The paradox of Soviet-style management was that two offices began to do a common business for the country from different ends, pulling the blanket over themselves and categorically unwilling to cooperate (more precisely, only Kisunko wanted to cooperate, all the others tried to shove him off in every possible way).

M-4


For missile defense, obviously, radars (and computers for them) and interceptors (again, with computers for them) were needed. Mints distanced himself from this topic and built radars on Lake Balkhash, which were not related to the Kisunko project - radars of the meter range TsSO-P (later, on its basis, the Dnestr, Dnestr-M and Dnipro radars were created), intended for missile attack warning systems and radar of the decimeter range TsSO-S6, intended for the anti-satellite project weapons Chelomey (the "Taran" system, we have already written about it, the project itself was closed in 1964, but the "Don-2N" radar in the centimeter range grew out of this radar).



Two prototypes of the M4 were installed one piece per complex, and the power for the decimeter radar was no longer enough for the car, and it was necessary to modify it along the way, introducing interface equipment - the so-called. primary processing unit (UPO), in fact a DSP coprocessor.

The upgraded vehicle received the M4-M index.

Kisunko did not get anything from the Ministry of Radio Industry at all - he had to do everything himself, relying on alternative branches of government. Coordinated the work on ABM KB-1 (SKB-30, Ministry of Defense), computers were built by ITMiVT (Academy of Sciences of the USSR), the anti-missile was manufactured in MKB "Fakel" (Ministry of Defense), and there was a gag with the radar - the Ministry of Radio Industry, of course, could not be connected in any way ...

As a result, they turned to NII-37 (NIIDAR), owned by the Ministry of Communications Industry. The interface equipment was handled by TsNIIS and MNIRTI (Academy of Sciences of the USSR). Actually, the entire Sary-Shagan test site was originally ordered by the Ministry of Defense for testing the "A" system, while the Ministry of Radio Industry also rushed to grab a piece of the pie and placed its experimental radars of the early warning and "Taran" projects there.

Kisunko, of course, did not have access to them, he had his own radar RE-2 (later - early warning radars "Danube-2" and "Danube-3"). Before the arrival of the M-40 / M-50 complex, they had to work, registering and processing data on target tracking on their own KB-1 machine - the monstrous Strela.

The first experimental guidance was carried out not yet on the rocket, but on the IS-3, which was dangling above the Earth at that time, and the target designation was manual, at first the satellite was detected using the KT-50 kinetic theodolite, its coordinates were determined and then the radar was guided.

In the first version of the M4, the classical pulse-potential circuit of the assembly of logic elements was used on far from the fastest P-16B transistors, which practically repeats the tube logic elements of the M2 machine in circuitry. Yu. V. Rogachev proposed to remake the serial machine for more modern high-frequency transistors such as P416, 2T301 or P609.

As a result, in 1964, the more advanced M4-2M, almost identical to the M4, but on a more modern element base, went into the series. Until 1969, more than 50 of them were produced, alas, by that time it itself was already hopelessly outdated, the world was already beginning to switch to microprocessors.

The car existed in three modifications, which received the standard in the USSR brain-exploding indices 5E71, 5E72 and 5E73. The first stage of the early warning missile system was also commissioned in 1969, and these machines worked in it for about 30 years.

М4-2М performed operations on real numbers, own arithmetic was used, one digit per sign, 8 - per exponent and 20 - per mantissa. An original feature of the ALU design was that all operations, logical, arithmetic and control, were carried out in one cycle, about 3 cycles required only interruptions. Such a sophisticated scheme made it possible to squeeze out an impressive performance for Soviet cars of those years - about 220 KIPS. With a million K-340A Yuditsky could not be compared, but the M4 was universal, not specialized.

The last machine of the series was released already in 1984 (we do not know what is more here - pride in the architecture excellent by the standards of 1960 or shame that the world was already working with the IBM PC), and the last one was replaced (according to Yu. V. Rogachev, one of the designers and friend of Kartsev) in 2000.

Further, Kartsev was awaited by two failures, which seriously undermined his health and faith in himself.

Inflation


We have already talked about one of them - the M5 project, an economic machine for the State Planning Commission, which cost Brook's place. Many argue that socialism does not know the concept of inflation, in fact, apart from 1991, the USSR experienced two massive levels of price increases after the war, without taking into account the smooth natural growth. The first happened in 1947, when the total money supply in the country was reduced by 3,5 times. Many remember the predatory Pavlovian reform, but Stalin's one was no less predatory.

The resolution of the Council of Ministers said:

Monetary reform requires famous sacrifices. The state takes on most of the victims. But it is necessary that some of the victims were taken over by the population, especially since this will be the last victim.

In fact, it was the population that took the greatest sacrifices. The essence of the reform was that the old banknotes were exchanged for new ones in a ratio of 10: 1 with a constant price scale. There were some exceptions: deposits in savings banks up to 3 thousand rubles were fully preserved, deposits from 3 thousand to 10 thousand rubles were cut by the state by a third, and only half of the amount of 10 thousand rubles was returned.

At the same time, there was a conversion of "eternal" government loans, which no one was ever going to return anyway, they were all combined regardless of the previously promised interest rate and changed to new ones at the rate of 3: 1, and even with a decrease in interest. The reform was being prepared as a secret one, but rumors still leaked to the people.

Moscow engineer Viktor Kondratyev described it this way:

For several days the people on the streets are dark, all the shops - both commercial, commission, and manufactured goods - are covered in queues ... Well, in the evening, commercial restaurants were stormed from the battle, shouts, abuse. And someone just decided to lower the last hundred, because a new life will begin, with new money and without cards, why save old money.

