This project contains programs I coded directly on my TI-83+ graphing calculator between roughly 2001 and 2004. At the time, there didn't exist (or I didn't have) programs and applications that perform the very basic (pun intended) functionality in these custom programs. As such, these programs probably aren't very useful to anybody today. However, I wanted to archive them for posterity, so here they are.

I transferred the programs from my TI-83+ using a TI Graphlink USB device and the TiLP software on Ubuntu Linux 16.04 LTS. The raw 8Xp files are located in the 8Xp directory.

In order to view the TI-BASIC source on the computer, I decoded the 8Xp files using SourceCoder. The decoded sources are located in the src directory. These sources are what you see when you load the programs onto a TI-83+ and view them with PRGM -> EDIT.

• AREAVOL: Print area and volume formulations for some geometric shapes - triangle, cylinder, pyramid, sphere, and cone.
• DELVAR: Delete cached variables from calculator - A-Z, theta, L1-L6, etc.
• QUADEQ: Compute solutions to the quadratic formula by inputting A, B, and C (for a polynomial Ax² + Bx + C).
• TEMP: Convert between Celsius, Fahrenheit, and Kelvin temperature scales.
