Around 1990 my girlfriend and I visited Deutches Museum in Munich. At one point we both stood bent over a display intensely studying something when we were approached by an elderly gentleman. "I guess you are into computers?" "Yes we both are?" "Then I have a hot tip for you, around that corner they are working on restoring one of the old Z-machines to make it work again. Konrad Zuse himself is helping out." We vent there and saw three people concentrated around several very big blueprints. One of them was and old man with snow-white hair, holding a big yellowed sheet filled with a big mesh of electrical diagramming. Still going strong at the age of 80. A special gem to take away from that visit.