Thanks to the party and government for taking care of the needs of the people.

She wrote Pravda on December 16, 1947.

For a long time, however, there was not enough money, and the second inflation had to be extinguished under Khrushchev in 1961, changing the money in a ratio of 10: 1 one more time.

This was preparation for a large-scale economic reform in 1965, called Kosygin. It was in the midst of the preparation of the reform that the final battle was fought between cybernetic economists and economists of the old formation, such as the author of the reform, Yevsey Grigorievich Lieberman. Doctor of Economics V.D.Belkin, who worked together with I.S.Bruk, who in the last years of his activity became interested in economic problems, in connection with the planned economic reform, tells about this:

Brooke was one of the few who responded to the call for a radical economic reform and to build socialism, if not with a human, then at least with an economic face. But all this at the top was terribly sabotaged. The old monolith was no longer there, but they tried to hold the system. An attempt on her life was seen even in the most innocent proposals of the economists of our institute. Brook clearly understood that the country's economy was going to a dead end, and said that this was facilitated by the insufficient connection between the two systems of government - the Soviet (Council of Ministers, Gosplan, etc.) and along the line of the party.
“The control system that the party has created is a quick response system, but its disadvantage is the lack of feedback,” he said. You need to have the perspicacity of J.S.Brook to say such words then.
... A strong battle took place in the State Planning Committee (on price policy), at which its chairman Lomako, this last official of the Stalinist style, said to Brook: the State Economic Council created at that time under the USSR State Planning Committee. - Author's note), and this revolt will cost you dearly. "
He was simply forced to retire.

As a result, the riot really cost dearly - the INEUM team was partially dispersed, all work on the M-5 was stopped, Brook was fired.

M-9


Kartsev continued to work on the M-9 supercomputer in the INEUM special development department until 1967, commissioned by Kisunko, and presented the car for the competition. We also already know what happened next, after all the twists and turns the project was rejected, and Kisunko did not receive any of the computers - neither the M-9 nor the 5E53.

After the second disappointment, Kartsev moved to the Ministry of Radio Industry, to the NIIVK created under him, hoping that here he would be allowed to develop computers without problems and hindrances.

Note that the M-9 machine, with all its merits, was extremely complex in terms of programming. Recall that in M-9 there were 3 pairs of "processor-mask" blocks that perform operations on vectors and matrices. The first bundle consisted of a matrix of 32x32 16-bit processors (the so-called functional block) and a matrix of 32x32 1-bit processors for operations on mask bits. The second bundle consisted of a vector coprocessor of 32 nodes and the same mask block. Finally, the third bundle consisted of an associative block performing comparison and selection of subarrays by content, and the same mask block for it.

The M-9 was a prototype, it was proposed to assemble production vehicles from a relatively arbitrary set of these blocks, in particular, the M-10 was supposed to consist only of a functional block, and the monstrous M-11 from eight. It all sounded insanely cool, the only problem was how to manage this magnificence.

In any case, a machine of this class, to demonstrate its full computing power, had to work with a perfectly parallel program, which meant either the design of a control block of insane complexity, or writing an insane complexity of an optimizing compiler. Or (if you follow the path of the CUDA architecture and the OCCAM language written for Inmos transputers), it was required to develop a separate parallel programming language, however, there was nothing unsolvable in this task.

The M-9 project was presented by Kartsev in March 1967 at a symposium on computing systems and environments in the Siberian Branch of the USSR Academy of Sciences. The speech of the leading mathematician-programmer E.V. Glivenko on the construction of the software for such a multiprocessor system convinced of its realizability.

Yu.V. Rogachev writes:

Since the leadership of the Ministry of Instrument, which INEUM was part of at that time, resisted the inclusion of this work in the institute's plan, by a government decree, the INEUM special development department was transferred to the Ministry of Radio Industry as Branch No. 1 of OKB Vympel. The team of Branch No. 1 took part in the development of the preliminary design of the Aurora system, which included the sections of the M-9 computer complex as separate books. But the complex project of the Aurora system was rejected, and further work on the M-9 was stopped. The staff of Branch No. 1 did not get involved in further work of OKB Vympel ... He continued close cooperation with the Radio Engineering Institute, where at that time a project was being developed for a continuous continuous field of over-the-horizon detection of space objects.

In 1968, RTI was just beginning to develop a project for the second stage of an early warning system - the Daryal radar, which requires a computing power of at least 5 MIPS (the vaunted BESM-6 produced about 1 MIPS).

M-10


As a result, RTI remembered Kartsev's project, without giving his development to Kisunko, they decided to put it into action themselves.

Despite the formal separation of Kartsev's group into a separate organization, they were not even allocated premises, and employees sat all over Moscow, wherever they could.

Kartsev recalls:

This is not to say that the development of the M-10 was greeted with open arms. We were told, to tell the truth, that we are nuts, that you cannot put together such a pile of metal that it will never work. We have now taught it, so to speak, psychologically, that a large computing machine can consist of so many equipment. Then no one was ready for this. And it was incredibly difficult for us to work: the collective then worked at Sokol-1, in Bolshoy Vlasyevsky Lane (in the basement), in the basement on Burdenko Street, in the basement on Plyushchikha, on Bolshaya Pochtovaya Street, in the basement on Shchukin Street, and more. in several locations throughout Moscow.

Having separated from INEUM, the team received the premises of the former carpentry workshop of one of the enterprises on Sokol with an area of ​​590 sq. M. meters. To accommodate the entire team, they had to search all over Moscow and rent non-residential premises, mostly of a semi-basement type. The institute built its own building (model school) only in 1975, and the laboratory building according to a special project in 1985-1986 after the death of Kartsev.

