Not really. You'd have thousands of very
fine wires, all looking
identical, that pass through some cores and go around others (on average
perhaps 33 through each core), and packed incredibly densely. Even with
very high resolution scans from multiple angles I don't think you could
expect to extract the data visually.
Okay, I see. Regardless--if it's that type of memory, then failure
to read it electrically could use a visual method as a fallback.
After all, these things were assembled (and one would expect,
inspected) manually.
