I would say digital a common relay has two states open or closed, when

Konrad Zuse built his first digital computer using largely relay logic
in 1940, but his work was not widely known until well after WWII due to
him working mostly by himself in Germany. He was aware that vacuum
tubes could be used as logic elements, even having one demonstrated to
him by a friend, but stuck with relays as they where easier to obtain.
All of Zuse's machines are digital. I find his mechanical memory most
interesting.

Quote on the Z1
There is a replica of this Model in the Museum of Traffic and Technology in
Berlin. Back then it didn't function well, and in that regard the replica is
very reliable — it also doesn't work well.
