The Engineering Heritage of Bashir Rameev at the Polytechnic Museum: Honoring the 100th Anniversary of His Birth

. Bashir Iskandarovich Rameev fulfilled one of the main roles in the informatization of Russia as the developer of Ural computer. In English publications, information about him and his contribution to science is practically absent. Nevertheless, he left a valuable legacy in the form of his developments of the family of universal automatic digital computing machines “Ural” with advanced software. The engineering heritage of B. I. Rameev is kept at the Polytechnic Museum in Moscow. The tube automatic digital machine “Ural-1” takes a special place in the computer collection at the Museum. The personal documentary collection of B.I. Rameev is voluminous and unique in its content. The documents of his collection reflect the entire history of the creation and development of domestic electronic computing machines. Among these documents the project “Au-tomatic Digital Computing Machine” of I. S. Brook and B. I. Rameev and patent No 10475 (USSR author’s certificate) on 4 December 1948 are preserved. This patent was the first officially registered invention in the field of electronic digital computers in the USSR. On the suggestion of the Polytechnic Museum, 4 of December 1948 is considered (not yet officially) to be the birthday of Russian in-formatics. It is impossible to overestimate the contribution of B. I. Rameev to domestic electronic computing equipment. His name should be preserved in the history of Russia.


Introduction
In the Soviet Union, the engineer and chief designer of the computer family "Ural" В. I. Rameev together with scientists such as academicians S. A. Lebedev and V. M. Glushkov, corresponding members A. A. Lyapunov and I. S. Brook stood at the origins of the creation of domestic electronic computers.The merits of Lebedev, Glushkov and Lyapunov were recognized by the international scientific community.They received the rank "Computer Pioneer" from the IEEE Computer Society.These scientists created their computers in the system of academic science; they themselves took part in international conferences.Therefore, their names are better known abroad.For example, only the computers of Academician Lebedev are mentioned in the dissertation of Peter Wolcott "Soviet advanced technology: The case of high-performance computing" [1].Furthermore, Wolcott  Likewise, almost nothing is known about Brook's computers and the computers developed in SDB-245 in the international literature.Alex Bochannek, a researcher of the Computer History Museum in California, showed in his paper [2] that information about general computing work done in the Soviet Union was available in unclassified environments.The merits of Brook and Rameev in this area are almost unknown abroad, while they are not less significant.Rameev is one of the founders of electronic computers in the Soviet Union.The merits of Rameev in the field of creating digital computers are recognized by all domestic scientific schools unconditionally.Representatives of various organizations that created computers in the Soviet Union regularly meet in the Virtual Computer Museum [3] and all they agreed that Rameev's contribution to domestic electronic computing was significant.
An attempt to present Rameev's contribution to the creation of computers in Eastern Europe is done in this article.The collections of the Polytechnic Museum can serve as sources for further research by historians of computer technology [4, 5, 6,].
As known, at the turn of the 1950s the development of the first electronic computers was conducted in the USA, England, Germany and France.Since the machines were developed mainly for military purposes, the publications on them were very terse.Most machines were built on electromechanical relays, not electronic tubes.Rameev received his knowledge of electronics working at the Institute of Electronics No 108, and also he was fond of radio amateurs.Once he heard the BBC broadcasts that the electronic computer ENIAC was produced in the USA [7], interest in this new technology led Rameev to correspond with academy member I. Brook.Brook was interested in computing and was engaged in the development of analog computers already before the second World War.He was happy to find such an able assistant.In May 1948, Rameev received a position as computer engineer in the Laboratory of Electrical Systems at the Power Engineering Institute of USSR Academy of Sciences.
In the collection of Polytechnic Museum in Moscow, electronic digital computing machines of domestic production from the 1950s to 1990s are presented together with the developments of leading scientific schools, research institutes and plants, that created them.This collection is the only one in the whole territory of the former Soviet Union.All the exhibits that make up the collection are unique: from the operative memory device on the cathode-ray tubes of the first domestic serial computer "Strela" to the onboard computer complex "Argon-16," which controlled flights of space vehicles.The tube computer "Ural-1" is given a special place in the collection (Fig. 1).Its chief constructor was B.I. Rameev (Fig. 2).

