Description

Brand: Casio

Batteries: AA x 4
Lifetime: Introduced: ca. 1976

Notes: A Casio scientific calculator with a fluorescent display, and a slider to switch between modes.

This calculator has separate keys for the exponent and the constant π instead of the combined key of most other scientific calculators by Casio (where the "EXP"-key will enable you to enter the numbers exponent when you first enter digits, and will otherwise enter the constant π).

There's also no "INV"-key, only an "arc"-key for the inverse trigonometric functions. Statistical functions are available when the mode selector slider is all the way to the right.
