Can it do anything non-trivial? The algorithms for symbolic integration are extensive.

My Casio could do numeric differentiation and integration. I used this to double check my answers in my exams.

In fact, it still can as I still own and use it to this day.

It's quite good for what it is. Of course it will lose to Mathematica but I used mine heavily throughout physics to derive things symbolically.
