Engineering doesn't allow any calculators during math tests at all (at least when I was there).
Those courses that allow calculators are not aimed at teaching you how to count. Instead they are aiming at teaching you the logical engineering process, which is proven by showing the full solutions to the problem. If your way of thought cannot be traced to the answer, you get an F for that question.
Clearing the calculator memory is kind of a hustle, because of the point above. They don't grade your answer, they grade your solution, which makes saving functions pointless.
Were the newer calculators becoming too advanced or something? I just want nice user interfaces and fraction inputs (but I'll admit, ability to invert 3x3 matrices was pretty nice)
I'm pretty sure we had 3x3 matrix inversion in the MS calculator as well.
