Thanks for the information. I also found some values in this thread.
Here is a capacitor with 1.5F: EDLSG155V5R5C which would fit into the calculator, if I cut out the inner cover. I think the biggest problem is not the capacity but the internal resistance of the capacitor. It is 30 Ohm which causes in a voltage drop of 0.3V @ 10mA.

@Marcus: Do you know the voltage threshhold at which the calculator resets?
