About the "at least one developed Russian microprocessor".
I would just remind you that it was in our country that discoveries were made, which (among many others, of course) formed the basis of almost everything modern IT. This is a quantum generator created by Bas and Prokhorov. This is a low threshold, continuously operating at room temperature semiconductor laser, which was made possible thanks to the research of Jores Alferov. Thanks to them - created semiconductor amplifiers of signals of the gigahertz range, without which it would be difficult to imagine the current mobile communication. This is a large number of theoretical and experimental research, without which it would be impossible to create modern microelectronics. It is space. In general, the contribution of our scientists was quite noticeable.
