Thin, 10 digit, LCD calculator with the basic scientific functions and memory. It
can also perform calculations with fractions and do statistics. It even has a
random number generator.
This calculator was donated to the museum by Martin
Zámečník. Thanks, Martin! It was
sent to The Netherlands all the way from Czechia. Much appreciated.
This calculator has the distinctive blue memory buttons (which I quite like) that are also available on the SHARP PC-1403, the SHARP EL-506H (and probably others). |
