CASIO fx-3500P

Description

Brand: CASIO
Model: fx-3500P
Type: Programmable scientific calculator
Picture: CASIO fx-3500P
Batteries: LR1130 x 2
Lifetime: Introduced: 1980
Terminated: unknown
Notes: This programmable calculator is functionally identical to its successor, the CASIO fx-3600P which has a different housing. Of the variants I personally prefer this model for its sleekness and its clean looks. For a description of this calculator’s functionality see the the CASIO fx-180P, a predecessor that is almost functionally identical but misses the hyperbolic functions.

Its housing is very similar to that of the CASIO fx-510 Scientific Calculator.

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 Willem Temmink for donating this calculator to the musem!
