The M-2 was assembled in the period from April till December 1952, upgraded until 1956, since 1953 solving applied tasks on round-the-clock basis with fixed and [[Float|floating point]] numbers. Instructions were 34-bit wide, had [https://en.wikipedia.org/wiki/Three_address_code three address codes] and 4-bit opcode. The control circuit and [[Combinatorial Logic#ALU|ALU]] used [https://en.wikipedia.org/wiki/Vacuum_tube tube] and [https://en.wikipedia.org/wiki/Semiconductor semiconductor] [https://en.wikipedia.org/wiki/Diode diodes]. The internal storage devices included the main electrostatic device (standard cathode-ray tubes) that held up to 512 numbers and had regeneration cycle of 25 µs, and an additional magnetic drum that held up to 512 numbers and rotated at 2860 revolutions/min <ref>[http://www.computer-museum.ru/english/m2.htm The Fast Universal Digital Computer M-2] by from the [[Russian Virtual Computer Museum]]</ref>.
