According to Wikipedia Casio introduced "Visually Perfect Algebraic Method (V.P.A.M.), Natural Display or Natural V.P.A.M. input methods" with model fx-991S and other "S" series scientific calculators in Japan in 1998.These models are some years earlier than the fx-9860G which was introduced in 2005 (also according to Wikipedia).
