I have almost all the HP-65 & HP-67 application pac in my collection.
Several cards, about a dozen, are not working anymore and nothing can revive them.

Thank-you Sylvain (sob....)
Aaaarg..... so the only way is to write onto a new card, entering manually each line of the program, step by step and using the original card merely as overlay for the A, B,C, D,E keyes
