Casio - DUAL LEAF SL-200


Brand: Casio
Model: DUAL LEAF SL-200
Type: Calculator
Picture: Casio DUAL LEAF SL-200
Batteries: Solar cell
Lifetime: Introduced: unknown
Terminated: unknown
Notes: This "DUAL LEAF" calculator folds up to a small package that easily fits any pocket. This has the advantage of getting bigger keys and a better display into a small calculator.

This calculator has basic functions, a change-sign key, percentages and square roots.

The calculator thinks √-9 = -3 which is very uncommon for calculators newer than the early 1970's.

Thank you, Paul Coenen, for donating this calculator.
