Math Pac

[Leviset]

All please forgive an old time programmer (now retired) who cut his teeth writing programs for the HP-97 in the early 80s in the UK. A very kind man from Harrowgate gave me his unused HP-41CX complete with case and both manuals plus 2 X-Memory cards in 2 of the 4 available slots. He bought it in the 1980s in Singapore but it was never used as he had a work one as well.
My question is I know you could (can?) get different Pacs to slot in. The one I want is the Math Pac. I've recently bought the full $40 usb stick from the HP museum. Am I right in thinking that somewhere on there I'll find all the programs that were in the Math Pac and at worst I could rekey each of them and store them on one of my X-Memory cards basically creating my own Math Pac? Is there any way to copy the programs from the usb stick straight to the X-Memory card? Any guidance would be greatly appreciated as I doubt I can actually buy the Math Pac.
Thanks
