40k Ferrite Memory Core

[Dave McGuire]

   I thought I recognized it, until I saw the last photo with the  
soda can.  Good heavens...that stack is HUGE!!

   I have one that's nearly identical, but about 1/4 the size of this  
one.  I was told it was from an early IBM 360, but I've still not  
verified that.
