If you want
|
||
to change the serial port settings, but they are disabled, close the serial port
|
||
with the command CLOSEIO or power cycle the HP first.
|
||
|
||
Now it's possible to make transfers between the real calculator and Emu48. If
|
||
you have problems with the connection please try the following. There's a simple
|
||
way to check if your serial port is used by another program. First disable the
|
||
serial settings in both combo boxes and very important close the settings
|
||
dialog. Reopen the settings dialog and choose the COM port in the wire combo box
|
||
to the port the HP is connected with. When you open this combo box you only see
|
||
valid (unused) serial ports. Don't use the IR combo box, it only works with 2400
|
||
Baud. The next important thing are the serial settings of the real calculator
|
||
and Emu48, they must be equal. If this doesn't work then mostly there's a
|
||
hardware or a resource problem of the serial port. Check this with connecting
|
||
the HP with a transfer program you like on the same serial port.
|
||
|
||
|
||
****************
|
||
* DISASSEMBLER *
|
||
****************
|
||
|
||
With the internal disassembler you're able to disassemble the Saturn chip
|
||
address area. With the default Map setting the disassembler always see the
|
||
mapped memory address. If for example you configured the RAM at #00000 you will
|
||
see the RAM and not the ROM at this address. With the other module settings you
|
||
specify a special module for disassembly. Each module use a linear address mode,
|
||
beginning at address #00000 and will not overlapped by other modules. So, for
|
||
example, you can access the second port of a HP48 RAM card greater than 128KB at
|
||
address #40000 (128 * 1024 * 2). The "Copy Data" button copies the selected
|
||
disassembler lines to the PC clipboard.
|
||
|
||
|
||
**************
|
||
* DDE SERVER *
|
||
**************
|
||
|
||
I implemented a DDE server in Emu48 to transmit data from and to the HP stack
|
||
with DDE. You have the same restrictions like with the commands "Load object..."
|
||
and "Save Object...", that a running program may corrupt memory. Take care to
|
||
transmit data only after the acknowledge of the last DDE transaction.
|
||
|
||
Technical data:
|
||
|
||
Servername: Emu48
|
||
Topicname: Stack
|
||
Item: Dummy (ignored, must be a nonzero string)
|
||
Clipboardformat: "CF_HPOBJ" (user defined)
|
||
|
||
The DDE commands CONNECT, POKE and REQUEST are supported.
|
||
|
||
The structure of the clipboard format "CF_HPOBJ":
|
||
|
||
+--------+------------------------------------+
|
||
| 4 Byte | HP object |
|
||
+--------+------------------------------------+
|
||
\ \
|
||
\ +--- normal HP object
|
||
+----------- length of object (LSB first)
