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

Wang LOCI-2 Electronic Calculator
- Description
- One of the first programmable electronic calculators, this instrument was announced in 1964 and sold from 1965. It was designed by An Wang (1920-1990) and his associates. Wang, a native of Shanghai, immigrated to the United States after World War II, studied computer science at Harvard University, and worked at the Harvard Computation Laboratory. He started his own business in 1951, producing magnetic core memories and other electronic equipment on order. The LOCI or “logarithmic calculating instrument” was the first product marketed by the company. Two versions of the machine were announced: the LOCI I, which was not programmable, and the LOCI II, which was.
- The desktop machine has nine digit keys arranged in an array, as well as a zero bar and a decimal point key. Depressing other keys changes the sign of the number, shifts the decimal point, shifts from the logarithmic to the work register, and shifts from the work to the logarithmic register. Further keys are for arithmetic operations, squares, square roots, inverse squares, inverse square roots, inverse logarithms, and clearance of various registers. To the right are controls for the decrement counter, the program counter, and the operation code. According to company advertising, the machine offers ten-digit precision in addition and subtraction and eight-digit precision in multiplication, division, exponentiation, root extraction, and logarithm computation. It has five storage registers of ten-digit capacity and a ten-digit display, plus a display for the sign of the answer. A cooling fan and a cord are at the back. The card reader attachment that plugs into the back holds program cards.
- A tag on the front of the machine reads: LOCI-2. A tag on the back reads: ELECTRONIC SYSTEMS AND DEVICES (/) LOCI II (/) MODEL NO. 2AB (/) SERIAL NO. 2734 (/) TEWKSBURY, MASS. U.S.A. A paper tag on the back of the machine indicates that it was serviced 4/28/68, 9/12/68, and 2/9/71.
- According to a 1964 flier, the machine was to sell for $4,750.00. Kenney says that the initial price was $6,500. Wang Laboratories would go on to sell the 300 series of calculators (from 1966) and the 700 series (from 1969), and to manufacture minicomputers and networked microcomputers.

Texas Instruments SR-10 Handheld Electronic Calculator
- Description
- This is an example of the first model of a scientific calculator marketed by Texas Instruments. The handheld electronic calculator has a black and ivory-colored plastic case with an array of twenty-three plastic keys. Twenty-one of these are square, the 0 and the total keys are rectangular. In addition to ten digit keys, a decimal point key, a total key, and four arithmetic function keys, the calculator has a reciprocal key, a square key, a square root key, a change sign key, an enter exponent key, a clear key, and a clear display key. Text above the keyboard, just below the display and to the left, reads: SR10. Behind the keyboard is a 12-digit LED display. Numbers larger than eight digits are displayed in scientific notation. A mark behind the display reads: TEXAS INSTRUMENTS. An on/off switch is right and slightly above this.
- The back edge of the calculator has a jack for a recharger/adapter. A sticker on the back gives extensive instructions. It also gives the serial number SR10 275812.
- Unscrewing screws near the top and bottom of the back reveals the workings of the calculator. It has a total of five chips. The largest of these is marked TMS 0120 NC (/) C7333. This is a TMS0120 chip, manufactured in mid-1973. Also in the case is space for three AA nickel-cadmium batteries.
- The leather zippered case has both a loop and a hook for attaching the calculator to a belt. It also holds an instruction pamphlet entitled Texas Instruments electronic slide rule calculator SR-10, copyrighted 1973. A warranty registration on the inside of the back page indicates these instructions were originally sold with an SR-10 calculator with serial number 170334, purchased on September 27, 1973.
- Texas Instruments described the SR-10 as an “electronic slide rule calculator,” hence the “SR” in the name. The first version of the device, introduced in 1972, did not have the mark SR-10 on the keyboard. The second version (introduced 1973) and the third (introduced 1975) did. This is an example of the first version. According to Ball & Flamm, it initially sold for $149.95.

