Description: In 1977, Commodore introduced the PET (Personal Electronic Transactor) home/personal computer. Appearing before either the Apple II or the Radio Shack TRS-80, it was among the first personal computers. The PET 2001, Commodore's first model, included four kilobytes of memory, cost $495, and was fully functional out the box. The computer sold well, but initially Commodore could produce only a meager thirty units a day.; The PET had a main board with a 1 MHz MOS 6502 processor and room for additional RAM. The machine included a built-in cassette on the front of the case for data storage. Users could write their own programs in BASIC, but many complained about the small keyboard, which made touch typing difficult. The screen of the PET computer was small (9"), and had a black or blue display. Users could design simple graphics, do animations, or work out math problems. A notable feature of the PET 2001 was that the top of the computer opened for maintenance like the hood of a car.; PET 2001 was designed by computer pioneer Chuck Peddle. He came to Commodore during the company's acquisition of MOS Technology in 1976. AT MOS, he had designed the KIM (Keyboard Input Monitor) computer. At Commodore, he convinced managers that computers were "in" and won approval to design the PET. It paved the way for later Commodore machines, such as the Commodore-64.; This particular PET 2001 was donated by Louis Mittleman, who noted not only that the keyboard was a serious "drawback," but also that the manual did not have much information.

In the early 1980s, Digital Equipment Corporation (DEC) was the second largest computer company in the United States, following IBM, and was the leading producer of minicomputers.

Description: In the early 1980s, Digital Equipment Corporation (DEC) was the second largest computer company in the United States, following IBM, and was the leading producer of minicomputers. DEC had missed the initial development of personal computers, but decided to enter the market with a 16 bit machine. In 1982, it introduced the DEC Rainbow 100, for a price of $2,500.; The Rainbow 100 had both a Z-80 and an Intel 8088 microprocessor that ran at 4 MHz. It had 64 KB or RAM and 24 KB of ROM and had two built in floppy drives that could accommodate 400 KB single-sided quad density disks. It had three operating systems: MS-DOS, CP/M-86, and CP/M. Users made a selection by a menu at boot time. This portion - CPU - sat on a floor stand. For the monitor, see 1994.0078.01.2. For the keyboard, see 1994.0078.01.3. For related documentation, see 1994.3022.; The Rainbow could be used for word processing, spreadsheets, and games, although it had a monochrome screen. In addition to operating as a stand-alone computer, the Rainbow worked effectively as a VT-100 or VT-220 terminal emulator on larger machines, such as DEC's minicomputers. Although the Rainbow was a powerful and effective personal computer, it was not fully compatible with IBM systems, and eventually was overshadowed and undersold by IBM clones.; According to the donor, Steve Lubar, writing at the time he gave the machine to the museum, "purchased the Rainbow 100 in 1984, through my wife, Lisa Thoerle,who was then an employee of Digital Equipment Corporation.There was a large employee discount, perhaps almost 50%,(if I remember right!) which made the machine affordable,and close in price to more common PCs.; At the time,I was employed as a historian in the Department of; History of Science and Technology,working on the Engines of Change exhibition and a variety of scholarly papers. I used the Rainbow for word processing mostly, using WordStar software,and as a VT-100 terminal, using the built-in emulation, to call bulletin boards. I always used the machine in its CP/M mode, mostly because I found; that the only software I had for the MS-DOS mode(an early version of WordPerfect) was dreadful. Lisa used the machine a bit; she had a; C compiler,but found the machine too slow to use to do any serious; work. (She was used to VAXs and PDP-11s).; I used the Rainbow until 1988 or 1989,when I purchased a; Macintosh SE.The Rainbow,it was clear by that point, was a; technological deadend,too expensive to upgrade,and too; idiosyncratic to take advantage of the ever-cheaper prices on; hardware upgrades then available for IBM-standard PCs."; Reference:; Accession File 1994.0078.

After the success of the IBM's business PC, IBM attempted to capture the home market with the IBM PCjr.

