I've never seen core in real life...... how small are the wires?
My 8/E 4k core looked to be about 40 gauge. The 8/E also had an 8k core
and the 8/A a 16k core. They would be even smaller.
Here is my pictures of the PDP-8/E 4kx12 core board.

Closeup of a small section letting you see the wires (select large size
to really see them).

Hi,
as promised, here are the pictures I took while having one
board open. Very delicate stuff indeed. This one is
16 k x 12 bit core.
