They also had full VAX 11/780 clones! https://en.wikipedia.org/wiki/Robotron_K_1840
Oh and wonderful art ( http://imgur.com/GPPI56E ) but that's another topic.
I still think Robotron is about the coolest name of any computer manufacturer EVER. Imagine how cool it would be to own a laptop or smartphone or whatever with that name on it.
Since there were jokes further up, this reminded me of another one:
A delegation of Japanese visits the GDR and of course is shown many important companies and places. At the end, they are asked "What did you enjoy the most?"
"The three great museums: Pergamon, Pentacon and Robotron"
Hehe, that is a good one!
Earlier this year, I visited the Heinz-Nixdorf museum, not far from where I live, which actually has a mainframe built by Robotron on display (a clone of an IBM S/370, I think).