Description: After the success of the IBM's business PC, IBM attempted to capture the home market with the IBM PCjr. The PCjr system was compact, low cost, and designed for applications related to learning, entertainment, and personal productivity.; The computer had an Intel 8088 microprocessor that ran at 4.77 MHz–faster than most systems on the market at the time. It had 64 KB of RAM, which could be expanded to 256 KB and later to 720 KB with third party add-ons. It featured an internal 5 1/4" floppy drive and a wireless keyboard. King's Quest, a popular Adventure game of the 1980s, debuted on the PCjr.; Despite a flashy debut and a strong technology core, the PCjr flopped in the market. Consumers were not as attracted by the IBM name as business had been. Price was a major factor. The PCjr cost about the same as the Coleco Adam, but for the price, the Adam included two tape drives, a printer, and software. The PCJr was twice as expensive as the Commodore 64. With the exception of the Apple II, it was possible to purchase a complete system (computer, disk drive, and printer) from almost any of IBM's competitors for less money. However, criticism of the system focused on the "chiclet" keyboard. Similar to that of a pocket calculator, the small keys were cheap and difficult to use for touch typing. IBM later replaced this with a wireless conventional-sized keyboard. But it could only be used two or three feet away from the machine and drained batteries quickly.; Announced in November 1983 and available in March 1984, IBM sold the PCJr for $669 with 64 KB RAM, and $1,269 for 128 KB RAM. The more expensive system also included a floppy-disk drive. The device was manufactured in Lewisburg, Tennesee, by Teledyne, IBM discontinued the PCjr in March of 1985 after selling only approximately 270,000 units.

The Apple Lisa introduced the graphic user interface (GUI) into the Apple Computer Corporation's line of personal computers. Instead of using only text-based commands, users could employ pictorial icons displayed on the screen to initiate operations.

Description: The Apple Lisa introduced the graphic user interface (GUI) into the Apple Computer Corporation's line of personal computers. Instead of using only text-based commands, users could employ pictorial icons displayed on the screen to initiate operations. Officially, "Lisa" stood for "Local Integrated Software Architecture," but it was also the name of Apple co-founder Steve Jobs' daughter. This computer was also Jobs "baby," as he championed its creation and believed it would revolutionize personal computing. Apple spent four years and $50 million to develop it, but it turned out to be a commercial flop, in large part because of the $10,000 per unit cost. Only 80,000 were eventually sold. The Lisa is most important historically as the computer that pioneered concepts later used in the far more successful Macintosh.; This Lisa has model number A65B100 and serial number B08B832370482. It was owned and used by Roslyn Lang and her family. Her husband used it for academic work, while she and her children used it for computer games. She said: "As I recall, these were mainly games that you played against the software by looking at pictures of a castle and trying to free the princess without being eaten by an ogre!”

Description: In 1987, Commodore introduced the Amiga 500, also known as the A500, as an inexpensive version of a 16 bit multimedia home computer. The goal was to provide a machine that would compete successfully against other 16 bit machines, just as the Commodore 64 had outsold many competitive 8 bit computers. The A500 did sell well against the Atari 520ST and was the low end successor of the Amiga 1000.; The A500 used a Motorola 68000 microprocessor that ran at 7.14 MHz and had 256 KB of ROM and 512 KB of RAM, which was expandable to 9MB. The Amiga 500 used a special system for its RAM configuration. It had 512 KB of Chip RAM, which could be accessed by the sound and video custom chip, and FAST RAM, which could only be accessed only by the CPU.; The Amiga 500 was followed by the Amiga 500+. It doubled the amount of the A500s Chip RAM to 1 MB. Both versions could be connected to a TV set or to a video monitor. The A500 computers were the best selling in the Amiga series. Besides doing well in the United States, they also were popular in Europe. Many users favored the Amiga because, in addition to being inexpensive, it had excellent graphics and sound capability for a computer of its era.

