Elwro EW-116 – A calculator from the future?
Some time ago I talked about one of the first calculators produced in Poland – Elwro 105LN, today it’s time to look at one of its successors.

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.
Unitra K-765, or Commodore in Polish guise
During the communist era, pocket calculators were produced by two companies – Wroclaw’s Elwro and Bydgoszcz’s Unitra Eltra. We will take a look at the constructions made in Upper Silesia at another time, today’s hero will be a somewhat strange and already forgotten construction from the Brda River.
CWD351 – Digital LED indicator from the communist era
Since its inception, all digital machines were meant to serve man and help him perform his daily tasks in the office, on the factory floor or at home. However, in order for a machine to be useful, something was needed so that humans could understand it. Nowadays, it is quite normal to have all kinds of screens on which digital systems display information that we can understand, but this was not always the case.
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.
