TI Tools is a CLI tool designed for converting 8xp files (used by TI-83 and TI-84 calculators) to text files and vice versa. It also supports various other features for working with 8xp files.
Our top pick is the Texas Instruments TI-84 Plus CE due to its rechargeable battery, fully backlit color display, and lightweight design, allows students to carry it in their backpacks easily.
