Historic Russian computer. View of part of the Ural-1, a computer built in Russia in 1959. Ural-1 used thermionic valves and could perform 12,000 floating point operations per second - a million times slower than a modern desktop computer. It was used for a variety of mathematical problems and as a test-bed for future technologies. Ural computers needed about 100 square metres of floor space. The early Ural computers were superceded by transistor-based models from 1964. Photographed at the Moscow Polytechnic Institute in 2008.