Handheld Electronic Calculator Prototype - Texas Instruments Cal Tech
- Description
- This prototype handheld electronic calculator was built in the Semiconductor Research and Development Laboratory at Texas Instruments in Dallas, Texas, by a team led by Jack Kilby (1923–2005), co-inventor of the integrated circuit. By the mid-1960s, TI was building microchips for industrial and military applications. The company president, Pat Haggerty, sought a consumer product that would use chips, just as earlier TI transistors had found wide use in transistor radios. Haggerty proposed a variety of possible products, and Kilby and his colleagues settled on making a small electronic calculator. TI had given an earlier development program the code name Project MIT. The calculator work, also confidential, was dubbed Project Cal Tech.
- Machines that performed basic arithmetic had sold from the mid-19th century, for use in business and government. Desktop electronic calculators with vacuum tubes sold from 1961, and with transistors from 1964. Kilby envisioned something much smaller that would be roughly the size of a book. This required a smaller keyboard, a new form of display, a portable power supply, and a new memory and central processor. Kilby assigned design of the keyboard to James Van Tassel, and gave work on the memory and processor to Jerry Merryman. He took responsibility for the output and power supply himself.
- By September 1967 Kilby, Merryman, and Van Tassel had made enough progress to apply for a patent. The submitted a revised patent in May 1971 and a further revision in December 1972. This final application received U.S. Patent No. 3,819,921 on June 25, 1974.
- The prototype resembles the “miniature electronic calculator” shown in the patent drawings. It has a metal case painted black and an array of seventeen keys and a zero bar. In addition to nine digit keys, there are keys for a decimal point, four arithmetic functions, clear (C), error (E), and print (P). The on/off switch is at the back right and a thermal printer with a thin strip of paper at the back left. The power supply plugs into the back of the calculator and into the wall.
- An inscription on the front of the calculator reads: THE FIRST CAL TECH (/) PRESENTED TO P. E. HAGGERTY (/) MARCH 29, 1967.
- Depressing a button on the front edge of the machine releases the cover and reveals an intricate “integrated circuit array” (to use the terminology of the patent description) and three chips. The array contained four integrated circuits, each the size of a wafer usually made with several chips on it.
- Further refinement of the Cal Tech led to the commercial Pocketronic calculator, introduced by Canon in Japan in 1970 and in the United States in 1971. Texas Instruments began selling calculators under its own name in 1972.

Hewlett-Packard HP-35 Handheld Electronic Calculator
- Description
- The HP-35 was the first handheld electronic calculator to display all the functions represented on a slide rule. It has a black plastic case and a total of thirty-five square or rectangular plastic keys. These include ten digit keys, a decimal point key and a pi key, all colored tan. In addition there are four arithmetic function left of the digit keys, a relatively long enter key, a change sign key, an enter exponent key, a clear x key, and a clear key, all in blue. Additional black keys are for powers, logs to base ten, natural logs, exponents, square roots, trigonometric functions (sine, cosine, tangent and the inverses of these), simple inverses, exchange, roll down, store, and recall. Above the keys is an on-off switch. There is no hole next to the switch to indicate that the display is on, as there was in the very first HP-35 calculators. Behind the switch is a red LED display that shows results. Numbers with absolute value between one hundredth and 10 billion are given in decimal form. Smaller or larger figures appear in scientific notation, with the appropriate power of ten occupying the three rightmost digit places (two for digits, one for a sign). The negative sign for the result, if needed, is at the far left. A mark on the front edge of the calculator reads: hp HEWLETT•PACKARD.
- The back of the calculator has a plug for a three-prong power adapter, a compartment for a battery pack, four rubber feet, and a sticker entitled: HEWLETT•PACKARD MODEL 35 INSTRUCTIONS. Text below the sticker reads: HEWLETT-PACKARD (/) 3.75V 500MW (/) MADE IN USA PATENT PENDING. A sticker inside the battery pack reads: HEWLETT-PACKARD (/) SER.NO. 1249A 11780. The portion 1249 of the serial number indicates that it was made in the forty-ninth week of 1972. A red sticker on the lid of the battery pack reads: CAUTION (/) USE ONLY H. P. BATTERY PACK (/) MODEL NO 82001A (/) OTHER BATTERIES MAY DAMAGE CIRCUITS. A sticker on the outside top of the calculator reads: PROPERTY OF (/) Dr. R. E. Zupko.
- In addition to the calculator, the gray plastic case contains a power adapter (1991.0210.01.2) labeled in part: HEWLETT - PACKARD (/) MODEL 82002A. It also has a carrying pouch (1991.0210.1.3). For the related manual, see 1991.0210.02.
- In this and a few other early HP-35 electronic calculators, entering the function 2.02 ln (e x) gave a result of 2 rather than 2.02. In this example, the owner chose not to have the error fixed.
- The donor, Ronald E. Zupko, was an historian of weights and measures and a professor at Marquette University in Milwaukee, Wisconsin.