In general, the leading technical school in the USSR ITMiVT Lebedev (which never in its entire history never quarreled with any authorities and therefore was treated kindly in every possible way) considered, following the position of its founder and guru, multiprocessor and multi-machine complexes evil. Lebedev can be understood, he was terribly worn out with debugging a much simpler BESM-6, due to its wretched element base and the low quality of Soviet components. But Kartsev and Yuditsky were geniuses of a completely different class, they possessed the secrets of assembling reliable computers from unreliable components.

BESM-6 used 60 thousand transistors, 180 thousand semiconductor diodes, 12 million ferrite cores. Computing complex of three computers M-10 contained 2 thousand microcircuits, 100 million transistors and 1,2 million ferrite cores. This is not only a pile of metal, but also an unimaginable number of connections that had to be made to work harmoniously. In the end, everything worked out - the uptime of the M-120 was equal to an unimaginable 10% - a value that characterizes the best IBM mainframes. The downtime of the complex due to malfunctions did not exceed 99,999 minutes a year!

Naturally, Kartsev could not help but make envious people.

Remembers B.N.Malinovsky:

Somewhere in the late 60s or early 70s, Kartsev called me in Kiev and asked me to be an opponent on the doctoral dissertation of an employee of his institute V.A.Brik, a participant in work on VK M-9. Getting acquainted with the dissertation sent to Kiev, I was convinced that it was far from ordinary - completely new methods were proposed for accelerating a number of operations and the corresponding, proven by practice, original circuit solutions. In the thoroughly researched field of science and technology, where, it seemed, everything had already been studied and put in its place, the author of the dissertation was able to say a new and very significant word. The second opponent, a well-known scientist who wrote a number of books on computer technology, A.A. Papernov, was of the same opinion. The speakers also supported the dissertation. We were both shocked by the negative decision of the Academic Council headed by Academician V.S.Semenikhin. It was clearly biased. The members of the council, who were unfriendly towards Kartsev, played out on his student.

It was difficult, but by the middle of 1970 Kartsev submitted a set of documentation for the M-10 to the Zagorsk plant. The car was mastered there only two years later, and the serial copy was released in 1973.

Again, pay attention to the cycle: six years (!) From the development of an idea to the first production car - an inconceivable, monstrous time frame for which everything that could become obsolete became obsolete. Created in 1967, the M-10 (not to mention the M-9) would have become one of the fastest in the world on a fairly modern element base, assembled in 1973 - it was not included in the top twenty, and was also assembled from obsolete scrap metal by world standards. The USSR shamelessly slowed down all innovations: situations when less than 5-7 years passed in the development of computers from idea to implementation can be counted on one hand.

In addition to the computers for the Daryal radar (computer complexes 63I6 and 68I6) and the command post of the early warning system (complex 17L6 of six vehicles), on the basis of the M-10 computer, which received a typical insane (so that evil spies would not understand) cipher 5E66 in the Ministry of Defense, there was a computer complex for the SKKP of General Designer A.I.Savin was created.

In total, by the time production ceased in 1986, about 50 sets of M-10 were produced. Again, the USSR harnessed and accelerated for a long time, but having accelerated, it could no longer slow down. Performance at 5 MIPS was good for the early 70s (the CDC 7600 was 24) and excellent for the 60s, but not bad for the 1982 Cray Y-MP with its 400 MIPS. Actually, by the mid-80s, even the VAX would have more than coped with the tasks of the M-10. Nevertheless, during 1974-1979, until the appearance of "Elbrus-1", the M-10 was the most powerful domestic computer.

Kartsev himself wrote about the performance of the M-10:

The capabilities provided by the M-10 structure cannot always be expressed in operations per second. Therefore, it should not be surprising that, although the performance of the M-10 was at one time estimated at 5,1 million ops / s, the real speed gain in comparison with other machines, when such a comparison was carried out, turned out to be much greater than one would expect. ... For example, when calculating the kinetic model of plasma for a grid of 512 nodes and the number of macroparticles up to 10 to the power of 4 (a variant that fits to the limit in the internal memory of BESM-6), the difference in velocities between M-10 and BESM-6 is approximately 20 times , with a larger number of mesh nodes and macroparticles, it is much more than 20 times; at the same time, on BESM-6, the score went from 48, and on M-10 - with 64 digits. When calculating one of the problems of continuum mechanics, the difference in speeds between M-10 and EC1040 was more than 45 times (8,5 minutes for the M-10 version instead of 6,5 hours for the EC1040).

However, the M-10 was not allowed to work for peaceful purposes - all existing complexes were produced only to service the early warning system. By the way, with the programming of the M-10, the expected problems arose, especially with the stability of the OS.

Major General V.P. Panchenko, who participated in the acceptance of the M-10, recalls:

... it was not possible to achieve stable operation of the new computer complex according to the new program for a long time. Failures occurred every few hours, and failures after 10-15 hours. The situation was heating up. The deadlines for completing the tests passed, but a satisfactory result could not be achieved ...

He is echoed by the designer of the early warning system V.G. Repin:

... this supercomputer of parallel action at that time was good in everything, but still did not meet the reliability requirements, and to a large extent due to the insufficient development of the operating system ... I had to redistribute this work along the way and shift the development of the combat operating system of the computer also the operating system of the multi-machine complex for the SKB-1 programmers.

Note that the M-10 was assembled on the already familiar GIS series 217 "Ambassador" with a maximum frequency of the order of tens of megahertz. The development of the TTL-series 133, ripped off from the TI SN54, was completed at the Zelenograd NIIME in September 1969, and mass production began in 1970, when the documentation for the M-10 had already arrived at the Zagorsk plant. On the basis of the 133 series, in particular, Elbrus-1 was designed.

