Hi all you HP calculator specialits,
I read the article at www.rskey.org/hp97reader.htm on how to repair the HP97 transport wheel in the card reader. A very good article! I managed to do all the necessary steps.
My problem: I didn't find the right silicon tube. It seems that the inner and outer diameter as well as the hardness (40 shore or more..?) have to fit exactly. All the different tubes I tried didn't transport the magnetic card!
Question: Could anyone possibly send me a piece of silicon tube that works? I would appreciate that very much and could also send him some dollars to compensate for his expenses.
My address:
Mr. Martin Baumgartner

Kind regards
Martin
