The Museum of HP Calculators The Museum of HP Calculators
Some of the programs in this library require ROM modules to be present. When the ROM module is in place, you'll see a user-friendly name like "COSH" but when the ROM module is removed, the same instruction will be displayed like XROM rn,fn where rn is the ID number of the ROM (0-31) and fn is the ID number of the function (0-63) within that ROM. Because Leo's decompiler doesn't have a list of all the ROM and Function IDs, it can't translate the XROM commands in the files back to the user-friendly names.
The list below will tell you which ROM or ROMs use which IDs. Some IDs are used by more than one module and some modules use more than one ID but it usually easy to guess which ROM is needed based on the program. Once the module is installed, the XROM statements in the downloaded program will be displayed in the user-friendly way.
The easiest way to enter programs with XROMs is to download one of the code files or to scan the barcodes. If you are entering by hand, look at the two tables that follow. The first table lists the ROM IDs of all currently known modules and the second longer table lists the function IDs for all modules that have been mapped. (Thanks to Tony Duell and Steve in Australia for determining these mappings.)
Once you have a function name you can press XEQ [alpha]name[alpha] to enter it into your program. This assumes that you have the module installed. If you don't, the calculator will display NONEXISTENT. It generally won't be useful to enter an XROM instruction without the corresponding ROM, but it is possible to do it via synthetic programming, If you run the program without installing the ROM, the calculator will stop and display NONEXISTENT when the XROM instruction executes.
If you can map any additional modules, please send the mappings for inclusion here. To map the functions of a ROM, write a program which XEQs each function in the ROM, turn the calculator off, remove the ROM, turn the calculator on and inspect the program. Each function name will be replaced by an XROM rn, fn statement.
