HP-41 Copy files from Hepax ram to 41 - Jotne - 07-29-2017 04:53 PM

Hi

Is there a way to copy program from the Hepax RAM back to the HP-41
I do miss a HGETP as option to HSAVEP.

Sine I have a corrupt file in one Hepax RAM file on go41cx, I would like to get it back to the HP-41, so I can create a new RAM file and copy it back there.

I am not sure if this will work with a corrupt file... but normally the HP41 COPY function is designed to copy a FOCAL program from ROM to RAM. HEPAX treats programs in its RAM as ROM programs, so I think the standard COPY command should work here. If not, maybe some other expert on HEPAX can chime in!

Greg is correct here, COPY "PRG-NAME" will copy your program (PRG-NAME) from the HePaX RAM to main RAM.

Now if your HePaX RAM is corrupted, you can either
  1. with the help of the users manual file system information, use HEXEDIT to hopefully correct the invalid entries
    or
  2. try to save all your programs & data from HePaX RAM to main/offline memory and then reset HePaX RAM

HePaX RAM brute force reset & assuming HePaX RAM are between page 8 and 11
  • "OK"
  • 8
  • CLRAM
  • 9
  • CLRAM
  • 10
  • CLRAM
  • 11
  • CLRAM
  • OFF
  • ON
  • HEPDIR (should give you the message H:DIR EMPTY)

It worked nice. I do have the program on other RAM, so I can make all back to one healthy module.
