<One plastic box is labeled "Univac memory elements" and has a small sample
<of 3 size cores. The largest is about 1mm O.D. and the smallest is less
<than half that size. They look very fragile as the I.D. is almost as large
<as the O.D.

Those are about the size of the 8E cores.

<The other is a "Indiana General 15 mill memory plane" I guess the cores ar
<15 mill diameter. There are 16 cores wired as a 4x4 plane. The wires are

Big fat ones... not really. Those planes would be easy to drive and
understand. that would be one I'd love to try.

<much smaller than 30 SWG (about 28 AWG). I would say much smaller than 50
<(either) gauge, I need a magnifier just to see them.

I'd have guessed thinner than #40.
