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

The Ohio firm of Tryom, Inc., introduced this electronic game at the Winter Consumer Electronics Show in Las Vegas, held in early 1979.
Description
The Ohio firm of Tryom, Inc., introduced this electronic game at the Winter Consumer Electronics Show in Las Vegas, held in early 1979. It is an electronic version of the game of backgammon, named for the actor and backgammon player Omar Sharif.
The flat screen keyboard includes twelve keys numbered from 1 to 12, as well as twelve playing keys and an on/off switch. Behind these is an LCD display. Text behind this reads: OMAR. A power jack is on the right side.
At the top of the back is a compartment for four AA batteries. Below this a sticker gives instructions. It reads toward the bottom: TRYOM INC. (/) Cleveland, Ohio 44122 (/) MADE IN U.S.A. It also reads Serial # 61508 (/) U.S. & Foreign Patents Pending (/) P113 REV.2.
The mark OMAR indicates that the term is trademarked. According to records of the U.S. Patent and Trademark Office, the firm of Tryom, Inc., applied for trademark protection for the term as used to refer to “equipment for playing a hand-held computerized backgammon game” in November 1980, receiving registration in December 1981. They had first used the term "Omar" in commerce in the summer of 1979.

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.
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.

After the Civil War, as American cities and businesses grew, business owners increasingly hired strangers to assist customers. At the time, it was all too easy for clerks and barkeepers to keep part of the money they received.
Description
After the Civil War, as American cities and businesses grew, business owners increasingly hired strangers to assist customers. At the time, it was all too easy for clerks and barkeepers to keep part of the money they received. The cash register, invented by the Ritty brothers of Dayton, Ohio, had a large display to indicate the sums customers paid. It also had a locked compartment that tallied total receipts. This is the Rittys' first machine, or an early replica of it. It was the basis for a commercial product called "Ritty's Incorruptible Cashier."
By 1884 the Rittys were out of business, but their patents were purchased by the National Cash Register Company. NCR made and sold much improved cash registers. By 1904, they were ready to convey the history of their company by showing this model at the St. Louis World's Fair. NCR went on to successfully make not only cash registers and accounting machines but electronic computers.

Description
In the 1950s Americans increasingly bought groceries in supermarkets, which served large numbers of customers. Consumers selected their own goods, and took them to a clerk who rang up sales. To make transactions as efficient as possible, the National Cash Register Company introduced machines that dispensed coins automatically, avoiding time and errors associated with making change. This change-making cash register went on the market in 1954, with a new model in 1958. This example was given to the Smithsonian by NCR in 1959, on the occasion of the seventy-fifth anniversary of the company.

The McCaskey Register Company of Alliance, Ohio, manufactured systems for keeping track of accounts and credit registers from its organization in 1903 until its purchase by Victor Adding Machine Company in 1953. The firm was started by Perry A.
Description
The McCaskey Register Company of Alliance, Ohio, manufactured systems for keeping track of accounts and credit registers from its organization in 1903 until its purchase by Victor Adding Machine Company in 1953. The firm was started by Perry A. McCaskey, a grocer in Lisbon, Ohio, who took out a patent May 19, 1896, for a “bill and account file” (#560523). He also patented a more complex “credit-accounting appliance” on December 30, 1902 (#717247). McCaskey contiinued to assign patents to the McCaskey Register Company through 1907, although ownership of the firm passed to others and several other inventors contributed to the product.
This particular machine combines a system for keeping accounts with a cash drawer. It has a wooden base with a wooden roll-top cover. A slatted panel designed for holding credit slips fits over the cash drawer and a piece of glass that fits over the panel. A silver-colored metal compartment is on the front of the cash drawer, with five buttons at the top. A bell is at the back on the inside.
McCaskey patents describe a system of credit slips that fit on bill-holders in the back of the machine. This machine has no bill-holders or slips.
The donor dated this machine to 1893. However, it was made after the McCaskey Register Company was founded in 1903 and resembles McCaskey’s 1907 patent, hence the later date assigned.

Description
This 1913 National Cash Register Company cash register has an ornate brass exterior with a marble plate above the cash drawer. In addition to the wooden cash drawer and pop-up indicators at the top, the machine had two rows of keys. Keys in the top row are numbered 90, 70, 50, 35, 25, 15,and 5 (the rightmost key is missing a label). Keys in the bottom row are labeled $1, 80, 60, 40, 30, 20, 10 (the rightmost key is missing a label). Inside a locked compartment above the keys is a register that reads dollars and cents up to $9999.99, a four-digit customer counter, and a two-digit no sale counter. The machine has no mechanism to assist the clerk in adding up totals for individual sales and no paper tape to serve as a receipt. It has serial number 1265603.
By this time, aggressive sales tactics, numerous acquisitions, and frequent lawsuits had won NCR dominance in the cash register market. The firm also trained numerous young executives, including Thomas J. Watson. When the U.S. government found NCR in violation of antitrust law, several of these executives, including Watson, were fired. Watson was soon hired by the Computing Tabulating Machine Company of Endicott, New York, becoming the president of a firm that soon was known as IBM.

The National Cash Register Company of Dayton, Ohio, expanded rapidly in the late 19th and early 20th centuries.
Description
The National Cash Register Company of Dayton, Ohio, expanded rapidly in the late 19th and early 20th centuries. It soon offered not only registers that kept digital records of transactions, but so-called autographic registers that simply allowed one to maintain written records of sales. This example consists of an oak box with a hinged lid, an opening in the lid that reveals a paper tape on which sales may be recorded, and a cash drawer. The decoration at the back of the register, the frame around the paper tape, and the handle on the door are of brass.
The National Size 45 autographic register sold in 1908 for $20.00. For related documentation see 1987.0751.03 and 1987.0751.04.
