had left the Soviet computer industry in disarray. Due to lack of common standards for peripherals and lack of digital storage capacity the Soviet Union's technology significantly lagged behind the West's semiconductor industry. The Soviet government decided to abandon development of original computer designs and encouraged cloning of existing Western systems (e.g. the 1801 CPU series was scrapped in favor of the PDP-11 ISA by the early 80s). Soviet industry was unable to mass-produce computers to acceptable quality standards and locally manufactured copies of Western hardware were unreliable. As

Early 1980s

The Soviet computer industry continued to stagnate through the 1980s. As personal computers spread to offices and industries in the United States and most Western countries, the Soviet Union failed to keep up. By 1989, there were over 200,000 computers in the country. In 1984 the Soviet Union had about 300,000 trained programmers, but they did not have enough equipment to be productive. Although the Ministry of Radio Technology was the leading manufacturer of Soviet computers by 1980, the ministry's leadership viewed the development of a prototypical

with deep skepticism and thought that a computer could never be personal. The following year, when the Soviet government adopted a resolution to develop microprocessor technology, the ministry's attitude changed. The spread of computer systems in Soviet companies was similarly slow, with one-third of Soviet plants with over 500 workers having access to a mainframe computer in 1984 (compared to nearly 100 percent in the United States). The success of Soviet managers was measured by the degree to which they met plan goals, and computers made it more difficult to alter accounting calculations to artificially reach targets; companies with computer systems seemed to perform worse than companies without them. The computer hobby movement emerged in the Soviet Union during the early 1980s, drawing from a long history of radio and electric hobbies. In 1978, three employees of the

American intelligence agencies, having learned about Soviet piracy efforts, placed bugs in copied software which caused later, catastrophic failures in industrial systems.

By early 1991, the Soviet Union was on the verge of collapse; procurement orders were cancelled ''en masse'', and half-finished products from computer plants were discarded as the breakdown of the centralized supply system made it impossible to complete them. The large Minsk Computer Plant attempted to survive the new conditions by switching to the production of chandeliers. Western export restrictions on civilian computer equipment were lifted in May 1991.

The few computers made in post-Soviet countries during the early 1990s were aimed at the consumer market and assembled almost exclusively with foreign components. None of these computers had large production volumes. Soviet computers remained in common use in Russia until the mid-1990s. Post-Soviet Russian consumers preferred to buy Western-manufactured computers, due to the machines' higher perceived quality.

countries could not export computers to the Soviet Union (or service them) without a special license. Even when sales were not forbidden by CoCom policies, the US government might still ask Western European countries to refrain from exporting computers because of foreign-policy matters, such as protesting the arrest of Soviet dissidents. Software sales were not regulated as strictly, since Western policymakers realized that software could be copied (or smuggled) much more easily.


Appraisal

Soviet computer software and hardware designs were often on par with Western ones, but the country's persistent inability to improve manufacturing quality meant that it could not make practical use of theoretical advances.

, in particular, was a major weakness of the Soviet computing industry. The decision to abandon original development in the early 1970s, rather than closing the gap with Western technology, is seen as another factor causing the Soviet computer industry to fall further behind. According to Vlad Strukov, this decision destroyed the country's indigenous computer industry. The software industry followed a similar path, with Soviet programmers moving their focus to duplicating Western operating systems (including DOS/360 and

, the decision was costly in terms of time and resources; Soviet scientists had to study obsolete Western software and then rewrite it, often in its entirety, to make it work with Soviet equipment. Valery Shilov considered this view subjective and nostalgic. Dismissing the notion of a "golden age" of Soviet computing hardware, he argued that except for a few world-class achievements, Soviet computers had always been far behind their Western equivalents (even before large-scale cloning). Computer manufacturers in countries such as Japan also based their early computers on Western designs, but had unrestricted access to foreign technology and manufacturing equipment. They also focused their production on the consumer market (rather than military applications), allowing them to achieve better
