New machine language port

[cahlucas]

Dear Mr. Horne,

I have now been able to compile / assemble the entire program. Unfortunately the program does not work. It seems that certain techniques that work on the HP-48 do not work on the HP-50. That's why I need a good machine language debugger for both the HP-48 and the HP-50. The problem here is that some pieces of asm code are embedded between code of sys-RPL. What is the best way to proceed? Are there certain procedures for porting from one calculator to another? Sincerely, Karel.
