  Altair 8800 Microcomputer Plug-In Card

  Description

  A computer board for the Altair 8800 microcomputer.

  Not long after Intel introduced its 8080 microprocessor, a small firm in Albuquerque, New Mexico, named MITS (Micro Instrumentation and Telemetry Systems) announced a computer kit called the Altair, which met the social as well as technical requirements for a small personal computer. MITS succeeded where other, more established firms had failed, and it was their machine that inaugurated the personal computer age. MITS got its start in computing in 1971, when it introduced an electronic calculator kit. Several thousand sold before 1974, when the sharp reduction in calculator prices drove the company out of that market.

  H. Edward Roberts, the Florida-born former U.S. Air Force officer who headed MITS, decided to design a small, affordable computer around the Intel 8080. His daughter named the new machine after the star Altair. It was the first microcomputer to sell in large numbers. In January 1975, a photograph of the Altair appeared on the cover of the magazine Popular Electronics. The caption read “World's First Minicomputer Kit to Rival Commercial Models.” According to the magazine, the machine sold as a kit for $395, and assembled for $498. Roberts had hoped to break even by selling 200 Altairs. Within three months he had a backlog of 4,000 orders.

  Enthusiasm for the Altair and other personal computers spawned computer hobbyist clubs, computer stores, newsletters, magazines, and conventions. By 1977, a host of companies, large and small, were producing microcomputers for a mass market. This phenomenon was abetted by a design decision to make the Altair an "open" machine. In other words, it passed data along a channel called a bus, whose specifications were not kept a secret. That way both MITS and other companies could add memory cards, cards to control a printer or other devices as long as they adhered to the published standards.

  This particular Altair was collected by the Smithsonian because it documents how hobbyists would outfit the machine with additional parts and components. The user added his own keyboard, monitor, disk drive, and 17 plug-in boards to expand the computer’s capability. Unfortunately, the original owner of the kit is unknown. The computer was donated to the Smithsonian by a second owner, Mark Sienkiewicz, who purchased it as a collectable item and never used it.

  Texas Instruments SR-51A Handheld Electronic Calculator

  Description

  This handheld electronic scientific calculator has a black plastic case with an array of forty small rectangular plastic keys. The white digit keys, a decimal point key, and a change sign key have only one meaning. The orange total key also has only one meaning. Pushing the gold “2nd” key changes the function of the other keys from what is shown on the key to the “dual function” indicated above it on the keyboard. The device calculated values of a wide range of arithmetic, statistical, logarithmic, trigonometric, hyperbolic trigonometric, and inverse trigonometric functions using the gold and brown keys. It also has limited memory.

  Text above the keys reads: TEXAS INSTRUMENTS SR-51A. Behind the keyboard is a switch that may be set at R (radians) or D (degrees). Next to it is an on/off switch. Behind the keyboard is an LED display that shows ten-digit positive and negative numbers and two-digit positive and negative exponents.

  The calculator has a jack for a recharger/adapter along the back edge. A sticker on the back gives codes entered to convert from common measures to metric measures and vice versa. It reads in part: TEXAS INSTRUMENTS (/) SR-51A. It also gives the serial number SR-51A 125990. Text at the bottom of the sticker reads: Assembled in USA. Text below the sticker reads: 4575DTA. Above the sticker is a compartment for a battery pack. An owner’s mark along the side of the calculator reads: Joanna Spain 550-25-3136. The same mark is on the inside of the back of the calculator.

  Unscrewing four screws on the back reveals the workings of the calculator. It has six chips, two relatively large. One of the large ones is marked: TMC0523NL (/) AΔ7529-5. This is a TMC0523 chip, manufactured in mid-1975. The other is marked: TMC0501NL (/) DΔ7531-6. This is a TMC0501 chip, manufactured the same year.

  The calculator comes in a black plastic, zippered case with belt loop.

  Compare 1986.0988.357 (the SR-51) and 1986.0988.358 (the SR-51 II).

  International Dial Time Recorder Clock

  Description

  Showing up for work punctually, at an official time, became expected behavior toward the end of the 19th century, as more and more people worked for others rather than for themselves. Not just the work force's punctuality was at issue. Cost accounting and analysis--recording and scrutinizing expenses for labor, materials and overhead--were getting more attention than ever before. Time was money.

  In the 1890s, timekeepers-- clerks who kept track of employees' hours in handwritten logs --found that machines were beginning to replace them, especially in workplaces with large numbers of employees. Thanks to the influence of the advocates of scientific management, nearly every industrial workplace had a time clock, after about 1910. So did many offices. By the early twentieth century the International Time Recording Company supplied an entire line of timekeeping devices, including master clocks, several types of time clocks, and time stamps. Founded in 1900, the firm continuously expanded its product line, underwent several reorganizations and name changes, and emerged in 1924 as the International Business Machine Corporation, familiar today as IBM.

  One of the firm's most popular products was the dial time recorder, a clock that could furnish a daily or weekly record of up to 150 employees. Based on the 1888 patent of physician Alexander Dey, the dial time recorder was essentially a spring-driven clock with a cast-iron wheel affixed to its dial side. The rim of the wheel was perforated with numbered holes. As employees pressed a rotating pointer into the hole at their assigned number, the machine recorded the time on a preprinted sheet and rang a bell with each punch. A two-color ribbon printed all regular time in green and all tardiness, early departures, and overtime in red.

  This International dial time recorder hung in a factory in the garment district of New York City.

  Keyboard for Green Machine Prototype Electronic Calculator

  Description

  As a graduate student in electrical engineering at the University of California at Berkeley, Thomas E. Osborne began thinking about the design of a desktop electronic calculator suited for calculating the very large and very small numbers encountered in scientific work. In January of 1964, he formed the firm Logic Design, Inc., to develop his ideas. By late 1964, he had built this prototype keyboard and display, as well as a prototype logic unit (1978.0311.02).

  The keys are of plastic, the case of balsa wood painted green. The prototype is known as “the green machine” from the color of the paint.

  The model has an array of nine digit keys on the right front, with zero, decimal point and exp keys above them. On the left are twelve keys for arithmetic operations, clearance, and memory access. After damage to the case, it was reconstructed by Osborne before it came to the Museum.

  For related objects, see 1978.0311.02. For related documentation, see invention notebooks and photographs by Osborne (1978.0311.03 through 1978.0311.14). For purchase orders of components used in the prototype, see 1985.0264.01. Elements of the green machine were incorporated in Hewlett Packard’s first commercial electronic calculator, the HP9100. For a prototype of that machine, see 1978.0311.03.

  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.
