What is a 73P file?
A 73P file is a program that can be run on a Texas Instruments TI-73 graphing calculator. Typically, 73P files contain utilities or video games. Users install TI-73 files with Texas Instruments TI Connect.
Middle school students use TI-73 series graphing calculators, including the TI-73 and TI-73 Explorer, to plot graphs, solve equations, and often, play video games. Students can install additional programs on their calculators using the devices' associated TI Connect software. Most TI-73 programs are saved as 73P files. (Some are instead saved as .73K files.)
Sometimes, teachers distribute 73P files to students, so students can install them. Students can also download 73P files from online TI graphing calculator program repositories, such as Cemetech.com.
NOTE: Some TI-73 programs consist of multiple 73P files. Typically, all a program's 73P files are packaged in a single folder.
How to open a 73P file
You can use Texas Instruments TI Connect (Windows, Mac) to install the program a 73P file contains on a TI-73 calculator. For detailed instructions, refer to your calculator's documentation. Note that, if the program you want to install consists of multiple 73P files, you must install all the files for the program to run.
