My first computer programming used punched cards, and if you gave the deck to the computer center operator on Thursday, he or she would tell you to come back for the results Tuesday.
And ten years later, I had a computer with cassette drive storage, too.
My wife started as a key punch operator in Brockport Suny college. Four years later she was a supervisor there. At that time she was light-years ahead of me when it came to computers.
