Not a proof in entirety of the claim, but from a ref and looking at the closeup
pics from the auction website, it is an unusual form of core memory where the
cores have two holes through them, like a blocky figure 8, apparently an aspect
of a technique to achieve non-destructive readout. This is quite unusual and
would go some ways to showing a provenance to the Gemini project.
That scheme is also known as BiAx. The docs with my
Honeywell Alert machine described the same thing.
As far as I can tell, the EMM core memory unit that came
with it is NOT BiAx, however.
