What is a 73K file?
A 73K file is a Flash application that can be run on a Texas Instruments TI-73 graphing calculator. Users install 73K files using Texas Instruments TI Connect.
More Information
The TI-73 graphing calculator is designed to be used by middle school students. Texas Instruments released the original TI-73 in 1998; it released a follow-up model, the TI-73 Explorer, in 2003.
At this point, most students use a TI-83 or TI-84 calculator in place of the TI-73. Thus, 73K files are uncommon. Developers typically write the programs 73K files contain using Texas Instruments' TI-BASIC programming language, which is a variant of BASIC.
How to open a 73K file
You can use Texas Instruments TI Connect (Windows, Mac) to install the program a 73K file contains on a TI-73 calculator. For detailed instructions, refer to your calculator's documentation.
Teachers can also use TI-Navigator (Windows) to install 73K files on students' TI-73 calculators.
