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

National Cash Register, Model 79
- Description
- This large, nickel-plated, manually operated cash register is an NCR Model 79. It has three columns of keys for entering numbers, and a fourth column of function keys. The operating crank is on the right side, the cash drawer is below, and a receipt dispenser on the left side. Pop-up indicators above the keys indicate the total purchase. The Model 79 was introduced by NCR in 1892, this example dates from 1894. Principles introduced with this cash register would prove important on numerous later NCR cash registers. For a model of part of the mechanism of this machine, see MA.316703.

Mechanism from National Cash Register, Model 79
- Description
- By 1894, when this device was made, the National Cash Register Company had developed an adding mechanism in which digits were indicated on the rim of rotating wheels. This is such a mechanism. The three wheels could rotate to show totals as high as $9.99. Four other wheels on the left side each have the digits from 0 to 9 around the edge. The mechanism is mounted on a white wooden display board.
- A mechanism of this type was used in the NCR Model 79 cash register (see object MA.316701). NCR went on to develop a more compact mechanism that could represent eight totals, rather than just one, on a single shaft. See object MA.316704.

Counter from a Hollerith Tabulating Machine
- Description
- This is a single counter from a Hollerith tabulating machine. It has square brass pieces on top and bottom, with a brass mechanism in between. A paper-covered metal dial on top is divided around the edge into 100 equal parts. Two hands are on the face of the dial. Advancing the small hand by 100 (one revolution) advances the large hand by one. Hence the counter can read up to 9,999.
- A mark around the center of the dial reads: THE HOLLERITH (/) ELECTRIC TABULATING SYSTEM (/) PATENTED, 1889.
- Compare to the dials on MA.312895.

Hough's Security Cash Recorder
- Description
- In the late 19th century, as American shopkeepers hired strangers to work in their stores, they showed a new concern for keeping track of retail transactions. Azel Clarence Hough (1859-1946), the son of a creamery owner in South Butler, New York, took out a range of patents for the design and improvement of cash drawers between 1892 and 1899 (U.S. patents 484501, 486107, D22024, 534795 and 618034). His ideas served as the basis of the products of the Hough Cash Recorder Company of Indian Orchard, Massachusetts.
- This example of Hough’s Security Cash Recorder is a large oak box with an oak lid. At the front on the right is a lock for the cash drawer; the drawer is on the lower left front. On top is an opening that shows a roll of paper. Salesclerks were required to enter a total on this paper roll and advance it in order to open the cash drawer.
- This model is quite similar to the Hough Security Cash Register No. 70 shown in an advertisement reproduced in Crandall and Robins, p. 318. This machine sold for $15. Hough Cash Recorder Company advertised in Hardware Dealer’s magazine as late as June, 1906. However, its products were soon outpaced by the autographic registers sold by NCR.
- In the early 20th century, Hough became interested in the manufacture of wooden blinds, and took out several related patents. He first manufactured shades in South Butler, then in Worcester, Massachusetts, and then in Janesville, Wisconsin. The Hough Shade Corporation he formed survives under the name of Hufcor.

Hollerith Card Sorter
- Description
- During the 1880s the engineer Herman Hollerith devised a set of machines for compiling data from the U.S. Census. Hollerith's tabulating system included a punch for entering data about each person onto a blank card, a tabulator for reading the cards and summing up information, and a sorting box for sorting the cards for further analysis.
- This third part of the system, the sorter, is shown on the right in the photograph. It is an oak box with 26 vertical compartments arranged in two rows. Each compartment has a brass cover that is held in place by an electric catch connected to the tabulator. The sorter is connected by a cable to the tabulator. Once a card is read by the tabulator, a compartment opens in the sorter, indicating where the card should be placed for further counting. The front and back sides of the sorter open so that one may remove stacks of cards from the compartments.
