Re: Reuse HP97/67 Magnetic Cards Message #7 Posted by Martin Baumgartner on 25 Dec 2002, 9:39 a.m., in response to message #1 by Martin Baumgartner
The real problem: The magnetic card reader of my retired fathers HP97 doesn't work anymore and I don't know how to repair it. He's been using this calculator since years ( geometrician). I wrote some very helpful programs about 20 years ago for him and now this work is lost (unreadable magnetic cards in the old HP97).
Personally I have a 42S with infrared printer. This unit has no PC interface an I would have to retype (and adapt) every line of code and then make a gift to my father. Quite a lot of work (and I will lose my 42S!). Also, if the batteries are empty and he doesn't realize it, I can retype the code of 20 magnetic cards!
The best and fastest solution would be to repair or replace the card reader of the HP97. I live in Switzerland and I don't know any nice person who could do that for me. Is it difficult the get a card reader for a HP97 and what are the risks when replacing/repairing it? What would be the price for a HP97 card reader?
Second best solution (but probably quite expensive and time consuming) would be a HP41 with card reader, printer and PC interface. But where can I find this combination for a realistic price?
Third best solution: HP48 with serial Interface to PC. But: what would be the effort to translate 20 magnetic cards to RPL?
Cheers.
