If you like to use your overhead projector while teaching, and do not want to have your overhead occupied with the calculator viewscreen all of the time, the TI Presenter is an alternative option.

The Presenter connects your TI-83/84+ calculator (Viewscreen model) to a television set for a very sharp image of your calculator screen.  It can connect to any of the following:

1.   TV or a VCR with a video-in jack

2.  One of the newer LCD projectors for larger pictures

3.  Directly into a TV's antennae jack with a modulator (available from Radio Shack or other video vendors).

The cabling included with the Presenter can place you more than 20 feet away from your TV for easy classroom use.
