Yeah!! I was always wondering if  they copied the exact electrical specs of
the Dec machines or they were simple "work-a-likes"  maybe software
compatible and able to run Dec  software but not interchanging parts.
I  only bring  this  up  as I see a Russian Pro-350 on ebay right now:
180760525391
It's relevant to  me as I picked up  a Russian DEC Pro  clone a couple of
years ago  (almost identical to the one  on Ebay now) but, unfortunately,
it  won't power  up. I always wondered if the  Russian hard drives  and
floppys might  work in my DEC Pro.
I  think my Russian machine may need a new power  supply  but  with no docs
or  schematics, the chances of  resurrecting it  or at least finding  the
fault, appear  to be slim and  none.
Cheers
Tom

 anyone here has taken one of the Soviet PDP-11 CPU clones and done
 anything with them.  In particular, I'm curious about the 64-pin DIP
 version with EIS.
 I've seen them offered a lot on eBay for very attractive prices.
 
  Me too; I've always been curious about them.  I seem to recall them
 having been discussed here a year or two ago, with the conclusion that
 there wasn't enough documentation available to actually build anything
 around them.
  I would love for that to not be the case!
