Casio Computer Co., Ltd introduced with the fx-10 its first scientific handheld calculator in May 1974, almost 2 years after the Mini CM-601.
It took more than three years before in September 1977 the PRO
fx-1 their first and only hand-held programmable calculator with integrated
magnetic card reader appeared on the market. Technically is the PRO fx-1 based
on the fx-201P introduced already in 1976 and then competing with the
Timing of the market lunch of the PRO fx-1 was a disaster! While it could barely compete with the SR-52 introduced already in 1975, blew it the revolutionary TI-59 simply away.
Dismantling this Casio PRO fx-1 manufactured in January 1978 reveals an interesting design centered around multiple Integrated Circuits manufactured by Hitachi, Japan.