B. Rameev's Engineering Heritage
The primary source of B. Rameev's biography and the description of his contribution to electronic computer technics is B. N. Malinovsky's book The History of Computer Science in Persons, published in 1995 [7].The chapter "The son of an epoch" of this book was written by Malinovsky in many respects thanks to the materials that Rameev himself gave him.Later, there were memories about Rameev of other people who knew and worked with him.Margarita Badrutdinova, director of the museum of the Kazan's Electronic Computers Plant, not only carried out scientific research on the roots of Bashir Iskandarovich Rameev concerning his father and grandfather, but also compiled a list of his inventions ( given in Appendix 5.1) [8, 9,].Rameev's companion on the "Ural" family of computers, Gennady Smirnov, made a unique contribution to the description, study and preservation of Rameev's legacy.He wrote several books about the school of construction of Rameev [10, 11,] and compiled a bibliographic index The Computer "Ural" in the World of Publications and Documents 1945-1972 [12].The biography of Rameev in English is given in [13, 14,].Also, according to Rameev's biography and his heritage in the Polytechnic Museum in Moscow, one can trace the entire history of the development of electronic computers in the Soviet Union.Almost all his conscious life since 1948 he created electronic computers, and he one of the pioneers was in this area.Rameev was an active developer of the very first computers in the Soviet Union: the first serial domestic computer "Strela" and the Small automatic digital computer "Ural-1."

2.1
The First Domestic Serial Electronic Computer, "Strela" In 1953, the experimental model of "Strela" was tested by a state commission and recommended for serial production.In fact, the seven computers were not absolutely identical because some corrections were always implemented in each following piece after testing the previous one.They were placed in the Applied Mathematics Institute of USSR Science Academy (USSR SA), the Computing Center of USSR SA and computer centers of some ministries.They were used mainly in tasks related to nuclear power and space research.In 1954 Rameev and other collaborators of "Strela" team were awarded the USSR State Bounty.The exposition of Polytechnic Museum devoted to B. I. Rameev, Yu.Ya.Bazilevskiyi, SDB-245 and the Electronic Computer "Strela" are shown in Fig. 6.
In 1955, Rameev moved to Penza with a group of talented young specialists from SDB-245.In Penza, Rameev became chief engineer of the Penza branch of SDB-245, and then deputy director for research at the Penza Scientific Research Institute of Controlling Computing Machines, later called Research Institute of Mathematical Machines.In Penza, Rameev created his own computer science school.Many leading computer designers began their activity in the Penza school: V. V. Przhialkovsky, V. Ya.Pikhtin and others from the Minsk branch like V. V. Rezanov Severodonetsk [11].There, he worked on the construction of the The Small Automatic Universal Electronic Computer "Ural-1".

