The ARC-109 (F-111 AND C-5) and the Comm control of the ASQ-19 (F-4) have
magnetic core memory to store frequency channels.

>Back in '69, Data General core was going for $4000 for a 4 K Word plane.

But that's understandable for core memory.  I'd bet that today building
the same core would be the inflation adjusted equivalent of $4000.

The flight computer for the warhead bus on ballistic missiles 30 years
ago used plated-wire memory technology for ROM.  That has excellent
EMP survivability!
