Interesting! Those core memory photos would be a great addition to
Wikipedia if the photographer is willing to contribute them. For one
thing, that's actually a coincidence addressed memory, which the
current detail photo isn't. Excellent photography!
In fact, it looks like a memory with two inhibit wires rather than the
common single inhibit. This matches what CDC did in the 60-bit
mainframes (6000 series). But it isn't one of those because it has 7
groups of 8 rows, while CDC has 64 rows and colums per plane. 3584
bits per plane... very strange.
