The Z1 was a mechanical digital computer built by Konrad Zuse in Germany in the late 1930s. It was binary and did only floating point arithmetic. It had a Harvard Architecture. Hope that helps.

The Z2 used the mechanical memory of the Z1, but replaced the mechanical floating point arithmetic unit with a relay integer arithmetic unit.

The Z3 was all relays with only floating point arithmetic, but was destroyed by bombs in WW2.

After WW2 he resumed making better and better computers.
