Hi
The problem was RAM, not the control factors of relay logic. Relay
logic was widely use in the 40's.
Making a practical RAM was the difficulty.

Relays: Possible, but even in 1945 was very hard.
Available by 1901 at

Why do you say 'very hard'? I'm not sure when the relay was invented, but I
suspect it was way before 1901, given that the concept of an electromagnet was
so much earlier. The concepts I thought were well understood, at least within
the realms of telephony, by the 1940s.
