Here are some programs I wrote for the TI-85 calculator (with the exception of the Prime Factorization Program, which I copied). They're saved in .85p format. To view this format, you need Texas Instrument's Graph Link software for either Windows or Mac. The programs are saved as .zip's, so you'll need to unzip them before you can use them. If you want to know anything else about TI-85 calculators, or if you want more programs, go to TICALC.ORG.
