Reading old HP-65 program cards

[isanchez]

Hi,

The cards maybe dead or alive at the same time, as if I try to read them I can kill them, but if I do not try to read them I do not know if they are fine...(just joking, please, I do not want to open a debate! :-D

IMHO: I find the valuable issue is the registered code, not the cards. I have a couple of HP65 and they read 99% of the cards perfectly.

Regards

Ignacio
