I didn't realize there is any such thing as non-destructive read core memory. Google
does turn up a few obscure articles about such things. It doesn't seem to have caught
on, and I wonder why it was used here.
So that phrase actually may be accurate. But does that clearly tie it to Gemini? And
even if it does, that doesn't amount to provenance as a flight item; it might just as
easily have been a spare, or a failed test module, or something similar that never left
the ground.

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.
