I visited a university supercomputer centre in Berlin that had been a merger of East and West Berlin facilities in about 1999. In the lobby they had a PDP-11 right next to the Eastern Bloc clone with its Cyrillic writing.
I probably have some old school photos somewhere.

Those are still standing in the lobby of the Computer Science Department of FU Berlin (Takustraße 9)
You are probably referring to Zuse Institute Berlin which is the building right next to it.

quote:
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".
That sounds a lot like the building at Takustraße 9, which is the main building of the computer science department of Freie Universität Berlin. When I studied there from 2011 to 2019 the both PDPs were still standing in front of the lecture hall. The Zuse Institut Berlin, which hosts a high performance computer is next door from it.
