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
Moore Business Forms Continuous Forms Planning Rule
- This steel rule was used in the design of early computer printouts produced by dot matrix printers. The rule has a scale of 18" along one side, divided to 1/32" for the first two inches and then to 1/16". Each inch division, up to 17, is labeled with a number of punch cards, starting with 140 cards at 1" and going up to 2,380 cards. A hole 3/16" in diameter is placed at each 1/4" and 3/4" mark up to 11-1/4" (23 holes total). These were used for setting pinfeed holes down the side of the forms for continuous feeding.
- The center of the instrument has four holes 7/16" in diameter and four holes 5/8" in diameter. These are for designing holes to be punched in forms for filing. The front of the rule also has a scale of inches divided to 1/10", with subdivisions numbered from 1 to 130. This scale is a printer spacing chart, allowing the user to determine the space required for fields to be printed on the form, since each character required 1/10" of space. The rule is marked: MOORE BUSINESS FORMS, INC. Branches across the (/) United States & Canada. It is also marked at the right end: MADE IN U.S.A.
- The back of the rule has a scale of inches divided to 1/12" along one edge. Along the other edge is a scale in units of 5/32" that is numbered from 1 to 100. A scale labeled "RG" has divisions the same size and is numbered from 1 to 45. This side is also marked: MOORE BUSINESS FORMS, INC. Branches across the (/) United States & Canada.
- According to the donor, the 18"-size rule was considered more desirable than a 16" such as the example in the collections made by Graphic Technology (see 2006.0174.04). Fanfold paper such as that manufactured by Moore Business Forms was used from the mid-1950s into the 2000s, in association with both punched card equipment and computers.