Description: Introduced in 1983 at a cost of $199.95, the Timex-Sinclair 2068 (TS 2068) was the fourth and last Sinclair personal computer sold in the US market. It followed the ZX-81 (marketed by Sinclair Research through an American branch), TS 1000, and TS 1500. It’s design also drew on Sinclair’s ZX Spectrum (the Spectrum was not marketed in the U.S.).; The TS 2068 used a Z80 processor that ran at 3.58 MHz. Its memory included 48 KB of RAM and 24 KB of ROM. A cassette recorder was used for external storage. Like the TS 1000, the 2068 included a BASIC interpreter to run programs. Additional functions had been added to handle more complex graphic and sound commands. The TS 2068 included a sound chip and speaker at the bottom of the computer and had a range of 10 octaves and 130 semitones directly programmable from BASIC. Users could buy a TS 2040 printer that was attached to an expansion port.; The TS 2068 was well equipped for playing games and, with the use of an appropriate cartridge, could be used with most software designed for the ZX Spectrum. The computer was generally used for entertainment, educational, and programming tutorials.

The computers in the Apple II family were among the most popular personal computers in the late 1970s and 1980s. The last model and most impressive of the Apple II family was the Apple II GS (GS=graphics + sound).

Description: The computers in the Apple II family were among the most popular personal computers in the late 1970s and 1980s. The last model and most impressive of the Apple II family was the Apple II GS (GS=graphics + sound). When it was released in September of 1986—Apple's 10th anniversary—at the price of $999 (without a monitor—or $1498 with an RGB monitor), the Apple II GS competed against other computers such as the Commodore Amiga and the Atari ST.; The Apple II GS used the Western Design Center 65816 16 bit microprocessor, which ran at 2.8 Mhz. It had 256 KB of RAM, which could be expanded to 8 MB. There were seven slots to accommodate an expansion of memory. It was the first computer to utilize the Apple Desktop Bus (ADB) which linked standard input device such as keyboards, mice, and graphics tablets. This made it possible for Apple to sell a single set of peripherals that both the Apple Computer and later the Macintosh could use. The IIGS display had a 600 X 200 pixel mode with 2-bit palletized cooler and a 320 X 200 pixel mode with a 4-bit palletized color. The Apple II GS could display 256 colors on the screen. Its ProDOS 16 as system software allowed users to handle any number of open files at the same time.; The IIGS seemed well positioned to capture a large market. However, by the time it was released, Apple was putting its energy into developing the Macintosh and the IIGS suffered from limited marketing. Apple discontinued the line in December 1992.; This example of the Apple IIGS is model number A26000, Serial number A2S2-E80113DA2S6000. For related documentation, see 1998.3062.

Kaypro was a manufacturer of portable microcomputers running the CP/M operating system. Its first commercial model, Kaypro II, was launched in 1982. The Kaypro IV was introduced in 1983.

Description: Kaypro was a manufacturer of portable microcomputers running the CP/M operating system. Its first commercial model, Kaypro II, was launched in 1982. The Kaypro IV was introduced in 1983. Surprisingly, it is not the same as the Kaypro 4, which was released in 1984.; The Kaypro IV was basically a Kaypro II with added Double Sided/Double Density Drives. It had a Z80 microprocessor that ran at 2.5 MHz. The memory included 64 KB of RAM and 2 KB of ROM. Kaypro IV had a 9" monochrome monitor and a built-in speaker. The operating system was CP/M 2.2. The Kaypro IV included the word processor Wordstar, which was included in the Perfect Software Suite.; The introduction of the IBM PC in 1981 led to the rapid growth in popularity of the MS-DOS operating system for personal computers. Software developers migrated to writing for MS-DOS instead of CP/M. Kaypro was slow to make the transition in their machines, and the company never gained the kind of prominence in the MS-DOS arena that it had enjoyed with CP/M. A prime competitor for the MS-DOS portable market was Compaq, which sold an "all in one" computer that was similar to its own CP/M portable. In March 1990 Kaypro filed for bankruptcy.; This Kaypro IV was purchased with funds from a research grant obtained by Robert M. Smith, of the Department of Space History of the National Air and Space Museum. Smith's book, The Space Telescope, was written in part on this computer. The object was received as a transfer from the Natonal Air and Space Museum.

