What are some alternatives to the TI89 calculator software?

[psycovic23]

Hey,
Right now, my beloved TI89 is off in another country, so I was wondering if anyone knew of an open source calculator software that functions sort of as easily as a TI (not like Mathematica or something). Thanks.

Try maxima.

I've never tried this:

EDIT: you can also try TI99SIM.
