Zuse Z4 - Oldest Surviving Computer in the World - Lost in the archives

It is going to need a lot of contact cleaning.
The one thing I like is the carry design the Zuse used. Really fast for relays but not of much use for solid state.

A few days ago, it was published on BLOC at CACM that a lost user manual
for the Z4 and notes on flutter calculations was found in the ETH Zürich
archives. See:

Zuse Z4, a relay computer of 1945,  however, due to lack of
documentation, its functionality was largely unknown. Now a manual for
the machine has appeared at ETH Zurich, that was buried in the archives.
And this in the digital age ...
