БэСМ (Большая зледектронно-счётная машина, Big Electronic Calculating Machine)

BESM is a USSR computer, which was developed in the mid-1960s and was actually built in 1967 by the Institute of Precision Mechanics and Computer Engineering, ITM and VT, IPMCE.ru) and features Sergei Lebedev (Sergei A. Lebedev was the head of the design team, with Lebedev taking over as head of the design team in 1951.

The 1953 BESM-1 was built into a 39-bit computer using approximately 5,000 vacuum tubes. Mercury tubes (RAM) can process 10,000 orders per second (IPS), which is considered to be the highest speed in Europe at that time.

1957 BESM-2 was developed similar to BESM-1, but converted to an interchangeable magnetic tape memory.

BESM-6 is one of the best-known Soviet computers because BESM-6 is applied to a number of key projects such as the Apollo-Soyuz Project (1975).

BESM-6 HAD A SPEED OF ABOUT 1 MIPS, WHERE THE MOST ADVANCED U.S. COMPUTERS AT THE TIME, THE CDC 6600, HAD A SPEED OF 2 MIPS.

In 1987, the Soviet Union terminated the development of the BESM-6 computer, but instead developed the Elbrus architecture.

Over the course of twenty years, a total of 355 BESM-6 machines were built between 1968-1987.

After the collapse of the USSR, almost all the BESM-6 was destroyed for sale. The complete BESM-6 was not left in Russia, but the most complete BESM-6 was bought by Doron Swade and is currently preserved in the Museum of London.