2.2
The Small Automatic Universal Electronic Computer "Ural-1" In the years 1930 -1940, USA, Great Britain, France and Germany imposed restrictions on the supply of a number of goods on the Soviet Union.In 1949, the Coordinating Committee on Multilateral Export Control (CoCom) was established by these countries to impose an embargo on the supply of goods to Comecon countries.So the development of the first computers was carried out in isolation from the developments that were carried out in western countries, that actually established a regime of secrecy for the exchange of scientific and technical information.. 1 According to Academician S. Lebedev, the available foreign publications that were received in those years in the USSR were of an "advertising nature."It should be recognized that, unfortunately, later foreign publications to many Soviet specialists remained unknown.In addition, the publications of Soviet specialists were very rare.The exchange of experience occurred with the US was mainly at the level of personal meetings and visits to enterprises [10].In October 1955, in Darmstadt (Germany) S. Lebedev and Yu.Ya.Bazilevsky presented BESM-1 as the fastest computer in Europe with RAM consisting of potentialoscopes, special cathode ray tubes.Furthermore, they presented on the Small Automatic Universal Computing Machine "Ural-1" and on mastering the serial production which had already begun [15] (see Appendix 5.1 for a technical description of the Ural-1 computer).In 1956, Rameev presented the report "Universal Automatic Digital Computer of the type Ural" at the conference "Ways of Development of Soviet Computing Engineering" [16] in Moscow.This was the first scientific conference in the Soviet Union on this subject.One of the first samples of the "Ural-1" computer was used mainly for training specialists at the Computing Center of the USSR Sciences Academy.Since 1957, these machines have been supplied to computer centers, research institutions, military schools and other organizations.At the same time, the Computing Center of the Baikonur Cosmodrome was created on the basis of the Ural-1 computer.
By the early 1960s, "the Ural-1" computer was the most widespread machine in the USSR; it was operated in 128 cities.More than 30 machines operated abroad in 25 countries: in the GDR, Bulgaria, Hungary, Czechoslovakia, Norway, Turkey, England, Egypt and many more.Differently from bigger machines and chiefly used by large computer centers, Ural-1 was the first computer to be widely implemented by relatively small enterprises [10].
Despite the very low speed of 100 operations per second, especially by today's standards, the research and training institutes of the country were lining up behind this machine.For many years, the "Urals" had become the main "labor force" in our computer centers.It also became a "primary school" for numerous constructors, mathematicians-programmers and maintenance specialists.
"Ural-1" was followed by universal computers with the same electron valves-based circuitry, mainly used for civil purposes: "Ural-2" (1959), "Ural-3," "Ural-4" (1961) with ferrite cores RAM and extended ROM on magnetic drums (8x8 K words) and magnetic tapes (12x260 K words).Besides universal computers, "Ural" Rameev produced several special machines: "Weather" for meteorological calculations, "Granite" for probability characteristics of the experimental data arrays, "Crystal" for crystal structure X-ray analysis, a special computer for (geographic) bearings defined from radio detection data, etc.
In 1968, Rameev moved to Moscow and went to work at the Scientific-Research Center of Electronic Computer Technology to engage in a promising project: the Uni-1 See Leslie, "From CoCom to Dot-com," and Schmidt, "Socialist Life of a U.S. Army Computer," this volume.
