[Tfug] Punched cards and paper tape.

WOW, 5,000 cards! That is a lot, and you took a single fortran class? I am
impressed.

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.

In '69 I did not work on IBM iron, but I designed and built and simple
Half-Adder <http://en.wikipedia.org/wiki/Adder_%28electronics%29>  that I
made in to a calculator and then with point to point wiring made a computer
of sorts.  Building various Popular Electronic projects until building an
Altair around 74.  even had an article in Pop-Elect around that time, can't
remember what is was,  a simple light controller

OK, who among this list learned how to wire/program a IBM 407 accounting
machine? Or a 557 card reproducer (I think it was a 557, may be 559 too many
years ago). That was a lot of fun!! :-)

You just pulled in the entire list.

So which of you folks had a Commodore 64?

Long after that, I did some statistics at the UA using punch-cards, and I
think 
that was in '78 or '79.

Finally parted with mine a few years ago. [sigh].
