Probably sold mostly to the sphere, not the core. Systime might have been in the pdp-11 business too but I was there working Vax, and the story was told to me about Vax (by systime employees I might add)
I remember using Soviet-made VAX clone from СМ ЭВМ series:
Your list misses SM-1700 ("СМ-1700"), a full clone of VAX-11/730. But all the VAX-compatible computers were produced only during the last several years of the USSR, so just a few thousand had been built in total.
well, except one of the most famous vaxen of all time, kremvax
