A picture similar to this one was on one of my high school text books. Inside the cover was a description of it as magnetic core computer memory. For quite a long time I thought this is what computer chips looked like. The only issue was I was in high school in the 80s, long after such memory was used. Maybe the text book was 15 years old, I don’t know.

First computer company I worked for was still using it in the early 80s. Slow, but it retained state after a power failure.
