CASIO fx-140

Description

Brand:	CASIO
Model:	fx-140
Type:	Scientific calculator
Picture:
Batteries:	AA x 2 (or NiCad battery pack NP-2M)
Lifetime:	Introduced: unknown Terminated: unknown
Notes:	Nice 10-digit scientific calculator with a fluorescent display. Present are the usual bunch of scientific functions but also a fraction key. A slider is used to switch calculator modes such as the angle mode and to enable statistical functions. Basically this calculator is the 10-digit version of the CASIO fx-39. The calculator shows 10-digits normally and 8-digits when scientific notation is used. This calculator (as do many other CASIO scientific calculators) uses one and the same key for both the constant π as well as exponents. This works as follows. When you first enter digits, the EXP key will enable you to enter the exponent, otherwise it will enter the constant π. Many thanks to my father-in-law Joop Berck, for donating this nice calculator to the museum. Joop unfortunately is no longer with us and is deeply missed.

A power adapter (AD-4145).
