Graphing Calculator Models
Texas Instruments has released ten different graphing calculator models over a period of nine years. Here they are in order of release date.

The TI-81 has been discontinued and is no longer in production. In the future, this could happen to the TI-80, TI-82, TI-83, and TI-85 as well, since they are being replaced by the TI-73, TI-83, TI-83 Plus, and TI-86, respectively.
