With all these links, I sincerely hope you’ll have your own TI-83
model. The rest is up to you. Good luck and thank you very much!

Sincerely,

Feilong

There's a TI emulator for your computer downloadable at http://www.ticalc.org

Just to complement Feilong's fine research with a "brick and mortar"
approach, try office supply places (such as Office Depot, Staples, or
similar), any university/college bookstore or educational supply
store, or (with only slightly less chance of success) some general
back-to-school retailer (like Kmart, Walmart, Sam's, etc.) or
drugstore (sundries).

I had occaision to make just such a purchase last spring for our
oldest child, the day before his big math final.  It worked (he
graduated)!
