Casio fx-180P

An archetypical programmable calculator from Casio, the fx-180P has many of the distinguishing features found in the vast majority of non-graphing programmable Casio calculators. 38 merged program steps, 6 registers plus one "independent" memory, a simple programming model that nevertheless provides for conditional execution, and an uncluttered keyboard offering a comprehensive set of scientific and statistical functions characterize this model and many of its successors.
