Casio Computer Co., Ltd introduced its first scientific handheld calculator fx-10 in May 1974, almost 2 years after the Mini CM-601.
Casio named the fx-10 according to its set of ten scientific
functions, even in May 1974 rather disappointing. Please notice that it sports
the trigonometric functions sine, cosine and tangent but misses its inverses.
Compare the fx-10 with the SR-50
introduced in January 1974 and other scientific calculators available in 1974,
e.g. Canon F-7, Corvus
Model 500 and Hewlett Packard
Dismantling this Casio fx-10 manufactured in August 1974 reveals a clean design centered around a NEC uPD175C/uPD179C two-chip calculator circuit and a Toshiba T3184 display driver circuit.