The ROM for the M-10 was made according to a rather original scheme - capacitor, the firmware was stored on replaceable metal punched cards 265x68 nodes. The punch card was a thin plate 0,5 mm thick with polyethylene insulating pads on both sides. The ROM block could accommodate 128 such punched cards with a capacity of eight 34-bit numbers each. The total capacity of the PC of the machine was 512 KB, the read time was 0,5 μs, and the cycle time was 1,3 μs. The volume of the car turned out to be monstrous - 31 cabinets (!), Of which 21 were occupied by memory cabinets.

In general, the Western school of supercomputers provided for some kind of product design based on optimization. For example, the Cray-1 was shaped like an art deco sofa, not because Seymour Cray was a fan of modern furniture, but because this shape facilitated the shortest signal path and optimal cooling. Nevertheless, a machine with a capacity of 30 M-10 fit into a volume of about 2 cubic meters (not counting the power and cooling systems, in both cases they occupied an entire hall), the USSR could not afford such delights due to the monstrous element base - with thin-film GIS you won't go too far, it's good that all the closets fit into at least one room.

OS M-10, which was finally assembled, worked in a time-sharing mode with 8 independent terminals. The most advanced version of the OS allowed connecting up to 48 terminals with output to an EC7064 interactive display with a keyboard and light pen. Programming was carried out in assembler M-10, ALGOL 60 and FORTRAN.

In general, such programming problems are not surprising: neither ALGOL and FORTRAN were parallelizable (from the word - at all), in the West they created their own languages ​​for such architectures, such as OCCAM, so one can only imagine how they were tormented with the M-10 who tried to adapt the unadjustable to it.

The M-10 contained software debugging hardware, which was incredibly cool at the time.

M.A.Kartsev describes this feature of the technique as follows:

The directives interpreted by the specified equipment include starting, stopping, continuing the program being debugged, passing through individual sections of the program in steps, outputting the contents of various registers, individual cells or memory arrays to the terminal, entering information from the terminal into registers or memory, managing a register, etc. a pattern of coincidences. The case and match scheme are very important tools for debugging programs. They make it possible, according to the directives transmitted by the programmer from the terminal, but without making any changes to the program being debugged, to set very complex conditions for generating an interrupt signal, according to which the program stops or control is transferred to any debug program written by the programmer in free memory space.

As a result, the M-10 could perform a halt under rather complex conditions such as "interruption if control was transferred to cells with numbers from such and such to such and such" or "if such and such address modifier register "and so on. Not Burroughs, of course, but by the standards of Soviet cars, an unrealistic level of technology. The range of actions in response to an interrupt was also huge - from trivial printing a memory dump, to displaying the internal clock or manually overwriting some registers.

What is funny, Kartsev himself perfectly understood all the squalor of the imperative languages ​​of the 1960s as applied to parallel programming and suggested that all programmers write directly and decisively in the M-10 assembler:

Since performance and efficiency were considered the main goals in the design of the machine, from the very beginning it was assumed that programming would be carried out mainly in machine-oriented languages ​​Autocode-1 M-10 (in fact, just a one-to-one symbolic language, however, with good mnemonics) and Assembler - a language of a slightly higher level. Translators from Algol-60 and Fortran into the M-10 language appeared later, however, and until now, despite numerous improvements, their use leads to significant performance losses in comparison with programming in machine-oriented languages, because the structure of M- 10 and, in particular, its machine language is very different from the structure to which modern algorithmic languages ​​are oriented (although they are called problem-oriented or even universal) ... It is possible that the initial premise that system programmers , and users have to work mainly with machine-oriented languages, was wrong.

Payment from M-10 and GIS "Ambassador" from Rogachev's book

In general, the unfortunate Kartsev directly recommended throwing out Fortrans and Algols if it was necessary to squeeze out more performance from his machine than from a toaster, and write everything with his hands in machine codes.

The problem that we mentioned - a super-complex UU or a super-complex compiler - was solved in the USSR in a non-trivial way - by super-complicated manual writing of programs in a low-level language. For some reason, no one thought to develop for M-10 a high-level language and programming environment of a healthy person corresponding to it in terms of power and convenience.


Abandoned radar early warning system Daryal-U receiver, Balkhash-9, station location map, station reference plan (https://swalker.org/, https://ru.wikipedia.org)

In 1977, the M-10 was modernized, mainly at the expense of memory, it was possible to push 21 cabinets into 4 double ones. The M-10M became the first computer that NIIVK received at its own disposal, having created a multi-user simulation stand on its basis. This stand, in particular, designed multilayer printed circuit boards for the new M-13 machine, the development of which began in 1977. It was on this machine that the calculations of plasma physics, which were cited above, and many other scientific works were carried out.

Comparison with the "Elbrus" in the M-10 also happened, and the results were interesting. B. Andreev from the Leningrad Design Bureau, who worked with both systems and debugged both machines, was quite competent in comparing them:

All the wretchedness and carelessness of the Elbrus-1 MVK especially contrasted in comparison with the M-10 computer of MA Kartsev, which was located 50 meters away at our enterprise. This, by the way, was the only place in the USSR where both Soviet supercomputers stood side by side and could be compared by us.

As we have already said, ITMiVT was a rather specific place and developed quite specific machines in it, which became legendary not because of their unique consumer qualities, but because of Lebedev's charisma and his ideal image in the eyes of the Central Committee of the CPSU.

As a result, in the USSR, only one series of machines was officially mythologized, cast, in the words of the greats, in granite and declared the gold standard - BESM and everything that was created on its basis (well, Elbrus, as a grandchild second cousin along the Burtsev line). All other developments were considered either secret or marginal, or did not go into series, or did not receive even one tenth of such honors.

