I'm VERY skeptical of this one! First, I know IBM went to
great lengths at some time in
the early 60's to figure out how to make reliable computers
with a LOT less gold than
the traditional wisdom required. As far as I know, all
360's had a LOT less gold in
them than similar-sized machines from other makers at the
On the other hand, a lot of gear from the mid-60's actually
used gold as the etch
resist on the circuit boards. I have some examples of
that. The traces of the
boards are totally plated with gold!
