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.

This is quite unusual and would go some ways to showing a provenance to the Gemini project.
