I was hoping to find an updated version of this, but I guess computers haven’t gotten any Moore compact since (lemmy.world)

Another unusual feature is the use of magnetic cores not only for memory but also as logic gates. These logic cores have 1, 2 or 3 input windings, a trigger (read) and an output winding. Depending on their polarity, current pulses in the input windings either magnetise the core or cancel each other out. The magnetised state of the core indicates the result of a boolean logic function.

Huh. Clever.

    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.
