Elwro Desktop calculators (3)

Page 2

The purpose of this page is to show only units which I have. Units which I don't have are covered in Elwro Desktop Calculators List.

Elwro manufactured these desktop calculators since 1970s. Early units were clones (some even using genuine parts!) of Busicom Japanese calculators. From simple 4-operation devices these calculators evolved to complex, scientific and in last models even programmable calculators, using not only western, but also Polish components.

WARNING: Technical parameters are parameters of the particular unit. These calculators were made in a hard times, when western components were not easily accessible. It means that some units may have modifications to use replacement components.
