HP67 question

[aurelio]

@Steve Simpkin @ [kby]

Thanks for your comments.
I also thought I could solve through the HP41, actually instead of the optical wand through HP-IL, (the result does not change), but it's not possible for the reasons Steve explained, infact if you can read with a -41' reader -67's cards you can't play the same game vice versa ...

I read , after a try this old post
I wrote two very simple programs on the -41, which on the -67, are not recognized, the card reader requires additional cards (Crd).....

Doing viceversa, I've noticed that the -41 imports the -67's program adding two extra (prefix?) lines: LBL67 and LBL10
