Here you will find some graphing calculator resources with an emphasis on doing statistics with older or odder models. Do not forget the calculator manuals which are actually pretty good. In the unlikely event that a student has misplaced their manual you can download PDF versions from TI. Their site is a moving target so try a Google search.
If you or a student has a TI-86 or TI-89/92 calculator, you need to download and install a statistics program for it. The Statistics with List Editor App is available for the TI-89, TI-89 Titanium, TI-92 Plus, and Voyage 200 from the TI website. You can find a manual for the statistics package on this same page. Older calculators may need an operating system upgrade as well.
TI no longer supports the TI-86. Here is a link to the TI-86 program. Once you have one TI-86 with the program it is easier to link it from one calculator to another. Documentation for the TI-86 stats. package seems to have disappeared from the TI site but can be found here.
TI-82 & 83 Calculators
Eventually I tracked down the author once again and asked him if I could post his resources on my web site so that others could find them. Here is his response with links to the newer materials.
