In 1965, the Baltimore Social Security Office employed workers to manually enter data into computers using a keypunch machine. Keypunch machines enabled data to be inputted into computers by punching holes into cards. These cards were then read into the computers, creating a digital record of the information.

The use of keypunch machines was a laborious process and required a great deal of accuracy and attention to detail. Workers had to carefully align the cards with the machine and manually type out the letters and numbers. This was a time-consuming process and it was essential that the data was inputted accurately.

The Baltimore Social Security Office was one of many institutions that relied on the use of keypunch machines to make the transition to digital records. Although the keypunch machine was eventually replaced by modern computers, it remains an important part of computing history.
