Casio fx-82SX

Brief History
CASIO has developed a brand new scientific calculator circuit in the end of 1980s, which computes transcendental functions at much higher speed. The technology called Super-FX was used in the revisions of current products in the next years, so the cheapest scientific calculator, the fx-82 has been modified in 1994 to use the Super-FX technology. The fx-82 SUPER has capacity of displaying 10+2 digits, and can calculate combinations and permutations too. The facelifting version was introduced in 1996, the fx-82SX got a new design and a sliding hard case.