Description: Northstar developed from a computer store called "The Original Kentucky Fried Computer." It changed its name due to impending litigation by Kentucky Fried Chicken. The company's first product was a Floating Point Math Board for S-100 computers. They then developed an inexpensive floppy drive system. This led the way to the Horizon, one of the first computers with built in floppy drives.; Announced in November 1977, the Horizon was sold in a wooden cabinet, as opposed to the more usual metal or plastic. The initial price was $1,899 assembled and $1,599 unassembled. The Horizon ran on a Z-80 microprocessor that ran at 4 MHz. It contained 16 KB of RAM, which could be expanded to 64 KB and 1 KB of ROM. The operating system was both CP/M and Northstar DOS. The machine was among the first to offer floppy drives, and customers could order one or two 90 KB 5 ¼" drives. Northstar was also one of the first machines to offer a hard disk drive. This was called an HD-18, and had 18 megabytes on an 18" platter. The Northstar Horizon was suited for business, education, and software development applications.; This particular machine was donated to the Smithsonian by Peter A. McWilliams. He used it in writing The Word Processing Book: A Short Course in Computer Literacy (1982). When it sold well, McWilliams wrote The Personal Computer Book, (1983), which became a runaway bestseller. This was his first computer.

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.

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.

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.; Compare 1986.0988.351, 1986.0988.354, and 1986.0988.356.; References:; Guy Ball and Bruce Flamm, The Complete Collector’s Guide to Pocket Calculators, Tustin, CA: Wilson/Barnett, 1997, p. 153.; The online Datamath Museum includes versions of the SR-10 from 1972, 1973, and 1975.

Description: What do you do after you invent the video game? Try to make it better!; While preparing their video game system prototype, the “Brown Box” to be presented to potential investors, Ralph Baer and his colleague Bill Harrison created TV Game Unit #8. They wanted to demonstrate a more advanced technology that would allow the user’s paddle to determine, in the direction and speed of the game ball, when the two would collide. This would allow for games such as baseball and more realistic hockey game play.; This TV Game Unit #8 interfaced with the "Brown Box," but proved too expensive to pursue in these early stages. Since it was not going to be shown to investors just yet, it was never covered with brown wood grain self-adhesive vinyl to match the "Brown Box." A few years later, this technology was key when Baer and his colleagues started to design and build arcade games.

Description: From this assemblage of metal, wires and glass tubes, the future of video games would be built.; In 1966, while working for Sanders Associates Inc., engineer Ralph Baer began to look into new ways to use television, focusing specifically on interactive games. In 1967, he created the first of several video game test units. Called TVG#1 or TV Game Unit #1, this device, when used with an alignment generator, produced a dot on the television screen that could be manually controlled by the user. Now that he was able to interact with the television, Baer could design increasingly sophisticated interfaces and programs.; TV Game Unit #1 was designed by Baer and built with the assistance of Bob Tremblay, a technician who worked with Baer at Saunders. Though transistors were available, Baer, who had received his bachelor’s in television engineering, choose to use the familiar and proven technology of vacuum tubes for this early test unit.; Like all the Ralph Baer prototypes, TV Game Unit #1 was used as evidence in many patent infringement cases. It still bears many of the court exhibit labels left over from these trials, as may be seen from the photograph.

Description: Ralph Baer is best known for developing the first video games, but he has accomplished more than that.; In 1975, Baer, an engineer and inventor, started an independent consulting business and began to work in association with Marvin Glass & Associates in Chicago, the toy design firm responsible for some of the most successful American toys of the 20th century. Baer’s job was to develop electronic toys and games. The best-known result of this partnership was Simon.; In light of Simon’s success, Baer was asked by Marvin Glass to create another electronic game that was similar in nature. The result was Maniac, which was released by Ideal Toy Company in 1979. It was a multiple-player, sound-based game that required quick reflexes and the ability to identify and recall tonal sequences (rather than merely repeating them as they had with Simon). In an oral history interview (audio copies available in the National Museum of American History’s Archives Center), Baer admitted that the game was “really hard to play. You have to want to play games to want to play Maniac.” This could be the reason that Maniac never matched the popularity of Simon.

