They have a ramp-shaped piece of plastic shoved onto the back of the TI-85,
directly behind the LCD. The projector panel and the TI-85 are permanently
attached... my school has one of the jobbies. I tried ZShell on it, and
it appeared on the overhead projector, in fact, we had a big Tetris
tournament on the overhead :)
This was an older calculator tho, with ROM 5.0 or something like that. I
suppose they could have a different design in a newer calculator, maybe
even a jack so you can detach the projector panel & cable and walk around
with a plain 85...