For the Don-2N-level radar, more powerful computing means were required (as a result, they cost four 10-processor Elbrus-2 per station, each with a capacity of 125 MIPS, totaling about 500 MIPS, which corresponds to approximately a modern 7nm HiSilicon Kirin 980 tablet) , and Kartsev finally decided to build the greatest supercomputer.

M-13


The M-13 computer project envisaged a series of machines based on three basic models of increasing power. At the same time, the small model (M-13/10) differs from the medium (M-13/20) and large (M-13/30) quantitatively - the completeness of memory devices, additional external devices, etc., on which the performance depends.

The central processing unit has three configurations and can provide performance depending on the version - 12, 24 or 48 MIPS, RAM - 8, 5, 17 or 34 MB, the bandwidth of the central switch - 0,800; 1,6 or 3,2 GB / s (which is cool even by modern standards!), The throughput of the multiplex channel is 40, 70 or 100 MB / s.

The M-13 also included Kartsev's proprietary processor, designed to work with highly sparse data. Its equivalent performance reached 2,4 GIPS.

In general, the M-13 was a further development of the same original ideas embodied in the M-9 layout, and it is insanely annoying that this unique architecture did not receive its embodiment back in 1967.

The M-13 was built on the same TTL logic of the 133, 130 and 530 series as the first Elbrus, and many domestic military computers of the 1980s, including the on-board computer of the S-300 complex, which we will also talk about separately.

Kartsev disliked powerful ECL logic, which was not surprising - the problems with the Soviet clones of Motorola MC10000 became legendary, the yield of suitable microcircuits was measured at the beginning almost in units, the developers of Elbrus-2 and Electronics SS BIS tormented them mercilessly, up to the fact that Burtsev was forced to personally travel to the plant and sort out batches of chips with his hands in search of more or less efficient ones.

The emitter-connected logic of high integration made extremely stringent requirements not only to the quality of manufacture, but also to the installation of components, power supply and cooling, which also came back to haunt the developers of these systems more than once.

In 1981, Kartsev recruits the finally broken and tired Yuditsky, saving an old friend from the need to work as some kind of TV repairman, but for Yuditsky it is too late.

He no longer takes part in the development and in 1983 he dies at the age of 53. This was a blow for Kartsev, superimposed on no less unpleasant events.

Let us give the floor to his colleague and deputy Yu.V. Rogachev, who later wrote a book about these sad events:

By the end of 1982, OZ NIIDAR manufactured and supplied the institute with a fully equipped with cells and blocks OPP device, as well as 9 cabinets and a number of blocks with cells of other devices. All this showed that the design documentation provided all stages of manufacturing and did not cause any fundamental difficulties. And in February 1983, when the OPP device successfully passed the tests according to technical conditions, it became clear that there would be no special difficulties with setting up the devices.
However, neither the results of the work of the Pilot Plant, nor the approaching delivery time for the M-13 computer to the facility for the Daryal-U radar station forced the heads of the DMZ and YURZ to start manufacturing the machine. Failed to force these factories to start production of the M-13 computer and the leadership of the CNPO "Vympel". In an effort to somehow justify their impotence, the leadership of the Association decided to recoup the developers of the machine, announcing in March 1983 at the balance committee the work of NIIVK was unsatisfactory. Moreover, this was expressed in an incorrect form, without specifying the reasons and specific facts explaining such a decision. Deputy General Director V. V. Sychev behaved especially dishonestly in this matter. Just a few days before the balance commission, getting acquainted with the results of tests according to the technical specifications of the OPP device of the experimental model of the M-13 computer, he gave a positive assessment of the work of the institute both on the M-13 machine and on the 63I6 computer complex as part of the Daryal radar, on which at this time the State tests were being completed. And it was V.V.Sychev who at the balance commission announced a negative assessment of the work of NIIVK.
MA Kartsev, an extremely decent and intelligent man, was shocked by such hypocrisy. He immediately told the general director of the Vympel TsNPO Yu. N. Aksenov that he would not be able to continue working under such leadership. The feeling of injustice in relation to the NIIVK team was an additional burden on the heart and greatly affected the health of M.A.Kartsev. He was greatly worried about the situation with the launch of serial samples of the M-13 computer at the Vympel TsNPO plants: the behavior of the Association's leadership did not promise anything positive in this direction.
Did not clarify the issue with the manufacture of the machine and the meeting on the progress of work on the creation of the radar "Daryal-U", which in mid-April was held at the Radio Engineering Institute by Deputy Minister of Radio Industry OA Losev. They spoke about the difficulties in the production of the station's equipment, especially the difficult situation with the manufacture of the M-13 computer was emphasized. However, our proposal to abandon ambitions and ask the Minister to connect the Zagorsk Electromechanical Plant to the production of M-13 was rejected. At the same time, the directors of the CNPO Vympel factories did not give firm promises to start manufacturing the machine.
Strange at this meeting was the speech of Vympel technologist V. G. Kurbakov, who did not talk about manufacturing technology, but criticized the technical solutions of the chief designer on the architecture of the machine, questioning the operability and operational characteristics of the M-13 computer. Who needed to adjust this presentation, how a person who had absolutely no knowledge of computer technology could make such a statement at a meeting of this level, remained a mystery. Except for the chief designer of the Daryal-U radar AA Vasiliev, who called this speech far-fetched and untrue, no one stopped the presumptuous "specialist" - neither the leadership of the Association, nor the deputy minister. This was already the last straw that overflowed the cup of patience: MA Kartsev announced to OA Losev about his firm decision to raise before the Minister of Radio Industry PS Pleshakov the issue of transferring NIIVK from TsNPO Vympel to the 8th GU MRP.
In the order of preliminary agreement on this issue, on April 19, 1983, M.A.Kartsev invited to the institute the Deputy Minister of the Radio Industry N.V. Gorshkov, who supervises computer technology in the MRP, the chief engineer of the 8th State University, which was in charge of scientific and industrial enterprises of computer technology, in including the Zagorsk Electromechanical Plant. MA Kartsev acquainted them with the M-13 computer - its design, element base, manufacturing technology and the course of setting up experimental devices. In the conversation that followed, Mikhail Aleksandrovich asked to support his proposal to transfer NIIVK to the 8th Main Directorate of MRP and transfer the manufacture of the M-13 computer to the Zagorsk Electromechanical Plant. Consent was obtained.

