"Computers were simple then"
Did computers really get more complex or just more transistors? :-)
I kind of like the comparison of chemical cameras (film or glass plate with
silver compounds) to digital cameras when compare complexity. I mean the
effect of electronics on photography has indeed been a revolution. But
actually, if you think of tiny grains for silver in emulsion as
electrochemical pixels you do see that old film was not that "Super Simple",
it was just easier to manufacture with simple tools.
I also marvel at that Apollo computer, and the fact the tools back then for
designing PCBs were rubylith and X-Acto knives. Like the pyramids there are
simply ideas that take tremendous engineering efforts to make happen.

I'm afraid it's not a space plane but just a plan.
Actually, there is something I always wonder about. Go back to Neil Amstrong
and that time...Apollo, for instance. The computers at that time were
simple, compared to today's machines. I know, because I passed a glass box
every day before I entered the clean rooms. In that box was Apollo's main
computer, which we built. Lot's of transistors, most TO-18 and TO-5.
Specked with 2N1893, 2121, 2902, which were very popular. Back to the
path.....as I said, very simple stuff. The main functions were 'small
push/pull rockets and main rockets, as long as the service module and the
astronaut capsule were together. And communication radios. And sensors of
various nature...but in alles rather uncomplicated electronics. My
question: The central station in Houston was a large room with lots and lots
of work stations. A hundred persons "worked" there, all with their noses
close to the many large computer displays.Why was it necessary with such
many work stations?
