We had TI-89 calculators in school. You could load programs on it to show, step by step, how to do quadratic equations. Another teacher in a history class was more manipulable and the students convinced them to allow us to bring in calculators to calculate the difference between dates, and they agreed. So we loaded our calculator up with notes from the computer.
