It was just a thought...it'd be kind of cool to run linear equations, and just practice on the BASH shell for scripting and such...sort of like a bare bones BASH shell for TI (TInix...hehe...) I don't know the archetecture of TI's Hardware/ Software. I know you can write BASIC programs and another language also that is a little more versatile (APPS on TI83+/89/93)...anyways it was just a thought....thanks...
