Mmmm... HP28, my favorite calculator ever. 

Hey, what were the TI calculators that people added switches tacked on to
the secret pins to get the functions of the next model up? I remember seeing
3 radio shack pushbuttons sticking out of the top to get x^2, 1/x, and
square root or something like that.
