If you have the HP-41, HP-IL interface module, and either the card reader, HP-9114 disk drive, or the cassette drive, then the program can be copied onto the appropriate media. If the program is in subroutines, then it is possible that the HP-41 will not hold them all at once, but the subroutines can be copied one at a time. As far as another cassette, I sometimes see them listed for sale. The original price was around $10, and they seem to go for about that now, if you can find them. I got a few used ones from the Interfab liquidation, and some might still be available there.
