As I understand it... one of the reasons why the Soviets fell behind in computer technology was because back in the 60s, while Soviet engineers had good designs that were state-of-the-art for the era, the communist economic planners estimated the requirements for computer manufacture to be one per university or government department for a total of maybe a few thousand, while Western manufacturers were getting orders into the tens or hundreds of thousands... and they had to come up with new technologies to produce the machines faster and cheaper in order to keep up, let alone compete with other manufacturers. So the market in the west grew explosively, requiring concomitant growth in innovation, and that put the Soviets on the back foot, requiring them to smuggle in and reverse engineer System/370s, PDPs, etc. in order to stay current.
