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

IBM 001Card Punch
- Description
- For the first half of the 20th century, much data was entered into data processing machines using punched cards. This machine for punching such cards was manufactured by International Business Machines Corporation of New York.
- This key-driven, manual punch has 14 black keys. Twelve are for the 12 rows on a punch card. These are labeled from 0 to 9, X, and blank. Another key moves the card one space to the left and the last releases it. Keys are fed in from the right. A portion of a punch card attached in back of the machine has a pointer attached to it which allows one to determine the column of the card one is punching. The device is set up for 80-column cards and punches rectangular holes. A cylindrical protrusion extends from the back of the machine.
- A metal tag attached to the front of the object reads: PROPERTY OF (/) INTERNATIONAL BUSINESS MACHINES CORP. (/) 001-12036-JH (/) ENDICOTT, NEW YORK, U.S.A. A mark stamped into the back of the card bed reads: 01 202.Two rods are marked at the front below the punching position: 202.
- IBM cards with rectangular holes and 80 columns were introduced in 1928. Cards with 12 rows of holes date from the early 1930s.

IBM Verifier for Punched Cards
- Description
- This key-driven, manual verifier has 15 black rubber keys. Twelve are for the 12 columns on a punch card. These are labeled from 0 to 9, X, and blank. Two other keys move the card one space, and the last key releases the card. Cards are fed manually from the left. A mechanism at the center of the machine senses whether or not a hole has been punched in a given line. If one depresses a key corresponding to a hole punched on the card, the card advances one place to the left. If the hole on the card does not match what is punched, the card does not move. Depressing the blank key at the front of the verifier then cuts a hole at the bottom of the column in which the error occurs. Erroneous cards are then retyped on a card punch. If the hole and the key typed match, the card advances one column.
- A mark stamped on the base of the machine toward the left reads: 05111993-A0.
- IBM introduced verifiers as part of its line of punch card equipment around 1917. Cards with 12 columns date from the early 1930s onward.
