here in the UK there are the royal institute lections put on basically

this year it was about computers and the main speaker was some bloke from
Microsoft and he said that the 'computer chip' on chip and pin cards
was 30 times faster than the computers that landed man on the moon
and the chip and pin had 1000 times the memory capacity too.
Not too sure how accurate it was to say that but I guess good enough for
a kids lecture.

I think that is pretty conservative. The Apollo and Lunar Lander
computers were really small memory units.

Even today anything that operates in space has a very small memory by
comsumer computer standards. The problem is radiation in space, and the
need for rad hard (radiation hardened) chips, especially memory chips. The
higher the memory density, the easier it is to be affected by radiation,
so the chips have very large memory cells. Features are larger on the CPU
chips also.

Plus, especially for man rated stuff like Apollo, the development of
failure statistics required stuff to either have been in use awhile, or
subject to accelerated life testing, and folks were not too sure of the
validity of accelerated life testing. The result was they went very
conservative on the technology used.
I have read that a Pentium 4 matched the processing power of the computer(s)
Nasa had in Houston for controlling Apollo 11. The 50s computer would have
its ass handed to it by a mobile phone, a digital camera or a palm PC... How
about home micros?
