Apple II Personal Computer

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

Radio Shack TRS-80 Model 1 Microcomputer

In the early 1970s, most personal computers came as hobbyist kits requiring a high level of technical expertise to assemble.
Description
In the early 1970s, most personal computers came as hobbyist kits requiring a high level of technical expertise to assemble. Don French, a buyer for the consumer electronics chain Tandy Radio Shack (TRS), believed that Radio Shack should offer an assembled personal computer and hired engineer Steve Leininger to design it. In the summer of 1977, Radio Shack introduced the TRS-80 for $599. This offering included a BASIC language interpreter, four kilobytes of RAM, a Zilog Z80 processor at 1.77 megahertz, a twelve-inch video monitor, a cassette recorder, a power supply, and a cassette tape containing the games Blackjack and Backgammon. While some Tandy executives were skeptical about the success of the PC market, the availability of the TRS-80 on five thousand Radio Shack store shelves helped the Model 1 sell over one hundred thousand units during its first year, half of total PCs sales in 1978.
The TRS-80 had its microprocessor inside its keyboard. While you could purchase just the TRS-80 for $400, most opted for the package that included the twelve-inch monitor and cassette recorder for $600. This example of the object includes the TRS-80 Expansion Interface for $299 (the monitor sits on it) that gave the machine an extra thirty-two kilobytes of memory. Also part of the system are two Mini-Disk drives that sold for $499 and a suitcase for carrying all this around.
One also could purchase such accessories as a TRS-80 Telephone Interface II for $199 that allowed for network communication and printer for $399. Examples of these are in the Smithsonian collections, although they were not received with this specific microcomputer.
This TRS-80 was used by donor Kenneth S. Wiedlitz of Los Angeles, along with the remaining materials in the accession.

Texas Instruments Model 99/4A Microcomputer

When the TI-99/4A was introduced in 1981, Texas Instruments claimed it was both "a major breakthrough in computer technology," and, probably more important, the "lowest priced, 16-bit computer available." It cost only $525.
Description
When the TI-99/4A was introduced in 1981, Texas Instruments claimed it was both "a major breakthrough in computer technology," and, probably more important, the "lowest priced, 16-bit computer available." It cost only $525. The TI 99/4a was a redesign of the TI-99/4 system, which had been a market failure and was discontinued. The new machine sold well, but by August 1982, TI was falling behind its competitors, especially Commodore. So it began offering a $100 rebate on the TI-99/4a. It quickly became the best-selling home computer in America, controlling, by the end of 1982, approximately 35% of the market--150,000 machines a month.
In February 1983, TI cut the price to $150, and then in June 1983, it offered a plastic version of the TI-99/4a for less than $100. But now it had gone too far. It was selling computers for less than cost, resulting in a second quarter loss of $100 million.
The TI-99/4a operated on a TI TMS99000 at 3 MHz and included 16 KB of RAM and 26 KB of ROM. The computer included a RS-232 interface card and a 32K memory expansion card as well as a Data Storage cassette. Texas Instruments controlled the development of software for the machine and offered only around 300 titles. These did not include many of the most popular programs of the time.
Initially, the only way to expand the machine was to use a port on the right side of the console. Peripherals could extend out several feet. To remedy the situation TI released a more convenient Peripheral Expansion Box (PEB) and, surprisingly, sold 250,000 units at $1,475.00 each--far more than the cost of the computer.
Eventually Texas Instruments sold over 2.5 million units of the TI-99/4A. However the company decided that computers were not a promising business and dropped out of the PC market in 1984.
This example of the TI 99/4A was acquired by the donors in 1982. For related objects, see the rest of accession 1990.0494 as well as acquisition 1990.3142.

Description
These oddly cut index cards are actually programs for the very first video games.
These program cards were used with the “Brown Box,” prototype for the first multiplayer, multiprogram video game system. Users of the "Brown Box" could play a variety of games by flipping the switches along the front of the unit. The games included ping-pong, checkers, four different sports games, target shooting with the use of a lightgun and a golf putting game which required the use of a special attachment.
To play these games, the user placed one of these program cards between the two sets of switches on the "Brown Box" (as you can see in the picture). The dots on the card indicated in which position the switches should be set. Magnavox licensed the "Brown Box" and released the system as the Magnavox Odyssey in 1972, with the switch system replaced by a plug-in game slot and plastic program cards.

The Brown Box, 1967–68

This machine paved the way for the video games of today.In 1967, Ralph Baer and his colleagues at Sanders Associates, Inc. developed a prototype for the first multiplayer, multiprogram video game system.
Description
This machine paved the way for the video games of today.
In 1967, Ralph Baer and his colleagues at Sanders Associates, Inc. developed a prototype for the first multiplayer, multiprogram video game system. Since Sanders hoped to license the technology for a commercial venture, Baer understood that the games had to be fun or investors and consumers would not be interested. In an oral history interview (copies available in the Archives Center at the National Museum of American History), Ralph Baer recalled, “The minute we played ping-pong, we knew we had a product. Before that we weren’t too sure.”
Originally called TV Game Unit #7, much like the "Pump Unit" before it, it became far better known by its nickname, “The Brown Box.” The name comes from the brown wood-grain, self-adhesive vinyl used to make the prototype look more attractive to potential investors. The "Brown Box," though only a prototype, had basic features that most video games consoles still have today: two controls and a multigame program system.
The "Brown Box" could be programmed to play a variety of games by flipping the switches along the front of the unit, as can be seen in the picture. Program cards were used to show which switches needed to be set for specific games. "Brown Box" games included ping-pong, checkers, four different sports games, target shooting with the use of a lightgun and a golf putting game, which required the use of a special attachment. Sanders licensed the "Brown Box" to Magnavox, which released the system as the Magnavox Odyssey in 1972.

Texas Instruments SR-10 Handheld Electronic Calculator

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.
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.
