50g

There used to be something for the hp48gx...

But I kinda doubt that hardware will work with the 49g+ or 50g, as the serial port in them is funky. Still, worth investigating.

Simpler still would be to use an emulator like EMU48 on a PC and a projector that can take input from a PC, skipping the calculator entirely. In fact, HP suggests using an emulator for classroom presentations...
