I bought one of this CPU Clones too a while ago. Never found good
documentation apart of a 2 sheet datasheet.

 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!
