Historical Notes
Konrad Zuse pioneered automatic computing in Germany is the late 1930s.
Examples and restorations of early work are in Berlin and Munich Germany.

I always loved his vertually zero delay carry. At least
it was zero for relays. It was something that one
would not think of just looking at a single bit or
even normal logic of digital stuff.

Hi.
This week I had the pleasure to visit a Zuse Z23 on display in my city.
The Z23 is a first generation, discrete transistor and diode logic, drum
based machine with a small "cache" of core memory. It is hosted at the
Fraunhofer Institute for Experimental Software Engineering. Here is the
Press release regarding the Zuse machine:

Ohh, if you can't read german (at all we are talking about a german
computer ;-) ) here is the english version:

I took some pictures:
http://www.unixag-kl.fh-kl.de/~jkunz/bilder/Zuse_Z23/
The machine is in very good, but not working condition. I suspect it
would be a huge task to make it operable again, like the PDP-1
restoration. But it could be done. There is a complete set of
documentation, schematics, some spare parts, ... A former user of that
machine from the local university explained the machine and its inner
workings in detail to us. In one word: Fascinating! :-)
BTW: There is a tube based Zuse Z22 in working condition on display in
the ZKM museum in Karlsruhe (Germany). The Z23 is kind of a transistor
reimplementation of the Z22:
