I apologise for any misunderstanding. By "clone", i didn't exactly mean
a 1-to-1 copy, but more a reimplementation. Much like the term "IBM PC
clone" is still used to describe non-IBM-derived PC designs.
Ok, sounds better, but the russians rolled out ther own CPUs too, that
makes a lot of difference in my eyes.
I understand that the eastern european countries can and di design their
own machines, but it's undeniable that the Soviet leaders deemed it more
valuable to copy western designs than design their own domestic
architectures from scratch. There was also plenty of designs that were
literal "clones", down to the silicon gates.
From what I read in the last 20 years I would state that the PDP11's are
far more spread all over the country as they where in the US. Belive it
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
One must know what he is doing to do that.
The russians "cloned" CPUs that never existet in original.
