RE: HP12C battery contact question
Well, thanks very much for the replies to my post. They were pretty much 'spot-on' and gave me the confidence to safely repair the calculator. After a good IPA clean around the PCB tracks, I managed to solder a short piece of 24 SWG tinned copper wire onto the track and then bend it to form a new contact for the battery's -ve terminal. All is now working perfectly. Particular thanks to jonese who identified an alternative connection route if the original track couldn't be repaired - so far, not required!

Many thanks to all for their help, Mike
