40k Ferrite Memory Core

[Tom Uban]

I'm not any help in determining the machine that core
came from, but I do think that it is beautiful! Part
of what makes it cool to me is the three dimensionality
of the entire stack. And when I saw the final picture,
the one which had the soda can in it for reference, the
full size of the stack was realized!

What is to become of this core stack?
