CASIO fx-180P

Description

Brand: CASIO
Model: fx-180P
Type: Programmable scientific calculator
Picture: CASIO fx-180P
Batteries: AA x 2
Lifetime: Introduced: 1980
Terminated: unknown
Notes: The CASIO fx-180P is the programmable follow-up on the CASIO fx-80/CASIO fx-82 series design. It uses plain AA batteries and is therefore suitable for intense usage.

See also these successors, the CASIO fx-3500P and the CASIO fx-3600P.

This 10-digit calculator can store two separate programs with a maximum of 38 programming steps. Programs are just key sequences and can not be edited once entered. It is therefore important to use validated input data even when entering programs, for a program has to be re-entered when an error (invalid operation) occurs during programming. Simple loops were possible using the "RTN" operation.

It also has a wide range of statistical operations, including random number generation and two-dimensional functions.

It has the familiar M memory key function but also has six separate memory locations K1 - K6 that can be addressed using the Kin and Kout keys.

This calculator can also perform fraction calculations using thee fraction key, two types memories (K and M), and it can also convert between polar and rectangular co-ordinate systems.

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.

When a one-dimensional function is programmed under one of the programs, this calculator can calculate a partial integral of that function as well. This was really nice at school, you could verify the correctness your answer!

All in all quite a nice calculator, especially because in its time it looked just like one of the standard school calculators.
