Russia's electronics industry is not as developed as the United States, Japan and Europe, but still far above China. Russia and the United States are the only two countries in the world that rely entirely on their own technology to develop the electronics industry. In the world now generally accepted "Europe and the United States" environment, the Russian chip is difficult to get out of the country, so the Russians developed the trinary computer has not been accepted by the world. On the other hand, they also made compatible with the Western system of the chip, although the process is rough, but the reliability of the absolute first-class, I once got a piece of Russian chips, is a piece of compatible with the Intel-51 system of the MCU, I replaced it and a piece of 8031, the circuit works perfectly normal! It seems that the old Maoist stuff is also good compatibility.
As for the arms business, hehe, the Soviets like "violent aesthetics", so the arms industry developed a mess ............... ...
