A computer is a machine that can be programmed to Execution (computing), carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as C ...
s manufactured in
Wrocław,
Poland. The name comes from the
Odra river that flows through the city of Wrocław.
Overview
The production started in 1959–1960. Models 1001, 1002, 1003, 1013, 1103, 1204 were of original Polish construction. Models 1304 and 1305 were functional counterparts of

1905
As the second year of the massive Russo-Japanese War begins, more than 100,000 die in the largest world battles of that era, and the war chaos leads to the 1905 Russian Revolution against Nicholas II of Russia (Shostakovich's 11th Symphony i ...
and 1906 due to software agreement. The last model was 1325 based on two models by ICL.
The computers were built at the
Elwro manufacturing plant, which was closed in 1989.
Odra 1002 was capable of only 100–400 operations per second.
In 1962, Witold Podgórski, an employee of Elwro, managed to create a computer game on a prototype of Odra 1003; it was an adaptation of a variant of

, as depicted in the film ''
Last Year at Marienbad''. The computer could play a perfect game and was guaranteed to win. The game was never distributed outside of the Elwro company, but its versions appeared elsewhere. It was probably the first Polish computer game in history.
The operating system used by the Odra 1204 is called SODA. It was designed to work on a small computer without magnetic storage and
can run simultaneous loading and execution of programs.
An Odra 1204 computer was used by a team in
Leningrad developing an
ALGOL 68 compiler in 1976. The Odra 1204 ran the syntax analysis, code generation ran on an

Up until 30 April 2010 there was still one Odra 1305 working at the railway station in Wrocław Brochów. The system was shut down at 22:00 CEST and replaced with a contemporary computer system.
