RE: Should I bother? HP-34C in rough shape
As there seems to be same oxidation (blue copper) on the flex cable as well:
Did you check these go thru to the electronics?

--> Cathode (upper battery contact) vs. 6th connection counted from the left of the flex cable as you look on it
--> Anode (lower battery contact) vs. 3rd connection of the flex cable counted from the left as you look on it
--> Rivet in the middle between the battery contacts to left most connection (but not so important - is cathode from charger for charging electronics AFAIK). If this one is not connected / goes thru you can not charge the batteries inside the calculator.

If all connections ok you have to disable more I guess. But yours is the soldered (therefore the more reliable) version as I can see from the pictures.
