Ok, sounds better, but the russians rolled out ther own CPUs too, that
makes a lot of difference in my eyes.

Most of us know that the PDP11's archtecture is an elegant design and it
was the blueprint of Z8000 and MC68000 (MSP430). It must have had favored
from russian programmers..as I already wrote above even Tetris was
programmed on a russian PDP11.
...but this hasn't happened since the CPUs got copied, they rolled out
ther own thing.
Even the "cloned" Z80 from the former GDR wasn't a clone at all. Zilog
Z80 have Bugs in the Flag handling for example, which the GDR U880 has
corrected.
One must know what he is doing to do that.
The russians "cloned" CPUs that never existet in original.
