You operated the keypunch — a desk-mounted machine that punched holes into 80-column data cards — entering alphanumeric data that mainframe computers would read through card readers for batch processing.
The machine sat at the center of the role — a typewriter-style keyboard above the card hopper — with operators feeding blank cards in, keying data, and stacking punched cards for downstream processing. Verification cycles often required a second keypunch operator to re-key the same data on a verifier machine. Keys-per-hour and verified-card accuracy were the operating measures.
The harder part was often the precision needed at production speed — wrong column entries cascaded into downstream batch-processing errors, and operators learned to balance throughput against careful work. Operator variance shaped the work: large data-processing centers ran shift-based keypunch pools; smaller business-office settings ran single-operator stations.
The seat fit people patient with repetitive precision work, comfortable under production targets, and steady through long shifts. Many keypunch operators moved into computer operations, data control, or supervisory roles as their experience grew. The trade-off was the body cost of seated keying work — wrists, shoulders, and back carried the load, and the eventual displacement by terminal-based entry retired most keypunch positions through the 1980s.