IBM SCAMP
- Description
- Some personally operated computers, such as this one, came from companies traditionally associated with larger machines. In late 1972, the IBM General Systems Division in Atlanta, Georgia, asked the IBM Scientific Center in Palo Alto, California, to develop a product that would raise the visibility of the programming language APL. Paul Friedl and his colleagues in Palo Alto spent six months developing this pioneering portable computer, known as the SCAMP (Special Computer, APL Machine Portable). The prototype used existing components - a cathode ray tube from Bell Brothers, Inc., for the display; a Norelco audiotape cassette recorder for secondary storage; a keyboard from IBM in Raleigh, North Carolina; memory cards from IBM Germany; and a PALM microprocessor board from IBM in Boca Raton, Florida. The APL language processor emulated one for the existing, much larger, IBM 1130 computer.
- The SCAMP is designed to be a portable and folds into a suitcase-like frame. The upper part, including the monitor, pops up when in use. The frame is chocolate brown and the cover and upper part are almond white.
- Friedl and his colleagues used the SCAMP in over one hundred demonstrations. A menu on the screen indicated possible uses – as a calculator or for financial analysis, project planning, educational drill, engineering analysis, or statistical analysis. The machine served as a prototype for the IBM 5100 portable computer, a machine announced in 1975 that sold for between $8975 and $19,575 and found a range of applications. Some consider the SCAMP as the grandfather of the highly successful IBM Personal Computer (IBM 5150), introduced in 1981.

WorkSlate Microcomputer
- Description
- In 1983 Convergent Technologies, Inc., introduced this light weight portable personal computer. Advertised as “an information processing tool designed to meet business needs,” it sold with an integrated set of three business applications – memo pad, phone list, and calendar. At least eight other proprietary software worksheets were available.
- Power sources included AC power, or a NiCad battery pack, or four AA batteries. Two “button” type batteries (Union Carbide #186, made in USA) maintained the contents of the memory for about 7 days without other power sources connected. To conserve power, the WorkSlate automatically shut off after five minutes of non-use.
- The computer display screen is a liquid crystal display (LCD), approximately 6”w x 3”h. It displayed forty-six characters across and fourteen rows down.
- The sixty keys of the keyboard were color coded to indicate their purpose. Yellow represented principal operations such as backspace, cancel, on/off, and Do It. (The Do It key performs execute/enter functions). White identified the letters, numbers, and main punctuation marks. Keys marked in green were used in conjunction with the green “Special” key to access extended operations and characters.
- The microcassette player/recorder used 1½” h x 2½ w tape cassettes to load software worksheets, store data, and record phone messages.
- The computer included communication connections. Connected to a phone with standard RJ11 cable, it could be used as a speaker phone. Using the phone list application, it could auto-dial numbers. Using a microcassette, it could function as an answering machine. The Comm Port, when linked to the WorkSlate, provided the means to connect with other WorkSlate devices to send or receive worksheets, with printers, or link to a modem to access an electronic information service. According to the reference guide, by subscribing to an electronic information service, you could “receive data on almost any subject imaginable”.