fied Computer System.He negotiated with the English firm ICL on scientific and technical cooperation in the field of computer production.Documents on cooperation between the State Committee of the USSR on Science and Technology, the Ministry of Radio Industry of the USSR and the English firm ICL are indicating this.They are presented in the documentary collection of Rameev in the Polytechnic Museum [17].Also, in this collection there are documents on Soviet-American cooperation 1972 -1974 in the field of computer application in management within the framework of the Meetings between the Governments of the USSR and the USA on cooperation in the field of science and technology.These are work plans and reports of a mixed Soviet-American group.Rameev also took an active part in the discussion of the problem of copying IBM-360 machines.The minutes of the meetings concerning the copying of the IBM 360 machines from December of 1969 testify to the intensive discussions held.
Rameev did not agree on the decision of the country's leadership on copying IBM-360 machines.Notwithstanding, he went to work for the State Committee on Science and Technology of the USSR [7].Here he conducted the large scientific and organizational work on the formation of the all-Union scientific and technical programs for the creation of computer hardware and software.He coordinated the construction of systems for the automation of scientific research and design work, as well as for the introduction of automated control systems into practice.Furthermore, he contributed to the creation of the State Fund for Algorithms and Programs.Only the absence of a diploma on graduation did not allow him to run for a full membership in the Academy of Sciences, of which he would have deserved to be a member.Rameev came from the family of the largest gold miners in Russia.Bashir's grandfather was a famous Tatar poet.His father was repressed and perished in labor camps during Stalinist purges.Bashir Rameev, who by that time was a sophomore at the Moscow Power Engineering Institute, was named the son of an "enemy of the people" and was expelled from the institute [7.Many years later, in 1962, forty-four-year-old Bashir Rameev was awarded the academic degree of Doctor of Technical Sciences without defending his dissertation.Positive recommendations were given by academicians S. A. Lebedev, A. I. Berg and Corresponding Member of the USSR Academy of Sciences I. S. Brook [7].
In 2018, Rameev would have turned 100 years old, but there are specialists still alive who remember him very warmly, both as an outstanding scientist and as an extremely modest and talented person.They remember his kind eyes and smile, but at the same time remember his intransigence if he were convinced of anything.They remember his ability to gently convince, but firmly to achieve the ideal performance of all the necessary work.The many specialists who worked with Rameev note his attention to detail and the broadest technical intuition, the basis of which was the deep knowledge from different fields of technics.His commitment to unification, which is considered the cornerstone of effective mass production, showed a high level of computer construction.Rameev's name was often absent in the list of venerable speakers at various conferences, but this did not in the least interfere with his authority and popularity of the Penza scientific school he was leading.This holds true also thanks to the enormous creative work invested by him and his team in the development and production of universal computers.
In 2015, a technological park in the sphere of high technologies was named after Rameev to commemorate him.Technopark "Rameev" is an association of legally independent small and medium-sized innovative enterprises in Penza.The purpose of the technopark is to create favorable conditions for the development of small and mediumsized enterprises engaged in the development and implementation of innovative projects.

