What Zuse you are refering to? There are "many".

The Z22 at the ZKM sholud be complete and and operable. (If the people
at the ZKM have not ruined the machine meanwhile.) It is tube based and
was build 1958. It is a stored program machine for sure. Main memory is
a drum with 8192 words. It is original and has been kept in working
condition most if its lifetime.
