40k Ferrite Memory Core

[Mike Loewen]

    I received this request for information on a core memory stack - does 
anyone recognize it?  I passed on some general info to him about core 
memory and how they work.

Hello,
I was hoping you could help me figure out what I have here.  I  bought it an
estate and it had a note attached that said  "40k Ferrite  Memory Core".  It's
pretty amazing to look at, there are thousands of tiny  wires and it has
little black "doughnuts" at the intersection of each  wire.  Any help in
identifying this would be greatly appreciated.
Thank You,
Scott
