There are many sites with programs for TI Graphing calculators. Some of the programs found in different sites might be zipped. It is important to note that zipped files may not be Unzipped at Cuyamaca College. To download zipped files to your TI Graphing calculator, you have to download the zipped files to a "31/2 Floppy (A:)" disk, and take them elsewhere (like home) and unzip them. Save the unzipped files and bring them back to college and use the instructions to download the unzipped files to your calculator.

• Downloading Programs from the Internet to the "H:" or "31/2 Floppy (A:) Drive"
• Downloading Unzipped Programs from the "H:" or "31/2 Floppy (A:)" to TI Graphing Calculator

1. Log on to your computer account
2. Open Netscape or Internet Explorer Web Browser
3. Go to http://www.ti.com/calc
4. Under Texas Instrument heading there is a menu bar. Look for Search and then click Free Downloads under it
5. Look for Calculator Programs: and click Calculator program Archive under it.

The archive contains calculator program, group, etc. files as well text files that contain the authors' documentation. A typical file grouping might look like this:

myprgm.83g

myprgm.txt

Each calculator folder contains a README file with a listing of all available programs in that directory.

6. Under Graphing Calculator Programs: click your TI-Model Number to open the respective program archive for that model number
7. Click on the program folder that you are interested in

- Not all TI-Model Numbers will have all the program folders

8. The program folder showing all the available programs will open. Information about each program may be read if you double click on the respective *.txt file (* stands for the program name.) After reading the text, close the text window
9. When you find a program that you want to download, simply CLICK on that file name (a file name will look like "theprgm.83g", "theprgm.92p", etc. Files ending in "g" or "p" may be downloaded. p stands for a single program file while g stands for the files with a group of programs..). Your browser is likely to respond in one of two ways:
   
   • If your browser displays the file (you may see only garbage or very little at all)...open the File menu and select Save As from your browser's menu, then continue with the instructions from step 10.
   • If your browser automatically displays a File Download dialog box ... select Save this file to disk option, if it is not already selected. Click OK in the dialog box and continue with the instructions from step 10.
     Dialog box: "Warning there is a possible security hazard here." Click Save to disk, click OK, and go to step 10.

     Note: You can automatically bring up the Save As window by "right-clicking" on the file.

10. Save As dialog box opens. Open the Save in: drop-down list box and select either H: (your mail address) or 31/2 Floppy (A:). Click Save, wait until the download is complete, and then close the dialog box.
11. Downloading is complete. Close or minimize your internet connection.

As explained earlier, there are many more sites with programs for TI Graphing calculators. More programs may be found on the left side of the Calculator Program Archive page (about half way down, under Other Program Archives) at http://www.hsu.edu/faculty/lloydm/ti/prgmtabl.html or TICALC.ORG http://www.ticalc.org/.