However, this did not save Kartsev.

The failure of the M-5 and M-9 projects, the death of Yuditsky, the monstrous intrigues with the adoption of the M-13 finally undermined his health. Already before that, he had already experienced a massive heart attack. On April 23, 1983, he was driving his car along Leningradsky Prospekt and suddenly felt unwell. At the Sokol metro station, he parked with all his strength, lost consciousness and died right in the car.

So the path of one of the world's most outstanding computer designers was cut short.

Shortly before that, Kartsev finished his speech on the fifteenth anniversary of the institute as follows:

... It seems to us now that we have never released such a good development as we are trying to release now, and that it has never been so difficult to release a development as it is now, we have never encountered such difficulties. But I just want to remind you that we experienced another fall in love with each of our developments, and we always had incredible difficulties. Now I wake up at night in a cold sweat from the fact that the production of our new brainchild is proceeding so slowly and with such difficulty. But, you see, this, in general, refers simply, probably, to senile insomnia. But in fact, not very much has passed since the day we received the government's order, only two years and eight months have passed. And it cannot be that our team, which includes both white-haired and experienced veterans, and energetic and educated youth, so that we do not pull out this offspring of ours!

The development team fought like a lion with the party bureaucrats and officials of Vympel for the release of the car of their teacher and friend.

Rogachev recalls:

On May 5, 1983, Deputy Minister OA Losev decided to discuss with the leadership of the CNPO Vympel the issue of the situation in NIIVK. I was also invited to this meeting. The management of the Association prepared for discussion two versions of draft orders on the further activities of the institute, which significantly changed its status. The first option completely deprived the institute of independence, including its staff in the STC TsNPO "Vympel". I categorically rejected this option. The second option, on the contrary, included the STC in the NIIVK, which, in essence, meant the same thing, only with the preservation of the name, since the subject of the STC became a priority. It was clear that the subject matter of NIIVK would move to the background, and the name change was just a matter of time.
The discussion of these projects was interrupted by a telephone call from the minister. PS Pleshakov asked OA Losev to come to him to resolve the issue of NIIVK, informing him that he had N.V. Gorshkov with this issue. (This means that our draft order was presented to P.S. Pleshakov). After a while, we were invited to the minister as well. NV Gorshkov was no longer in the minister's office. Addressing me, Petr Stepanovich said that the leadership of the Ministry appoints me as the director of NIIVK, and the institute retains its existing status and position. This meant that our proposals on the transition to the 8th GU were not accepted, but the proposals of the Central Scientific and Production Association "Vympel" were not accepted either.
And yet, after a while, the question of transferring NIIVK to the 8th GU arose again. At a meeting of the collegium of the Ministry of Radio Industry in October 1983, when discussing the progress of work on the creation of the Daryal-U radar station, I managed to convince the members of the collegium that the CNPO Vympel factories would not master the serial production of the M-13 computer, at least in the coming years. will be able to. Only ZEMZ can save the situation. After a long and heated discussion, the board made a decision on the production of the machine at the Zagorsk Electromechanical Plant and on the transfer of NIIVK to the 8th GU MRP.
However, the implementation of this decision was hampered by some leaders of the Vympel CSPO. In particular, the deputy general director V.V.Sychev tried by various methods, including pressure on the leaders of party and public organizations, on the scientific activists of NIIVK, to force the leadership of the institute to abandon the decision to withdraw from the Association. And only the intervention of the deputy head of the defense department of the Central Committee of the CPSU V.I. Shimko put an end to the red tape with the transfer of NIIVK to the 8th GU MRP. This translation was completed at the end of November 1983.
... The management of the plant refused to use the FOSs previously manufactured at the Vympel CNPO, and decided to make a new set directly on its equipment to guarantee the quality of the MPP. So simply the issue was resolved, which was a stumbling block in TsNPO "Vympel" and kept the institute, and the design bureau of plants, and the management of the Association in tension for two years. In January 1984, ZEMZ received practically all the design documentation required to launch the M-13 computer into production. And by the middle of 1986, NIIVK received all the prototype devices manufactured with the customer's acceptance. Complex docking of the machine as a whole began, and by the end of 1987 the head model of the M-13 computer had successfully passed the factory tests.


Genealogy of Brook and Kartsev's machines, drawing by Yu.V. Rogachev


The only civilian development of NIIVK after the death of Kartsev is the famous personal computer "Agat-7" on the clone of the MOS 6205 processor, the clone of Apple I, the first PC in the USSR, released in 1984. By 1989, a clone of the Apple II, Agat-9, had been developed. (https://www.computer-museum.ru)

The absolutely typical schizophrenic bureaucracy of the USSR led to the fact that the release of the M-13 was postponed for FOUR years - from 1983 to 1987 there were continuous battles in the spirit of the Kafkian absurdity, questions of subordination and subordination were resolved, and officials tried to share potential awards (if successful) and find who to blame in case of failure.

