An 8-bit slice processor for an East German PDP-11 clone. The chip was made by ZMD (Zentrum für Mikroelektronik Dresden) and used in SKR K 1600 (K1610/K1620/K1630) machines. If you got some information on this processor please contact me
 
Comment by Andrew Suvorow (suvorow1[at]mail.ru):
There were several PDP-11 clones made in Zelenograd near Moscow. Both multi-chip and, later, single chip versions.
 
Most quantities were 1801VM1 and 1801VM2. Second was much faster (over 10 MHz clock frequency). Both did not have extended addressing and were limited to 64k bytes address space. Later 1801VM3 appeared, containing 22 address extension much like PDP-11/70, but slightly different so original DEC programs could work with only 18 bit (256 kbyte).
 
These three CPU were not copy of any real chip from DEC. But there was another 5 chip CPU clone of DEC Professional 350. This model was cloned incredibly close, and called "Electronica 85".

The KP580BM80A (Kyrillic for KR580WM80A) is an i8080 clone produced in the former Soviet Union. It comes in a pretty heavy package with strange steel inserts on the back. I don't know why it had to be enforced like this...
 
Comment by Andrew Shkira (ashkira[at]ua.fm):
Those CPUs were manufactured in three variants:
 
KP580ИК80 - DIP48 ceramic package
KP580BM80 - DIP40 ceramic package
KP580BM80A - DIP40 plastic package
 
Comment by iguana_kiev (ddr2ddr[at]gmail.com):
Andrew Shkira`s comment is WRONG. Right info:
KP580BM80 - plastic DIP40 (after 1986)
KP580ИK80 - old name (up to 1986)
580BM80 - cerDIP40 military
K580ИK80 - flat 44pin ceramic (the first soviet CPU military)
Letter 'A' in the end means i8080A clone, no 'A' = i8080.

This soviet clone processor was used in scientific computers in 70's-80's.
