The first computers were actually women who held the
military job classification of "computer" which is what they did--they
worked in teams to perform simple mathematical operations and pass the
answers on to others who would combine those answers with others to
come up with a final answer to a much larger problem.
Electronic Numerical Integrator And Computer (ENIAC). It
spanned 150 feet in width with twenty banks of flashing lights
indicating the results of its computations. ENIAC could add 5,000
numbers or do fourteen 10-digit multiplications in a second.
"ENIAC" on a 7.44 by 5.29 sq. mm chip using a 0.5
micrometer CMOS technology. Even this technology is old now but I
refuse to keep changing these graphics ;-) (Moore School of Electrical
Engineering)
The first manned lunar-landing occurred on July 20, 1969
when Apollo 11descended to the moon's surface.
"The Eagle" had
to be landed manually by astronauts Neal Armstrong and Buzz Aldrin, as
their onboard "Apollo Guidance Computer" couldn't
process instructions
fast enough as the landing module sped toward a field of
boulders.
When I was a teen around 1977, one of the first personal
computers I ever used was called a Challenger 4P, it came in a kit in
parts and you had to supply your own TV and tape recorder. It had 4K of
memory and was very slow and it had a demo game called "Lunar Lander".
The game simulated the lunar landing mission of Apollo 11. The game
would often crash the computer. The computer cost about $2000.
This
is a Lunar Lander Applet written in Java that will
run in most browsers
on most machines. It cost nothing but I bet it will still occasionally
crash Windows machines.
