Something that's fun reading, in spite of the
redactions is the 1986
National Security report on "General and Special-Purpose Computers: a
Historical Look and Some Lessons Learned":
A similar study from 1964 circulated a couple of months ago, in case
anyone missed it. Might be interesting to compare.
