If one were to
estimate the number of transistors in a penitum II
at 100 million (?), then if an exchange has ~three relays per number,
More like a
little more than a 1 million. With a 100 million transistor
CPU I could rule the world!!!
Assuming each relay occupied a cubic inch, one million relays would
occupy a cube 100 inches on each side, or just a bit over 8 feet on each side.
Not ridiculously large.
Of course, real relays much smaller than a cubic inch are readily available,
and a real computer of that density would have incredible cooling
problems.
