Interesting.  I remember learning about the processes DEC used.  No fancy machines, just a flat plate jig with slots to hold the cores in their correct position, and nimble-fingered Oriental ladies to thread the wire through the core planes by hand.  Seemed sensible to me; that is the process I was thinking about for this case.
