Revisiting the TI81
The TI81 is not quite as feature full as the HP 28C, however it was the calculator that got me into graphing calculators.

RE: Revisiting the TI81
I remember it fondly. Bought it at the end of 1991 and wrote a program to convert matrices to reduced row echelon for my Linear Algebra class in university. Still have it and use it.
Everything will be alright in the end. If it's not alright, then it's not the end.
