Okay, one thing the Soviet Union was not known for was having good electronics and computer systems.
Actually it is not as straightforward as you present. Despite initial time lag in late Stalin's times (cybernetics had been generally banned and called "whore-science of capitalism", as it showed that Soviet economic system was inherently unstable), Soviets generally held their own in late 1950s-early 1960s. They had decent small-series big iron for defence and industrial applications. They started to lose exponentially once development of integrated circuitry opened the way for relatively cheap, reliable and high-performance machines for general business and (especially) finance. Soviet Union simply did not have an
obvious need for such technology and consequently failed to allocate decent resources to develop it (remember, that none of current leaders of electronic industry emerged in industrial/defence area, they all sprang up from consumer electronics, as Sony and whole Japanese gang, or finances, as IBM). Once Soviet leaders understood depth of the gorge they threw themselves into, they made heroic effort to bridge it, but it was too late. It all happened pre-1980, therefore pre-PC. Frankly speaking, short of some uptimer influence to force Soviet leaders to invest heavily in such problematic area, I can't imagine a way for USSR to turn into IT powerhouse. They always had good analysts and knew that computer system capable of radically altering Soviet centralized planning was (and still is) impossible at current level of technology.
Do not drop the PDP-compatible ES machines for 8086-ripoffs and later make personal version of these.
ES (short for United Line of computers) were reverse-engineered IBM360/370. Soviet clones of DEC microcomputers were called SM (Small Machine).
