I already understand the Paremetrons. I'd looked
into them before.
They work on the principle of the divide by two with these resonant
cores. Since the divide by two can take on one of two phase
relations with the clock, it can be one or zero by the phase.
There was (never commercially deployed, AFAIK) a scheme using
striplines doing much the same sort of thing with microwaves. I
recall reading about it back in the 60's. There are a couple of
"newly discovered" US patents on the subject, so I suppose the prior
art isn't well known.
At about the same time I seem to recall, there was a discussion of
encoding information in the form of nuclear spin in, for example, the
hydrogen nuclei in a bottle of water. The scheme is very hazy in my
memory, but one of the gotchas was that it was LIFO and not random-
access. Maybe someone on the list remembers more about this than I.
