Creating ROM image files of an HP-41 module
Posted by Juergen Keller on 9 Aug 2011, 4:55 p.m.
This is the procedure I use to dump a HP-41 module to .rom files (which then can be used, e.g, to burn a Clonix). Note that there are many other ways to do it ...
- HP-41 with capability to save a 4k page to a mass storage device, e.g.:
- HP-41CL with CCD/OSX (SAVEROM)
- HP-41CY (WRTPG)
- HP-41 with CCD OS/X provided by a Clonix module
- HP-41 with HEPAX (WRTROM) provided by a NoVRAM etc.
- HP 82160A HP-IL interface
- Windows PC (drivers required by PIL-Box need to be installed)
- PIL-Box device
- ILPer program
- HPDir program
- lif2rom program
- Insert the module to dump (and any other modules needed by your setup, e.g. Clonix) into the HP-41.
- Connect the PIL-Box to the PC, and the HP-41 to the PIL-Box.
- Dump all pages of the module to a LIF file
- Run ILPer (select mass storage LIF file, appropriate port and baud rate) and start the PIL-Box interface.
- Turn on the HP-41.
- Enter a file name for the page into the ALPHA register.
- Enter the page number (8-15) into the X register.
- Execute the SAVEROM function (or WRTPG, WRTROM, ...).
- Repeat steps 3 to 5 for all pages of the module.
- Stop the PIL-Box and quit ILPer.
- Extract all pages of the module from the LIF file and convert them to ROM files
- Open a command prompt.
- Run Hpdir -extract <file> <page>, where <file> is the name of the LIF file (as specified in step 3.1) and <page> is the name of the page (as entered in step 3.3).
- Run lif2rom <page>.#e070 <name>.rom.
- Repeat steps 2 to 3 for all pages of the module.
Any comments are welcome.