As a result, the first pilot series of M-13 entered the Daryal-U facility in 1988, with its installation, debugging and acceptance, it took another three years, and only in 1991 the M-13 passed state acceptance. In total, twice as much time was spent on the introduction of the machine as on its construction - eight years! Crazy, unimaginable deadlines by the standards of any country except the USSR. Naturally, by that time an excellent machine by the standards of 1979-1980 had turned into a pumpkin, literally a couple of years later microprocessors of comparable power appeared ...

Vladimir Mikhailovich Kartsev recalled his father like this:

Father did not like unprofessionalism in any area. I remember the words of indignation when he assembled a receiver from a children's kit, in which not a single part could fit in the place allotted to it. ... The father's intellect remained in his designs and books, the works of his followers, intelligence - only in the memory of those who knew him. The latter quality made the father more vulnerable in those cases when it was necessary to agree with the powers that be or demand something. Without intelligence, as well as without a sense of humor, there would not be that person whom we all remember.

It is obvious that such people were not as adapted as possible to work in the USSR system.

So, at the end of the cycle, we just have to consider the only scientific school that supplied serial computers for all types of air defense and missile defense - from S-300 to A-135, the great and terrible ITMiVT and its machines, after which we will collect all the pieces of the puzzle and will ready to answer the final question about the development and fate of the national missile defense.

      The essence of the reform was that the old banknotes were exchanged for new ones in a ratio of 10: 1 with a constant price scale.

      Let the author explain why the price tags on books published before 1947 remained the same as on books published from 1947 to 1961, but after 1981 they were charged with a change in the price scale.

    There are such considerations about G. Kisunko. In 2017, the publishing house "Algorithm" published his memoirs "Anti-missile shield over Moscow". Judging by the content, the author wrote them in the late 80s. There, he was extremely skeptical about the single-channel S-75, and he did not like the S-200 either, three quarters of the book describe how he fought with Raspletin and Kalmykov, naturally, as it should be in his memoirs, his proposals were the most correct. So it's not worth appealing to his biased opinion.

    The volume of the car turned out to be monstrous - 31 cabinets (!), Of which 21 were occupied by memory cabinets.


    The factor of psychology is not taken into account. For managers making decisions on missile defense, these volumes do not at all seem to be something particularly large - they make decisions about the construction of a much more significant infrastructure, such as an aircraft plant or an airfield (and here, from their point of view, some insignificant lockers are considered, as in a sports dressing room ). Moreover, the leaders of those times and at that level of technology. That is, the priority was given to the performance of functional tasks and not the secondary mass-dimensional characteristics of a stationary, in fact, installation. Therefore, it is more correct to criticize the quality of radio-electronic components and not, in general, the priorities of the leadership that were correct for that time - the days of iPhones had not yet come, unlike the era of intercontinental missiles.

    the USSR standard brain-exploding indices 5E71, 5E72 and 5E73.

    typical insane (so that evil spies do not understand) code 5E66

    I wonder why these "ciphers" tear the author's brain?
    The GRAU indices have a completely understandable and logical structure: the first number identifies belonging to a certain class of weapons and equipment ("5" is missile defense), the letter "E" identifies the product as an automated combat control system, the subsequent numbers - the item's position in the corresponding section of the timesheet.
    But each ministry invents design and production codes according to its own rules, and in them, indeed, the devil will break his leg.

    The essence of the whole story with super and not so computers boils down to the fact that the progress in data processing is enormous and in one not the coolest phone or tablet today, the processor performance is hundreds and thousands of times higher than the super computers of past years, but all large and brilliant developments , especially in the military sphere, fall on the 30-70s of the last century. Apparently, the essence of a technological breakthrough is not in gigaflops and petabytes, but in a creative approach to tasks and an easy dose of fantasy and dreams, multiplied by the classic Soviet and Western (each in its own way) engineering education.

    Comparison with the "Elbrus" in the M-10 also happened, and the results were interesting. B. Andreev from the Leningrad Design Bureau, who worked with both systems and debugged both machines, was quite competent in comparing them:

    All the wretchedness and carelessness of the Elbrus-1 MVK especially contrasted in comparison with the M-10 computer of MA Kartsev, which was located 50 meters away at our enterprise. This, by the way, was the only place in the USSR where both Soviet supercomputers stood side by side and could be compared by us.

    By the end of 1982, OZ NIIDAR manufactured and supplied the institute with a fully equipped with cells and blocks OPP device, as well as 9 cabinets and a number of blocks with cells of other devices. All this showed that the design documentation provided all stages of manufacturing and did not cause any fundamental difficulties. And in February 1983, when the OPP device successfully passed the tests according to technical conditions, it became clear that there would be no special difficulties with setting up the devices.
    However, neither the results of the work of the Pilot Plant, nor the approaching delivery date for the M-13 computer to the facility for the Daryal-U radar station forced the heads of the DMZ and YURZ to start manufacturing the machine. Failed to force these factories to start production of the M-13 computer and the leadership of the CNPO "Vympel".
    ====
    A few words - OZ NIIDAR is a pilot plant NIIDAR near the metro station Preobrazhenskaya Square - now it is being demolished (all buildings are dark in the evenings). I worked there from 1981 to 1994. And they did the sections for Darial. We went to Balkhash. All the described rehearsals are not for us, we are in the workshop - at the end of the block we used to stay overnight to hand over the section.

    Yes, what a charm - a story about outstanding Soviet computers and their developers from an anti-Soviet. To the credit of the author, he sometimes finds warm words for our computers, and not just dry statements or ridicule. At the same time, while criticizing, he himself makes many controversial statements.

