This is my first post, so if I am being rude, please feel free to let me know.

I would like to have a couple of Classic HP calculators repaired. In my particular case, it is a/an HP-65, and possibly a HP-80. I'm not sure what is wrong with the HP-80, but the HP-65 won't read the magnetic cards. It pulls them through properly, but doesn't seem to read them (no doubt it doesn't write them either, but I can't really tell).

The 65 may only need head clean if the cards are going through ok, and the rest of the calculator works. Some of the presaturated cards for cleaning card swipe machines might work if cut to the required width. Otherwise, disassembly may be required and the head can be cleaned with a cotton swab and some isopropyl alcohol.

Do you have any more info on why the HP-80 is not working?

cheers
