Hi All,
I purchased an old HP-41C off of e-bay - and, basically, the condition of the unit was much worse than I was lead to believe. I guess I should have insisted on seeing a picture of the battery contacts - all 4 are quite corroded. I'm not sure, this HP-41C looks like it might be the "tall key" model. It has a serial number of 2037A00417. It has a battery pack that looks to be in not very good condition and no charger was included. All the keys have a good click except for the "1" key - it seems to not return to the correct position unless you manually, gently, pull it back. I also picked up an HP 82143A printer. Initially nothing happened when I plugged it in and I thought it was dead. But after 4 or 5 minutes now both the "Bat" and the "on" light are lit - so perhaps this unit will actually work. The battery has a "New" sticker on it - but that seems to convey little information since there is no date! ;-)
Does anyone know if the batter pack from an HP-41CV (that uses 4 N alkaline batteries) will work if plugged into the HP-41C (that originally came with a recarhgeable battery pack)? Any chance that the charger that came with the HP82143A printer will work with this HP-41C?
I am thinking about trying to find 4 small pieces of copper - and trying to solder them onto the existing contacts. Anyone know where I could find some copper that is very thin/flexible? I have never soldered anything in my life - I have a soldering iron - still in the shrinkwrap - someone gave me last Christmas. Anyone care to lay odds of success? ;-)
Thanks for any hints, tips or pointers to additional info.
Kevin
