41c native user program hex dump - Craig Bladow - 05-23-2018 11:51 PM

Does there exist a 41c program that will dump the bytecodes from another program in memory? Bonus points if the output is on an HP 41 compatible printer. I know I can go the IL->9114b->floppy->sneakers->PC to lifutils route or use an emulator but would like something native to the 41c.

Did you check the PPC ROM manual? I believe there is a program in there that does that (or function that could be used in a larger program), though I could be recalling a program from the PPC Journal; it's been (too) many years...

Wickes' book on Synthetic programming has a program called "backtalk" that will translate data in the 14 byte X register into readable characters in the alpha register. I will check the PPC ROM manual and if the routine exists, hopefully there is a listing, or better yet, bar code.

Not in the PPC ROM manual... Finding it in the PPC Journal will take a little longer..... Smile

V10N4P29_HP-41C_Direct_Byte_Listing_of_Programs

Best I could find. Requires extra modules.

Thanks Gene! Unfortunately I don't have any of those modules.