Exhibits and Documentary Collection of B. I. Rameev at the Polytechnic Museum

"Ural-1"
To date from the hundreds of UDSSR first-generation tube computers, only a single one has survived in full equipment -at the Polytechnic Museum.In 1967, the Voronezh State University gave the Small Automatic Universal Computing Machine "Ural-1" to the Polytechnic Museum (Fig. 1).Of course, the museum exhibitions in which the device is turned on and demonstrated how it worked cause the greatest interest of museum visitors.All of the authentic parts of the "Ural-1" computer are almost impossible to restore, but the processor and the RAM can be implemented on modern microchips.When studying the state of the "Ural-1" computer, it turned out that the control panel and the display panel are still working and can be used to demonstrate the operation of this machine.In 2007, two students developed the demonstration complex based on the Small Universal Automatic Electronic Computer "Ural-1" in the Polytechnic Museum.This complex along with authentic machine parts includes a number of additional blocks implemented on programmable logic microchips.This demonstration complex fully supports the command system of the computer "Ural-1" and with its help it is possible to solve any problems which were possible to solve on the original machine.
The bit grids and the ways of representing numbers and operations on numbers correspond completely to the real "Ural-1" computer.
The created demonstration complex includes: 1. Power supply system of the "Ural-1" computer.
3. The display panel of the "Ural-1" computer.4. The processor, which is the full functional analog of the "Ural-1" computer processor and implemented on the Field Programmable Gate Array (FPGA) chip XC3S200-4FT256C from "Xilinx".5.The operative memory simulating the operation of a magnetic drum of the "Ural-1" computer, implemented on an asynchronous memory chip IS61LV25616AL-10T, manufactured by ISSI.6.The device for long-term data storage simulating the operation of a tape and / or magnetic tape drive, implemented on the microchip M25P16, manufactured by "ST Microelectronics".
In order to fully interface authentic devices of the "Ural-1" computer and devices simulating the operation of the processor, operative and long-term memory, the following devices were additionally developed: 7. The block of interrogation of the section of buttons and toggles of the control panel, and also the block of interrogation of keyboard sections of the control panel, realized on microchips ИР22 and ИД7. 8.The output unit implemented on the registers ИР 27, ИД 3 and ИД 7 decoders, as well as the buffer elements HCF4050BE.
9. The optoelectronic isolation block, implemented on optotriacs (triode for alternating current) MOC3041, manufactured by "Motorola".The operation of the "Ural-1" computer was demonstrated to all categories of museum visitors until the closure of the main building of the Polytechnic Museum for major overhaul in 2014.The following mathematical problems were proposed for solving: demonstration of binary number system, demonstration of counting and displaying numbers in Gray code, demonstration of addition of small integer binary numbers, demonstration of operations of subtraction and multiplication based on addition operation, game "Guess Number," game "Tic-Tac-Toe," demonstration of the normalization of fractional numbers with a fixed point and obtaining floating-point numbers.The language of the intermediate presentation of the Ural-1 computer programs, called UASM'07 (Ural Assembler), was specially developed for this demonstration complex.
An automatic translator of this language in the machine codes has also been developed.

