Casio - fx-8100

Description

Brand: Casio
Model: fx-8100
Type: Scientific calculator with clock and stopwatch
Picture: Casio fx-8100
Batteries: SR 1130 x 2
Lifetime: Introduced: unknown
Terminated: unknown
Notes: This calculator doesn't only do your basic scientific calculations (including the famous Casio fraction key, and statistical functions) also keeps the time, has a stopwatch and timer and two time-alarms.

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 numbers exponent, otherwise it will enter the constant π.

According to the Casio web site, all Casio calculators are millennium-proof. That page is no longer there but I've saved it and you can view the saved page here. It also states that pre-1994 models might not be millennium-proof, I don't know then the Casio fx-8100 was introduced.

When the year leaps from '99 to '00 the calculator won't display the date anymore. Any attempt to get the date results in an error "E" display.

Take a look at the Casio fx-8000 too, which falls in the same category as this calculator.

I would like to thank RoB Beekmans for donating this nice and popular calculator to the museum.
