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

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.
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.

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.

Description
This is one of the first successful printouts of a program written in the computer programming language COBOL. After COBOL was proposed and described in 1959, programmers at Remington Rand Univac and at RCA wrote compilers that translated COBOL commands into machine language. They also wrote test programs to demonstrate the language. Like later COBOL programs , this one was divided into four sections.
The first identified the program and gave the name of the programmer. The second section, called the environment division, presented information about the specific machine used, such as the computer model, and locations to be used for different files. The third, or procedure, division was independent of the computer. It gave a series of statements about what the machine was to do. Although commands resemble ordinary English, the words used had very specific definitions and equations could be written using mathematical symbols. Finally, the data division defined the information to be processed. This data was entered so that it could be used in several programs, as in later database management systems. Successfully compiling a program produced a printout with each of these sections, as well as a listing of the desired results.
This printout of the first successful COBOL compilation at RCA relates to inventory control. One page is marked in ink: Good output – 8/17/60 (/) (isn’t it beautiful) (/) not really [the not really is crossed out] (/) well almost.

Description
This circular device was an aid to programming the UNIVAC solid-state computer. It consists of a paper disc with equal divisions running from 1 to 200 near the edge, and a clear plastic rotating disc that are pivoted together at the center. The upper disc is marked in red with two perpendicular diameters. The solid state computer had a magnetic storage drum on which locations were specified numerically. The latency calculator allowed programmers to write code for the machine to make the most efficient possible use of the drum memory. The back of the instrument gives a list of instruction codes and corresponding word times. Recieved in bag. Reference: Sperry Rand Corporation, Programming: Simple Transition to Electronic Processing UNIVAC Solid-State 80, 18-26.
Compare 2005.0271.01. Date based on date of documents 2015.3097.03 and 2015.3097.04.
According to Kirk Lubbes, who programmed the Univac Solid State Computer:
"The SS90 had a drum memory, i.e. memory was not random accessible. One had slow memory and fast memory. The slow memory had only a single read/write head per track on the drum and fast memory had four read/write heads spaced at 90 degrees, so therefore the drum had to rotate a full revolution to access a memory word in slow memory and only a quarter turn to access fast memory.
The trick in programming the SS90 was to have the instruction and its operand accessible at an optimal time so that the instruction could access its operand without waiting for the drum very far. As one started a program, this was not much a problem. The programmer new how much time that a given instruction would take to execute and the speed of the drum. Therefore, he calculated the position of the next instruction, based these two parameters. The minimum latency calculator was a mechanical device to help in this calculation. The problem was that as the programmer progressed, collisions occurred, i.e. the optimal location of an instruction or an operand was already taken by a previous instruction or operand. Since the drum was arranged in bands and the read/write heads were at the same location on each band, if one had a collision, you could put the necessary instruction or operand in a parallel band at the same position. This worked the bands all filled up.
The basic approach was to get a program working using the best latency that you could. Then the programmer would go back and start rearranging instructions and operand locations to achieve minimum latency. In those early times, machine time was expensive and memory severely limited. So it was important that production programs were efficient."

Description
In 1975, Novus, the Consumer Products branch of National Semiconductor Corporation, introduced a series of handheld electronic calculators known as the “Professionals.” As a June 1975 advertisement in the Chicago Tribune put it, these were designed to fill the gap between “very expensive calculators offering every feature in the book” and “‘Mickey Mouse’ models which were much less costly, but which just didn’t have what it takes to do the job.” The least expensive of these calculators was The Mathematician, which initially sold for $69.95. Others in the series included the Programmable Mathematician, The Financier, The Programmable Financier, The Statistician, The Programmable Statistician, and The International Computer (later sold as The International Converter). By 1976, Novus had also introduced The Scientist and The Programmable Scientist.
This is an example of the Novus Statistician. The calculator has a tan plastic case, thirty-two rectangular plastic keys, and a plastic display cover. At the bottom of the keyboard are ten digit keys, a decimal point key, and a clear key. To the right of these is a column of four arithmetic function keys. The function of these keys is marked on the keys themselves.
Above these keys are a total key and a variety of function keys and a clear all key. The function of all but the total key is indicated on the keyboard. A mark above the keyboard reads: Statistician. Behind the keyboard is an eight-digit red LED display. A mark above this reads: NOVUS. The jack for a power adapter is along the back edge and a power switch is on the left edge.
A battery compartment opens on the back of the calculator. A sticker on the compartment cover reads in part: BATTERY/ADAPTER (/) INSTRUCTIONS.

The handheld electronic calculator has a black- and ivory-colored plastic case with an array of twenty-four small rectangular plastic keys. In addition to ten digit keys, a decimal point key, a change sign key, a total key, and four arithmetic function keys, the calculator has a reciprocal key, a square key, a square root key, a pi key, an enter exponent key, a clear key, and a clear display key. Text on the keyboard, just above the keys and two the left, reads: SR-11. A constant switch is to the right of this. Behind the keyboard is a twelve-digit LED display. A mark behind the display reads: TEXAS INSTRUMENTS. The on/off switch is right and slightly above this mark.
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 SR-11 277378. A small sticker above this reads: INSPECTED (/) BY (/) J-01.
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 TMS0602NC (/) 7427. This is a TMS0602 chip, manufactured in mid-1974. Also in the case is space for three AA nickel-cadmium batteries.
The calculator comes in a black plastic zippered case.
Texas Instruments described the SR-11 as an “electronic slide rule calculator,” hence the “SR” in the name. Ball & Flamm indicate that the calculator sold for $66.50 in 1974.

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.

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 on the keyboard, above the keys and to the left, reads: SR-10. Behind the keyboard is a twelve-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 794630. A small round sticker above the large sticker reads: INSPECTED (/) BY L-01.
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 TMS0120NC (/) C7421. This is a TMS0120 chip, manufactured in mid-1974. 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.
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 in 1973) and the third (introduced in 1975) did. This is an example of the second version.