Documentary Collection
The exhibits of the collection "Electronic digital computing machines" of the Polytechnic Museum were complemented and supplemented by a documentary in printed and pictorial materials [4, 5, 6,].From 1989, the museum implemented the program "History of Engineering Thought in Russia".One of its goals was the creation of a database on the heritage of outstanding Russian scientists.The results of this program were reflected in the series of publications "Problems of Cultural Heritage in the Field of Engineering".Within the framework of this program, items related to the biography, scientific and official activities of the computer creators in the Soviet Union and Russia were collected and continue to be collected.An important component of the documentary collection is the personal documentary collections of the founders of domestic computer technics.
We opened fourteen personal documentary collections on "Domestic Science and Engineering Schools in the Field of Computing and Informatics."The Polytechnic museum holds documentary collections of academician S.A. Lebedev, academician V.M. Glushkov, corresponding member of the USSR Academy of Sciences I.S. Brook, his disciples -M. A. Kartsev and N. Ya.Matyuhin, talented creator Rameev and Yu.Ya.Bazilevskiyi, the developer of the only ternary computer in the world, N. P. Brusentsov, mathematician S. N. Mergelyan, organizer and leader of the first in our country hydraulic analogies laboratory V.S. Lukyanova, Director of the Moscow Factory Accounting Machines V. S. Petrov, founders of the national school of cybernetics A. A. Lyapunov and A. I. Kitov and academician V. S. Burtsev.
Among the above-mentioned collections, the personal collection of B. Rameev is the most voluminous and unique in its content.The documents of this collection reflected the entire history of the creation and development of domestic electronic computers.Rameev was not only the constructor of a number of domestic computers, but for more than 20 years he was engaged in coordinating the development and application of domestic computers, assessing their technical level and efficiency, the formation of scientific and technical programs, and the creation of the State Collection for Algorithms and Programs.In 1971, B. Rameev moved to the Main Department of Computer Technology and Control Systems of the USSR State Committee for Science and Technology.Because Rameev became deputy head of this department, documents related to the state policy of the development of computer technics are presented from the 1960s to the early 1990s.
In 1994, the activity of the researchers of the Polytechnic Museum on the acquisition of the Rameev personal documentary collection was timed to coincide with the anniversary date -the 40th anniversary of his basic development of the "Ural-1" computer.Rameev personally took part in the selection of documentary materials from his archive.For him, the manuscripts of academicians S. A. Lebedev or A. I. Berg and the office notes of the Penza period were equally important.Probably, due to his accuracy, discipline and careful attitude to the "memory" of the documentary, Rameev managed to keep a rich archive -both in terms of importance and volume of documents.Unfortunately, for health reasons, Rameev was unable to complete the work begun.However, the firm decision to keep the archive exactly where his first and most important brainchild, "Ural-1," is located, has found understanding and support of Rameev's relatives.Until 1998, the wife of the scientist, Vera Ivanovna Rameeva, continued to work with the museum.For four years, from 1994 to 1998, 438 items of storage were transferred, and the number of sheets of the documentary collection totals about tenthousand.
In 1999, after systematization and scientific processing, the personal collection of B. Rameev was opened at the Polytechnic Museum [17].It included items of clothing stock -the student's briefcase, the logarithmic ruler, the folder for papers, the Badge of Honored Inventor of the Russian Soviet Federated Socialist Republic, the Medal of the Exhibition of Achievements of the National Economy, etc.The most valuable items are the badge of the USSR State Prize and the Order of the Labor Red Banner.
The first textbooks on electronic digital machines by A. I Kitov and programming by V. N. Bondarenko, I. T. Plotnikov and P. P. Polozov were included in the collection of printed publications.They mainly document operational experience of "Ural" series computers and the development of their software.Also, famous domestic scientists and designers M. A. Kartsev, N. P. Brusentsov, and others are among the authors of the books of the Rameev's collection.The most unique printed publications include the materials of the conference "Ways of the Development of Mathematical Engineering and Instrument Making" (1956) and the abstracts of the reports of the V th All-Union meeting of users of the "Ural" computers (1966).The individual books have the stamp with the inscription "From the books of B. I. Rameev".The publications with the dedications from authors and users of the "Ural" computers are of great interest.They testify the wide scientific, business and friendly contacts between specialists (Fig. 7).
For an unknown reason, Rameev handed over a small part of his documents about himself to the State Museum of Political History of Russia in St. Petersburg.In the collections of this museum items like: a leaflet of a candidate for deputy of the Penza Regional Industrial Council of Workers' Deputies (1963), a membership card of the All-Union Society of Inventors (1935), Rameev's letter to chief of the Office for Inventions and Discoveries of the USSR Council of Ministers with a request for the resumption and revision of the case of a high-speed digital computer for the integration of differential equations (1950), and some others are stored.
Throughout his professional life, Rameev actively communicated with the leading developers of electronic computers in the Soviet Union.In particular, Rameev worked with Academician A. P. Ershov [18] on software issues.The archive of this scientist is stored in the Institute of Informatics Systems of the Siberian Branch of the Russian Academy of Sciences [19].It contained documents on the AutoCode project for a number of "Ural" computers, a single programming language for the "Ural" family of computers; on the draft technical specification of the software systems of the Unified Computer System "Ryad-3"; documents related to the work of the Interdepartmental Scientific and Technical Commission on Software of the State Committee of the Council of Ministers of the USSR on Science and Technology; documents on the reception of the delegation from the United States and so on.
Rameev's documentary archive, together with pictorial sources, was collected and formed personally by scientist throughout his creative work.The main custodian of the sources of Rameev's creative heritage in Russia is the Polytechnic Museum [17].A brief description of his personal documental fund is given in the Appendix.Rameev's granddaughter Anna Belkina-Tentler was doing a cartoon about him and published an article entitled "System Preferences: Animated Documentary about B. I. Rameev" [20]

