How many people learned to keep an eye on the card reader so no one
could sneak by and slip in a blank card in your stack during crunch time
before a program was due?

I had toggle switches to program the whole stinking thing. 8 rows of 8
switches, a single switch as an "enter" switch and a light that flashed
to indicate the 8 bytes had been received. Didn't have a tape reader on
the main data collector but it did write to paper tape (industrial
control computer for taking machine floor samples of a multitude of
sensors during fabrication of large and medium power transformers) which
could be read by a separate machine that crunched numbers into a plotter
using the special, uniform density plotter paper. Then I could cut out
the curve shape (literally with a pair of scissors) and weigh the curve
as a method of computing the integral of the curve (find the area under
the curve).

The machine was rarely restarted since it took most of a full day for 2
people to key in the hundreds of bytes to run the thing.
