Here is a collection of half finished mix of TI-Basic programs I've created over the years. Most of the programs are designed specifically for TI-84 Plus CE, but there's a few TI-84 Plus ones in there. Go wild my friends.
Click HERE for a full list of my finished but admittedly barely maintained projects at Cemetech. Great guys if you're interesting in learning more about Calculators and other niche coding projects. TI-Basic Dev is also great, basically a complete documentation on TI-Basic.
Crash course for installing these projects for the uninitiated, basically everything revolves around Texas Instruments's TI-Connect, their IDE for Basic projects. Their you can use a mini-usb cable to connect your computer to the port on calculator and upload files.