    Comparing the Soviet M10 with the American Cray 1, he complains that ours is on some old GIS, and the American one is on real microcircuits. And why be surprised - the M10 has been developed, as far as the author’s reasoning can be understood, since 1967 or even earlier, when more or less complex ICs with a low degree of integration were just appearing, and Cray-1 began to be developed in 1972, when there was tremendous progress in microelectronics - a variety of LSIs, the first microprocessors, memory chips, etc., have already been created. At the same time, speaking about the timing of the introduction of the M10, they are called "monstrous" - as much as 6 years from the start of creation to the release of the first machine (moreover, the release was delayed due to the fault of the manufacturing plant, and quite possibly, it was agreed with the timing of the release of other components of the early warning system), but and Cray-1 was not created in a year - 4 years from the start of development to the delivery of the first copy (and the second was delivered a year later, in 1977).

    Another subject of the author's "ridicule" is the long years of production of some models of Soviet computers. It seems to be obvious madness and an indicator of "backwardness" - to make the same computer for 15-20 years (though usually with a gradual modernization of the element base). But the fact is that a number of American computers were produced for about the same amount, or even longer. For example, the famous gaming Commodore 64 has been produced for 12 years with virtually no changes, the Atari 400/800/XL/XE gaming series for 13 years, the "innovative" Apple company has been releasing its Apple II (with minor upgrades) for 16 years already. And the famous DEC produced computers of the PDP-11 series for about 25 years! Shame on Americans? :)

    Another interesting point is the comparison of computer performance. There is a lot of incomprehensible here: the author writes that the performance of the M10 is only 5 million op / s - only 5 times more than the BESM-6 and approximately the same as that of the "regular" VAX (actually, these were also not the simplest and cheapest machines - after all, they were called super-mini-computers, and 5 MIPS is the performance of older VAX models, and they appeared only in the late 1970s), then he quotes that the M10 was 20 or more times faster on complex tasks, than BESM-6. And here we must be aware that the performance of BESM-6, despite the seemingly modest figure of 1 million op / s, was very serious - judging by the tests, personal computers surpassed the performance of BESM-6 (developed in the mid-60s - x and made on conventional transistors and diodes) only by the end of the 1980s, only after the appearance of rather cool 32-bit processors of the 80386 and 68020 level. In reality, judging by the tests, the BESM-6 is comparable in speed to the VAX-11 , and the M10 is close to mid-1990s Pentium processors. The author writes that Cray-1 was 30 times faster than our M10. This, to put it mildly, is very debatable - according to the available tests, Cray is faster than VAX-11/780 by about 15-20 times, and Wax, as already mentioned, is very close to BESM-6, and M10, according to its developers, in a number of real tasks faster than Besm by more than 20 times. That is, it is possible that the M10 and Cray-1 were quite comparable in terms of real performance, although, of course, it depends on the type of tasks being solved.

    Well, a number of the author's statements make me smile personally - for example, shame for the release of computers 1984 years ago in 20, when the world was already using the IBM PC. The fact is that the first models of these same IBM PCs were not at all some outstanding PCs - they did not particularly stand out either in speed, or in graphic or sound capabilities, the architecture was almost 8-bit, they did not have any revolutionary functions (such as a graphical interface OS on Apple PCs Lisa and Macintosh), and at the same time they were very expensive ($ 1565 in 1981 with 16 KB RAM and without peripherals - this is actually several times more expensive than home PCs popular at that time with similar capabilities). Then, in 1984, the first fairly decent model of this series just appeared - IBM PC / AT, with 16-bit designs, good processor speed, a decent video card, but too expensive for mass use - from $ 5000.
    And before that, IBM PCs were not some particularly massive and widespread PCs - they began to play a more or less noticeable role only in 1983 (their first clones appeared at the same time), and the dominant position was taken by the "IBM-compatible" family only by the end of the 1980s, and precisely due to the widespread production of a huge number of clones, including quite cheap ones. So in 1984, and much
    later, the world also used rather toy or semi-toy TRS-80, Commodore 64, Apple II and clones, Atari, ZX Spectrum, MSX, Amstrad CPC, TI-99 / 4A, etc., or analogues of the simplest IBM PC type XT.

    Another funny trifle - in the caption under the photo of the Soviet PC "Agat" for some reason it is stated that Agat-7 was an Apple I clone (and Agat-9 was an Apple II clone). If the second can still be understood (Agat-9, of course, is not a "clone" of Apple 2, but, to be more precise, it has a software compatibility mode with it, but is also compatible with previous Agat models that had, for example, their own video modes that had nothing to do with to the Apple II). But where Apple I is simply incomprehensible - these were not even computers, but amateur radio boards developed by Wozniak for self-assembly of computers by enthusiasts (and sold precisely as a separate board, without a case, power supply, keyboard, etc.). Only a few hundred of these boards were manufactured at the very initial stage of the existence of the Apple microfirm (there were only a few employees at that time), until they finally found funding and began to produce a full-fledged Apple II PC (not compatible, by the way, with Apple I) . At the same time, the Apple I boards did not differ in anything outstanding - this is an ordinary, simplest computer based on 6502, with 4 KB RAM, with a black-and-white text video controller, and even without an interface for a tape recorder (for some reason, Wozniak did not add it to the board - it was supposed to connect tape recorder controller as a separate module). Agata-7 has nothing in common, and this is a very serious PC that had RAM up to 64 KB or more, pseudo-ROM, different graphics modes, up to 16 colors, built-in drives, etc., and there was no Apple I, except for the same 6502 microprocessor.
