CARDCOPY - A HP48 Port1 Import/Export Tool for Emu48
05/23/00 (c) by Christoph Gießelink, cgiess@swol.de
************
* CARDCOPY *
************
Emu48, when emulating a HP48, save the user, the port1 memory and other
information in one file (*.E48). But sometimes it's useful to import or to
export port1 data. CARDCOPY now allows you to import/export a 128KB card file
into/from the port1 memory of an Emu48 state file. The program can handle
HP48SX/GX state and 128KB card files (file size 256KB) as source or destination.
On all other file types you'll get an error. It's recommended to switch off the
emulated HP48 before importing port1 data into a state file. So you're sure that
the HP48 wasn't busy and, when you switch on the emulated calculator, the
changed card will be detected.
Remember: Don't import data when port1 is merged! This will corrupt memory.
Second, when you import data, all files that are saved in port1 are purged.
The syntax is: CARDCOPY <Sourcefile> <Destinationfile>
Some examples:
- SX.E48 , an Emu48 state file for a HP48SX
- GX.E48 , an Emu48 state file for a HP48GX
- RPLTOOLS.BIN , a 128KB port2 file
If you want to
- export the port1 content of SX.E48 to RPLTOOLS.BIN then type
CARDCOPY SX.E48 RPLTOOLS.BIN
- import the RPLTOOLS.BIN as port1 into GX.E48 then type
CARDCOPY RPLTOOLS.BIN GX.E48
- export the port1 content of SX.E48 to GX.48 then type
CARDCOPY SX.E48 GX.E48

* REAL SPEED EMULATION *
************************
As you recognized the speed of the emulated HP48 is much faster than an original
HP48. 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.

The next important thing are the serial settings of the HP48 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 HP48 with a transfer
program you like on the same serial port.
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

* DISASSEMBLER *
****************
With the internal disassembler you're able to disassemble the HP48 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 will begin at address #00000 and
will not overlapped by other modules. For Port2 I use a linear address mode,
that means that the second port of a RAM card greater than 128KB is at address
#40000 (128 * 1024 * 2) and so on. The "Copy Data" button copies the selected

Known bugs and restrictions of Emu48 V1.15
Known bugs and restrictions of Emu48 V1.20
------------------------------------------
- the following I/O bits aren't emulated (incomplete)
@ -30,15 +30,26 @@ Known bugs and restrictions of Emu48 V1.15
-> all programs that run on a real calculator will run as well,
programs with incorrect DA19 / BEN handling may run on the
emulator but will crash on a real calculator
- no MP interrupt on card control circuit or timer restart
- no beeper support with OUT command -> all programs that aren't
use the "=makebeep" subroutine, like alarm wake up, have no sound
- beeper emulation, ATTN key doesn't work,
Windows 9x: plays only default sound event or standard system beep
- no infrared printer support
- problem with timer2 (8192Hz) emulation in Windows 2000, timer2
values may skip, so an emulated delay loop may take very very long
- memory window of debugger view some addresses in I/O register area
with invalid data
- Shell OS: clock isn't synchronized with real time
- HP49G: flash ROM is treated as ROM (no writing to flash memory)
-> writing to port 2:FLASH will crash the emulation!
- HP49G: the flash memory is emulated now with some restrictions
- first implementation, at the moment the flash memory is more a
simulation than an emulation
- no flash programming times, the flash state machine returns
immediately the ready signal
- only one write buffer, second not needed because of prior reason
- not fully tested, especially the status byte may sometimes
return incorrect values (error bits)
- quitting the emulator while programming the flash isn't allowed,
because the content of flash state machine isn't saved so far

The HP49G save the operation system a reprogramable memory, a so called flash

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,

* REAL SPEED EMULATION *
************************
As you recognized the speed of the emulated HP48 is much faster than an original
HP48. 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.

special module for disassembly. Each module will begin at address #00000 and
will not overlapped by other modules. For Port2 I use a linear address mode,
