The ClassWiz features a high-resolution display - making it easier to view numerical formulas and symbols. The ClassWiz makes it possible to display on the screen twice the number of characters in normal size and six times the number in small size compared with previous models. A high-performance processor and twice the memory of previous models ensure speedy operation and superior computational power.
