Скачать или смотреть East German Comptuer: Robotron Z 9001 - Will it turn on after 37 years in a garage?

I found this beautiful machine in a garage in the spring of 2021, and now I think it's about time to figure out if it works or not!

The Robotron Z 9001 is a computer build in the East German Z80 clone, it does not even come with basic, you have to load that in from tape.
