Casio fx-95
Brief History
The fx-82 series planned for educational purposes was expanded from time to time, so the fx-82 Super with Super-FX chip allowing quicker calculations announced in 1994. Casio was developing some other machines using this chip, and differs in ROM: the fx-95 can solve quadratic equations and simultaneous equations instead of calculating combinations and permutations.
