Any suggestions?

Look at the actual board with the memory on it?

Good steer. Unfortunately this is the most inaccessible of the lot;
sandwiched up against the top display module it's impossible to see
what's in there without further disassembly. But now you have
suggested it, I think there's no other obvious course of action here.

Am I still looking solely for a supercap?

If it, or a battery, is there, it will be obvious and likely mounted
on the through-hole side of the board.

Niether are small parts, just low profile.

OK, got it, thanks.I'll investigate further tomorrow..........
