Picture: Casio FX-502P
Batteries: LR 44 x 2
Lifetime: Introduced: 1980
Terminated: unknown
Notes: The Casio FX-501P and Casio FX-502P were identical calculators except for the number of available program memory. The Casio FX-502P is the non-alphanumeric predecessor of the Casio FX-602P. I've never actually used this calculator. I got it by exchanging it with a Casio FX-601P I owned with someone who preferred alphanumeric above memory.

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.


There are various interfaces for this calculator (and others in this series). There are two types of cassette-interface, which could play musical notes as well. There is also a printer, the FP-10. I own the printer FP-10 and cassette interface FA-2.
