The A6 intruders during the Veitnam era were serial based on
a fixed disk. It was part of the nav and targeting system and
not fly by wire.

I recently had a memory unit for an EA-6. It used core memory. It
was
SN 001 and the ICs dated from 1966 if I remember
right. Of course, there
was probably more than memory in the EA-6. I sold the unit but I can dig
out the description and pictures if anyone's interested.
EA-6 is later and used updated hardware.
It's hard to think of core memory as "updated" hardware. :-) I hate to
imagine what an *earlier* fixed disk looked like!
