Reading old HP-65 program cards

[Gene Dorr]

Does anyone have any experience or advice with respect to reading really old (ca. 1975) HP-65 program cards?

The National Air & Space Museum has in their collection the program cards that were used on the ASTP space flight in 1975, and I'm wondering whether there is actually any chance of being able to read them. It's doubtful they'd allow anyone to even try... but I'm just trying to determine if it's worth trying to convince them.

I understand the rollers degrade quite badly over the decades, so I wouldn't attempt with the HP-65 in their collection -- that would probably have a horrible outcome for both the calculator and the cards.
