The only thing new is the size. The April (naturally :-)), '72 issue of
EDN included an eight-page, full-color brochure from Signetics describing
their new 1 kbyte WOM. Functional block diagram, electrical (and other)
specs, etc., even a CONTEST! It was great reading, and I saved it for
years. Unfortunately, it must have escaped in the last move, as I just
looked for it and it is conspicuously absent.

The biggest problem, of course, is trying to be cost-competitive with
the bit-bucket.
