IBM 285 Tabulator with operator. "The card feed is at the top left and the card stacker below it a center left. The print unit is at the extreme right. Control switches are visible in the upper center, and above them the counter wheels of five accumulators. The 285 printed numeric data only and processed up to 150 cards per minute. The more expensive 405 (introduced 1934) could also print alphabetics. These were popular and long-lived models, IBM's biggest moneymakers until after World War II, and helped the new Social Security Administration automate its record keeping." The Tabulator was programmed with a plugboard.

IBM Type 016 Motor Driven Electric Duplicating Punch. "This was IBM's first punch with automatic feeding and ejecting mechanisms; it was marketed until 1960 (there was also an 015 model that lacked duplicating feature). The punching is done magnetically, and information from one card can be transferred automatically to another by a duplicator. The keyboard contains 12 punching keys, one for each row on the card. There are also space and eject keys. A master (program) card can be used to control automatic tabbing and duplication of fields. A skilled operator could punch 100-200 cards per hour on this model. Herb Grosch recalls, "You put a stack of blank cards in the feed [right], a single card, part of which you wanted to duplicate ('master card'), in the to-and-fro rack, and clipped a skip bar to the front of the carriage (p.82). A notch said skip, a deeper notch said copy."
