Solution 11365: Compatibility of Programs Written for the TI-83 Family Running on the TI-84 Plus Family of Graphing Calculators.
Can I run programs written for TI-83 family on the TI-84 Plus family?
The TI-84 Plus family is fully compatible with the TI-83, TI-83 Plus, and TI-83 Plus Silver Edition. All TI Basic programs for the TI-83, TI-83 Plus, and TI-83 Plus Silver Edition should run on the TI-84 Plus family.Assembly programs that have been previously made for the TI-83 Plus should be compatible and work with the TI-84 Plus. However, any assembly programs made for the TI-83 will NOT work on the TI-84 Plus family without modification of the code.
