On an early-computing data-processing line, you entered alphanumeric data into punched cards — keying source documents into the 80 columns of IBM cards (or similar formats) that mainframe systems would read for batch processing.
A typical shift involved sitting at a keypunch machine for hours — keying source documents into specific card columns, verifying through duplicate-punch verification, stacking output cards for downstream processing. The work ran in shifts at large data-processing operations, often with production targets measured in keystrokes per hour and error rate. The machines were loud and physically demanding.
The friction in the work came from the cumulative load of sustained keying — operators sat for full shifts maintaining concentration to avoid errors that would propagate downstream, and the keyboard required noticeable finger pressure. Employer variance shaped the experience: banks, insurance companies, government agencies, and large corporations ran shift-based keypunch operations through the 1970s; smaller offices ran lighter equipment.
The role suited people comfortable with repetitive precision work and steady under production targets — keypunch rewarded those who could sustain accuracy across long shifts. Most operators trained on the job, and many advanced into computer operations as the industry evolved. The trade-off was the eventual obsolescence as terminal-based and later PC-based data entry replaced the card workflow through the 1980s.
