On a second examination of the SE main board, I've noticed that the replacement of the soldered battery was performed at least once.

I'm having no luck with getting a good attachment of any wiring to the terminals of a 3.6 V 1/2 AA battery.  If I'm going to take the SE revival any further, I'll need to get a battery holder which will fit both the battery and the board.  Does anyone have a source for one of these?

If I can't get a holder, then I'll just dump the SE and redirect the effort towards getting the second SE/30 fully working.
