Is it possible to overwrite a write protected card on the HP-67? I have two Standard Pacs for the HP-67/97 but one has a couple of cards that give errors.
I thought I could just load the programs and then overwrite the card that would not read properly but I don't see anything in the manual about doing this.
Is this possible?
Second option: Can the 41 load such a program and write it back to the card using 67 instructions?
