An Early Sorting Machine

This is a sorter from the Computing-Tabulating-Recording Company in 1917. Punch cards were placed into the hopper and sorted into the respective stackers based on the content of one card column. A 10-digit account number required sorting the cards 10 times. This would have been a great year to buy stock in the company. In 1924, it became IBM.
