The conventional--and convincing to me--story has been that they had
National Semi (and maybe others) help them with local fabs. These are
fabs for things like key chips (the ICs carrying keying material in
whatever form, for Permissive Action Links, and ultra-sensitive kinds
of stuff that they wouldn't the usual cranked-up fab workers in
Sunnyvale or Nampa getting near).
I heard ten years ago that the National Semi fab on-site was a lowly
2-micron fab. Which was enough for keying material.
Crunching chips, for special purpose computers, don't carry the same
security requirements, as the secret stuff in the code that is being
run and not the fuses or links being blown. For this, they would use
whatever is out there.
