What does ODRA stand for? 

Odra

Odra was a line of computers manufactured in Wrocław, Poland. 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 ICL 1905 and 1906 due to software agreement. The last model was 1325 based on two models from ICL. The name comes from the Odra River that flows through the city of Wrocław The computers were built at the Elwro manufacturing plant, which was closed in 1989. ODRA-1002 were capable of only 100-400 operations per second. 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 IBM System/360 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. Few Odras are placed on exhibition in museums and at least one is still operational and maintained by students of electrical school which created a fan club around the machine.
