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

Sorry for not replying earlier.

The HP-80 is in transit from Greece at this time. As you probably can tell from my name, I am of Greek origin, and have extended family still there. They found the HP-80 at what would best be described as a flea market. It had no charger, so it can’t be powered up, and I asked that the (very) corroded battery pack be removed and discarded. The calculator appears to be in good (not museum grade) condition, with some average wear. I can’t say with any certainty whether it is functional or not. I do have one of Mark Hoskins’ battery packs that can use disposable AAA batteries on the way to allow me to power up the calculator when it gets here.

This is all I know at this point (aside from the two feet at the rear bottom are missing, which concerns me greatly). I am hoping that it will simply power up and work, but it may not. I just have to wait 4-6 weeks for it to get here.
