Chaika was not a copy of a Packard. (They certainly admired the Packard bodywork, but Soviet industry was in no way ready to clone a Packard sedan)

Tu-144 was not a copy of the Concorde. (Convergent evolution is not the same as copying a design!)

The Soviets did clone a lot of DEC gear but I don't think SM-1, specifically, was a DEC clone. (In this lastmost case, the Soviets were left cloning computer equipment because it was forbidden to export to COMECON states)
