This page points you to step-by-step procedures for several tasks on the TI-83; some procedures also show steps for the TI-89. (Keystrokes for all current models of TI-83 and TI-84 are nearly identical. Keystrokes are similar between the TI-89, TI-92, and Voyage 200.)
By the way, if you need to buy one you’ll find it at the College bookstore; at big retailers like Staples, Wal-mart, K-mart, and Office Max; and through Internet sources.
