Hello Folks
First time poster.
I live in the UK and have been a keen HP calculator user and then collector since my first HP (an HP-31E I got new in 1978).
I have this HP-41CV for about ten years. Stupidly some years ago I left it with battaries in that leaked and damaged the foil around the leftmost battery connection (when viewed from below).
So took it apart and with a bit of soldering managed to fix it and it has been worked fine since then.
I got it out again to use it today (it gets used a few times a month) and just for fun ran a 'cat 2' to list the contents of Financial 1 I have in port 1 but it doesn't list the PAC contents. I removed the PAC and tried a Math PAC I have but it doesn't see that either. I tried it in the other ports and that doesn't work either.
I suspect this may be something to do with the original battery leak and am debateing whether I should try a new battery/port foil from Calculator store.
Anyone have any advice?
Regards
