Didn't coincident-current relays come before that (as used, for example,
in telephone switching equipment)? So the basic idea was there.
I've always been fascinated by magnetic core logic; both using "hard"
magnetics (e.g. Univac SS) and "soft" (e.g. Parametrons). I wonder if
magnetic core for memory hadn't been developed, would we have developed
electrostatic or some other technology to the same density?
Would we have developed ultra-fast recirculating memory?
