In 1964, I had a summer job programing {mechanical) voting machines for the presidential election...

I assume by "programming" you mean making sure all worked correctly and were reset to zero? Hopefully not predetermining the outcome!

Duhhh, well of course.
There were no computerized machines then, and programing
consisted of inserting hundreds of spacers and other pieces of hardware to make turning a lever record for the indicated candidate.
Naturally,, all machines were then thoroughly tested by the election commission before being sent to the polls.
