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.

|Second calculator built in Elwro
based on Japanese Busicom products, first widely manufactured.
Some units used Japanese hybrid VFD drivers, some Polish ones.
They were made with Futaba VFD tubes and probably Japanese
cases, as they have English markings about high voltage inside.
Not buggy, division by zero displays all zeros and can be
cleared with C key. Turning on is realised by lever, spring
released display cover and turns power on.
