This Casio AL-8S introduced in 1976 followed the
AL-8, the first hand-held
calculator operating and displaying fractions. The not very intuitive approach
with a [P] key for six pre-programmed functions accessible through a larger
slider switch called "Function Mode Selector" was replaced with dedicated [a b/c], [SQR], [GT] and [DATE] keys. Unfortunately lost the AL-8S with these
changes its unique time / angle statistical calculations.
Dismantling this
Casio AL-8S calculator manufactured in 1976 reveals a design centered around a
Hitachi HD36133 single-chip calculator circuit while its predecessor AL-8 and sibling
AL-10 used a NEC uPD573C part.
