I was just reading a PDF about the optical wand for the HP 41 series calculators.
And I started to wonder whether anyone has ever developed a software tool for converting program listings (maybe devloped on a HP-41 PC-emulator) into a barcode that can be printed and loaded into the HP-41 using the optical wand?
Using such a tool all you'd have to do is enter the program once on a PC, run the software and the result would be the barcode. This way you could store your programs either as a listing or barcode on your PC and print them out to upload them into the HP anytime you need them.
All I know is, that back in the "active days" of these calculators you could send a program listing to HP and they would print a barcode interpretation for you for relatively affordable amounts of money. Maybe this service has been ported to a software solution already?
Looking forward to your replies,
Timo