Conclusion
Bashir Rameev fulfilled one of the key roles in the creation of domestic electronic computers and in the computerization of the Soviet Union.He left valuable legacy in the form of his developments of the family of universal automatic machines "Ural," a whole computer family with advanced software.
The main features of the new generation of computers embodied in the new series of "Ural," briefly boil down to the following.The machines of different capacities must be constructive, schematic and software compatible with each other.They should have a flexible block structure and a wide range of devices with a standard connection method, which allows selecting the computers package most suitable for a particular application and maintain the machine parameters in the process of operation at the level of changing customer needs and new device developments.
The exceptional merit of Rameev was the creation in the USSR not of individual computers, but of a whole family of computers compatible with software, the production of which he put on an industrial basis.Later, the institute created by Rameev in Penza was the "forge of cadres" for many institutes of computer technology in a number of cities of the Soviet Union.At the Main Administration of Computer Technology and Control Systems of the State Committee on Science and Technology of the USSR he was in charge of building an extensive system of computer facilities by organizing automated management systems for planning and processing information for various purposes and creating a state network of computer centers, united by communication channels.It is impossible to overestimate the contribution of Rameev to domestic electronic computing equipment.His name should be preserved in the history of Russia.

Rameev's Inventions
Rameev constructed the radio-controlled model of an armored train that moved along rails, shot a cannon, created a smoke screen.He presented it at a contest in Moscow.At the age of 17, he became a member of the All-Union Society of Inventors.

1940-41
Rameev proposed the method for detecting darkened objects from an airplane by infrared radiation passing through the curtained windows.He also invented a relay device for turning on loudspeakers in case of an air alarm.

1948-49
Together with I. S. Brook, Rameev submitted more than 50 patents for inventions of various Automatic Digital Computing Machines, part of which were issued USSR author's certificates.He proposed the project of the "Electronic Digital Analyzer" (USSR author's certificate No. 15153).

1948
Together with I.S. Brook, Rameev received the first USSR author's certificate No. 10475 from 4.12.1948 on the Automatic Digital Computing Machine.

1949-54
Rameev participated in the development of the first domestic serial electronic computer "Strela" in SDB-245 (Special Engineering Bureau).
1951 Rameev began to give lectures on digital computer technology to the fifth-year students of the Moscow Institute of Mechanics.

1953
Rameev chose a key method for developing small universal digital machines for engineering calculations: unification of circuit, constructive and technological solutions.The symmetrical trigger on a 6H8S tube, tested as the main element of the "Strela," became the basis for all new machines.Rameev made new decisions on the construction of panels, frames-corpuses, on the power supply and cooling systems of machines and others decisions [7,8,9].

1954
A team of developers, including B. Rameev, received the State Bounty for the first domestic serial electronic computer "Strela".

1963
For the first time in the USSR, Rameev proposed the principle of building computers and computer systems in the form of a number of software and information compatible machines.They were of various performance and completeness, built on the single element base with standardly connected peripheral devices.This principle was implemented in the models "Ural -11, 14, 16" and the digital computers of subsequent generations.

1965-68
He participated in the creation of systems for collective use and computer networks, as well as in the creation of automatized control system (ACS): "Bank", "Stroitel", "Lotus".

1968
Rameev suggested creating a number of software and constructively compatible computers based on the architecture of the System 4 family of the English firm ICL (International Computers Limited).

1971-94
Rameev was engaged in assessing the technical level of domestic digital computers, the formation of scientific and technic computerization programs in Russia and the creation of the State Collection for Algorithms and Programs.

Main Characteristics of Universal Electronic Computers "Ural"
With an occupied area of about 70 square meters, the Ural-1 machine contained more than 838 electron tubes, consumed about 7 kW of power and was able to perform 100 operations per second: addition, subtraction, transition and multiplication.The division operation was performed four times slower.The operative memory was realized on a magnetic drum.Its capacity was 1024 machine words or about 4.5 kB.A punched tape drive and a magnetic tape drive were used for data input and output of programs and data.The usual medium at that time was punched tape.An engineering control panel was used to control the machine.The machine printed the solution of a problem on a narrow strip of paper.A detailed technical description of the Small Universal Automatic Electronic Computer "Ural-1" can be found on the Virtual Computer Museum website [21].).Among the above documents it is necessary, first of all, to single out the project "Automatic digital computer," carried out in conjunction with I.S. Brook, as well as "Project considerations for the organization of a special design bureau for the development and construction of the Automatic Digital Computing Machine.The Advance project of the family of Ural-type automatic digital computers ("Ural-11," "Ural-12," "Ural-13," "Ural-14," "Ural-15") in five parts and the "Ural project -25" are of unconditional interest.These documents reflected the genius of B. Rameev, as the general designer of computers.) and 5 certificates of registration of inventions ("Ural-1," "Ural-2," "Kristall" computers, etc.).
