RE: HP12C battery contact question
It's not really a added cap covering the board stub, it's just the same material (copper/gold?) that they had used for the traces on the rest of the board. Is it just worn away? Corrosion?

The NEGATIVE connection stub is carried underneath the board (the part you can't see) and is actually connected to the top via hole just to the left of the top portion of the through-hole cap in your first post's picture. Next to the small spring cavity?

You could make a small wire connection to the battery compartment to complete the circuit.

I'll see if I can post a photo of the bottom of the board for clarification.
