[Tfug] Punched cards and paper tape.

Thought I'd put in my two cents. In '64, I went to work for lockheed
Missiles and Space Co. in Sunnyvale, Calif. I worked in a team of 40
engineers known as Loads and Dynamics Analysis. I was the only one with
any computer skills at all which resulted from a two unit FORTRAN course
I'd taken at Purdue University. My main job was to maintain and execute
a a FORTRAN program that modeled the launch of a Polaris missile from a
submarine and calculated the shear forces as the missile exited the
launch tube for specific roll, pitch and yaw motions of the submarine
and wave conditions as well as arming configuration of the missile. The
program was some 5,000 lines of code all on punch cards. When one of the
engineers wanted to see results for certain conditions, I'd type up some
data cards, properly place that data at the end of the two and a half
boxes of cards, put the boxes on a cart, wheel that cart down the hall
and hand them through a window to a computer tech. The next day, I'd
return to pick up the output. The computer was a Univac 1107, said to be
one of the most advanced machines at that time. It was housed in what
I'd imagine was a 10,000 sq. ft. room that was substantially air
conditioned. Amazing that I now have thousands of times as much
computing power at my finger tips and it all sits on my lap.
