Excursion Report Part 3: The Zuse Z23
The third part of our excursion to Erlangen was centered around the Zuse Z23 machine, which I already described in a previous blog entry about the Long Night of Science I attended some months ago.
Again, the demonstration of the machine was simply great - once more, thanks a lot to Volkmar and Edwin for hosting us!
So, here are some more impressions of the Z23 (original size photos available on request). All pictures are licensed under the Creative Commons CC BY-SA 4.0 license.
