Hi all,
I'm trying to repair an HP-65 calculator, but it's exhibiting a strange behaviour. Every 2nd key I press it displays 9.99999999E99 ... or something like that.
So, if I press '4', 1st it displays the 4, then if I press '4' again it displays 9.99999999E99.
I opened the unit and I noticed the yellow cable near the card reader is out of it's place (I think this is not the problem cause it only affects the card reader, right?) anyway, can anybody tell me were the yellow cable plugs?
The part unplugged is unfortunately inside that foam rectangle, and I have no idea were I should put it :s
Thank you all,
Bruno
