You can make a solar nametag with some parts of it. Google for BEAM NAMETAG.

Scrap the back of the display and you get a polarizer.

It's not much good for anything else but a calculator.

I've had one of those for 20+ years, but only used it as a calculator. So let's see if anything good is suggested.

The solar cell was used to keep the battery charged (so the calculator would work indoors or out). It probably didn't produce more than a few tens of mA at a couple of volts, but you could still use it for a small project (like a solar joule thief).

The LCD could be used as a display in a project, if you know the pinout. That would require some Web research based on any component numbers or labelling you find on it.
