IBM Keypunch
This is the type of IBM keypunch machine used in the 1960s and 1970s. Operators by the tens of thousands would spend a full shift keypunching orders, time cards and a host of other transactions.

I payed for my college education with this machine!
Of course, we were required to produce 2,000 cards per hour, and that was the most difficult job that I have ever had in my life.
