Free Ti-89 Titanium Calculator to a good home 18 years ago
I'd be happy to take it off your hands. I've got a few more math classes to go, and the higher-level CS stuff. I don't know how much that requires an 89, but symbolic integration/differentiation never hurt anyone. AFAIK it would be useful for crypto stuff, which I've been thinking about getting into.
