Elwro 105LN – Is it really a Polish calculator?

The Elwro 105LN is one of the first office calculators to be produced at the Elwro Wroclaw plant. This device is a direct successor to the 105L model and, in fact, the first mass-produced one since the early 1970s. The design is very interesting both in terms of technical solutions, but also in terms of history, which is not so obvious.

Bolek and Lolek from Wroclaw

In my last article on retro equipment, I told you about a pocket calculator manufactured at the Unitra Eltra plant in Bydgoszcz. This time we will also take a closer look at a pocket design, or even several such devices from the times of centrally planned economy, with the difference that these will be calculators signed with the logo of Wroclaw Elwro.

Elwro 151 – The last evolution of the 144 model

A little bit of calculators were produced in socialist Poland. There were models dedicated to the ordinary Kowalski, scientific designs for professors, printing for accountants or pocket calculators for school children. The basic and probably one of the most popular models was the Elwro 144, a classic base design, on which quite a few other calculators produced by the Elwro plant in Wroclaw were based. Today I would like to tell you about the latest evolution of the 144 model, the Elwro 151 calculator.
