RE: Transferring programs to and from an HP41CL
After more thinking ...

Another option would be to use V41.
  1. 41CL
    1. map HEPAX ROMs
    2. map 1 to n QROM pages
    3. format them as one HEPAX RAM filesystem
    4. loop: copy your program from main memory to HEPAX RAM with HSAVEP
    5. when ready, transfert each pages with the serial interface and clupdate (or equivalent program) and save them as ROM files
  2. Computer
    1. create a MOD file with the transferred ROM file(s) (ex: my-apps.mod)
    2. create a v41 .lod file with the 41OS, HEPAX MOD and the new MOD files. (ex. my-apps.mod)
    3. start V41
    4. CAT 2 - to validate loaded ROMs
    5. EMDIR - to validate HEPAX RAM content
    6. loop
      1. COPY "PROGRAM NAME" - copy program name from HEPAX RAM to main memory
      2. v41 / menu / put user code / select main memory program / filename.raw
      3. CLP "PROGRAM NAME"


A similar procedure could also be done with a RAMBox ROM setup.
