Economical fast machine that ran 15 years around the clock
Between April and December, Kartsev's team builds the M-2, credited in the literature with about 2,000 operations per second and built with a fraction of the tubes of comparable machines. It computes for Kurchatov's atomic institute.
In Kartsev's new M-2 group she and Lavrenyuk design a 34-tube, 512-word CRT store with 25-microsecond access; the same year she marries M-1 chief engineer Nikolai Matyukhin.
Brusentsov graduates and is assigned to the special design bureau of Moscow State University. His final-year diffraction tables, published 1954 in the Vestnik MGU, are known as the 'Brusentsov tables' to this day. At MGU there is at first no interesting work, until his friend Kartsev shows him Bruk's M-2, which impresses him deeply.
Bruk put the fresh graduate in charge of the M-2 in spring 1952; by December all cabinets were switched on. At 2,000 operations per second it matched the Strela and early BESM, and it ran round-the-clock for fifteen years.
The M-2 enters operation with her CRT memory as its main store, enabling its 2,000 operations per second; ferrite cores replace it only three years later.
She joins Brook's Laboratory of Control Machines and Systems (later INEUM), programming the M-2 in Brudno's department and modeling brain activity on the side.
At the Moscow conference on 'paths of Soviet mathematical machine-building' she presents the M-2's electrostatic storage.
After the offended Bruk refuses to hand over an M-2 (Sobolev had voted for Lebedev, not Bruk, in the Academy elections), Sobolev declares: 'Let us build a computer for educational institutions ourselves.' At a seminar the task is formulated and Brusentsov named chief designer. Of Sobolev he said: 'When I first entered his office, it was as if sunlight floode
She writes the memory chapter of the M-2 book edited by Brook and enters the Institute of Automation and Telemechanics as a graduate student.
His monograph 'Arithmetic Units of Electronic Digital Machines,' grown from the M-2 work and his candidate dissertation, systematized arithmetic circuit design and was later republished abroad.
The young engineer headed the BESM-2 (germanium diodes, ferrite memory, construction unified with the M-20), and as responsible executive helped Chinese engineers reproduce the machine.
