Computers & Business Machines
Imagine the loss, 100 years from now, if museums hadn't begun preserving the artifacts of the computer age. The last few decades offer proof positive of why museums must collect continuously—to document technological and social transformations already underway.
The museum's collections contain mainframes, minicomputers, microcomputers, and handheld devices. Computers range from the pioneering ENIAC to microcomputers like the Altair and the Apple I. A Cray2 supercomputer is part of the collections, along with one of the towers of IBM's Deep Blue, the computer that defeated reigning champion Garry Kasparov in a chess match in 1997. Computer components and peripherals, games, software, manuals, and other documents are part of the collections. Some of the instruments of business include adding machines, calculators, typewriters, dictating machines, fax machines, cash registers, and photocopiers

Electrotype Printing Block Showing a Manual Hollerith Key Punch
- Description
- This electrotype printing block is engraved in metal and attached to a wooden block. It shows a manually operated, key-driven Hollerith card punch with 11 keys. Hollerith patented such a machine in 1901, but it had only ten keys, numbered from 0 to 9. The machine shown on the electroplate has these number keys, plus one marked X.
- For key punches similar but not identical to that shown, see MA.335634, MA.335635, and MA.333894.

Record of Punching Cards at the New York Central for the Month of April 1904
- Description
- From 1895 inventor Herman Hollerith wooed the New York Central Railroad as a commercial customer for his tabulating machines. This small paper card records his success. It reports that in April 1904, key punch operators at the Central punched a total of 428,502 cards, averaging 258 cards per clerk per hour. The record for one clerk was 70,535 cards punched, averaging 413 cards per hour.

Tabulating Machine Company Card Punch
- Description
- From the early 20th century into the 1970s, Americans used punched cards to enter data onto tabulating equipment and then electronic computers. This early key-operated punch is based on patents of the inventor Herman Hollerith.
- The machine has a shaped iron base painted black that includes a grooved plate for cards, a mechanism at the back for advancing cards being punched, a single row of punches, and a group of 12 keys for punching round holes with these punches. Another key at the back releases the card guide. Nine of the thirteen rubber key tops are missing.
- A metal label on the front of the machine reads: THE TABULATING MACHINE CO (/) NEW YORK CITY (/) PATENTED (/) JUNE 18, 1901. SEPT. 10. 1901. A mark at the left front edge of the card bed reads: 17849. Two rods are marked at the front below the punching position: 234.
- The Tabulating Machine Company was formed by Hollerith in 1896 and merged to form the Computing-Tabulating-Recording Company in 1911. This firm became International Business Machines Corporation. The key punch was introduced in the U.S. in 1901 and remained in essentially the same form for over half a century.
