is a computer series built in Soviet Union
The Ural was developed at the Electronic Computer Producing Manufacturer of Penza
in the Soviet Union and was produced between 1959
. In total 139 were made. The computer was widely used in the 1960s, mainly in the socialist countries
had three, for example—though some were also exported to Western Europe
and Latin America
Models Ural-1 to Ural-4 were based on vacuum tubes (valves), with the hardware being able to perform 12,000 floating-point calculations per second. A binary, single-headed device. One word consisted of 40 bits and was able to contain either one numeric value or two instructions. Ferrite core was used as operative memory.
A new series (Ural-11, Ural-14, produced between 1964 and 1971) was based on semiconductors.
It was able to perform mathematical tasks at computer centres, industrial facilities and research facilities. The device occupied approximately 90-100 square metres of space. It consumed triphasal
flux (380V±10%/50Hz) and contains a triphasal magnetic voltage stabiliser with 30kVA capacity.
Keyboard unit, controlling-reading unit, input punched tape unit, output punched tape unit, printing unit, magnetic tape memory unit, ferrite memory unit, ALU (arithmetical logical unit), CPU (central processing unit), power supply unit and electron tubes (6N8 type).
- Charles Simonyi, who was the second Hungarian in space, stated that he would take old paper tapes from his Soviet-built Ural-2 computer into space with him: he kept them to remind him of his past.
