RE: HP 67 magnetic card not working
I dealt with the same issue a while ago when one of the cards in the Standard Pac that came with my HP-67 turned out to be unreadable. The card looked clean and undamaged, and I was able to restore it using the trick mentioned earlier using a card with a bit cut off to fool the write-protect switch.

In addition to what others have said, however, I would like to add two bits of advice: first, it took me several attempts before I had the card back to where it could be read without error, so don't give up too quickly if it doesn't seem to work; and second, after retyping the program, save it to another card first, because you don't want to have to retype the program again and again after every failed attempt. Smile

Good luck!
