Thank you anon. After looking at it again, I can barely see the description of the holes on the top.
The most right one reads 12 V and the most left one reads 0 V. Unfortunately I can't read the ones in between.
Found something on the back.
It's from a school, department 'Polytechnik', which was a subject in east germany. It also reads 26 October 1977.
