RE: Why do some HP calculators have springs inside?
OK so my 12CP doesn't have springs but it has a quartz crystal, I wonder what the quartz crystal does in the calculator? There is neither digital clock nor chronometer function.

The only reason I would think is that the quartz crystal has something to do with the screen's adjustable contrast?