Description: This ordinary piece of test equipment played an important role in video game history.; In 1966, while working for Sanders Associates, Inc., engineer Ralph Baer began to look into new ways to use television, focusing specifically on interactive games. Baer had received his bachelor’s in television engineering and was familiar with television test equipment that could meet his needs while keeping cost down. This Heathkit IG-62 Color Bar and Dot Generator, which was used to adjust television sets, provided the key circuitry needed to create an image on a television screen. This allowed Baer and his colleagues to devote their time and attention to develop a way for anyone to be able to move that image.; In 1967, Baer created the first of several video game test units. Called TVG#1 or TV Game Unit #1, the device, when used with an alignment generator like the Heathkit IG-62, produced a dot on the television screen that could be manually controlled by the user. Once they were able to interact with the television, Baer and his team could design increasingly sophisticated interfaces and programs.

Description: The Father of the Video Game was also the inventor of Simon.; Inventor Ralph Baer is best known for developing the first video game system, but he accomplished far more. In 1975, Baer started an independent consulting business and began to work in association with Marvin Glass & Associates in Chicago, the toy design firm responsible for some of the most successful American toys of the 20th century. Baer’s job was to develop electronic toys and games. The best-known result of this partnership was Simon.; Named for the children’s game of “Simon Says,” the game was inspired by an Atari arcade game called Touch Me. Baer and Howard Morrison, a partner at Marvin Glass, first saw Touch Me at a trade show in 1976. Both agreed that while the execution of the arcade game was horrible, the game itself—trying to repeat a musical sequence the machine created—was worthy of exploration. The two set about creating a handheld game around the same concept.; Like Touch Me, Simon had four different colored buttons. Each button played a unique note. Players had to be able to repeat an increasingly long string of tones that Simon created. If you got the order wrong, you lost. Baer was aware that choosing Simon’s four tones was a critical decision. He and Morrison both felt that one of Touch Me’s main failings was that its sounds were unpleasant.; But how to choose four notes that could be played in any sequence and not hurt the ears? Baer found the answer while looking through his children’s Compton's Encyclopedia. He discovered that the bugle can only plays four notes. So, Simon would play those same four bugle notes.; Simon was released by Milton Bradley in 1978 with much fanfare, including a midnight release party at Studio 54, the elite disco in New York City. An instance success, the game reached its peak during the 1980s and continued to sell for decades thereafter.; Baer was very careful to document in his patent application that Simon was based on Atari’s Touch Me, given his past history with the company. Years earlier, Atari was sued for patent rights infringement. At the center of the controversy were the video game prototypes invented by Ralph Baer. With Simon, Baer found himself on the other side of the story. His patent was to protect his innovations, rather than an original game idea.

When most people think about the first video game, they think of Pong, the ping-pong arcade game released by Atari in 1972. However, months earlier, Magnavox had released its Magnavox Odyssey, a home video game system based on the “Brown Box,” a prototype invented by Ralph Baer.

Description: When most people think about the first video game, they think of Pong, the ping-pong arcade game released by Atari in 1972. However, months earlier, Magnavox had released its Magnavox Odyssey, a home video game system based on the “Brown Box,” a prototype invented by Ralph Baer. Additional games and accessories, like a lightgun, were sold in separate packages.; Since the Odyssey had limited graphic capabilities and displayed only a few small white blocks and a vertical line on the screen, Magnavox included translucent color overlays to provide settings and layouts for the games. Perhaps most surprising to modern gamers, the Odyssey also came with nonelectronic game accessories such as dice, decks of cards, play money, and poker chips. These accessories were possibly included to make the Odyssey more like the physical games that existed at the time.; With approximately 350,000 units sold, Magnavox Odyssey was not considered a commercial success, especially in comparison with Pong’s runaway popularity. Among the contributing factors, poor marketing played a large role. Many potential consumers were under the impression—sometimes encouraged by Magnavox salesmen—that Odyssey would only work on Magnavox television sets. Despite these setbacks, Magnavox Odyssey made its mark by starting the video game console industry.

Description: This strange-looking contraption was actually used to play an early video game.; To play the golf game on the “Brown Box,” a prototype for the first multiplayer, multiprogram video game system, Baer and his colleagues mounted a golf ball on a joystick handle. This allowed the player to use a real golf club to practice his or her putting skills. Magnavox licensed the "Brown Box" and released the system as the Magnavox Odyssey in 1972. Though it was never produced commercially, the golf accessory was covered with brown wood-grain, self-adhesive vinyl so that it would match the "Brown Box."

Description: The first video games were played on this machine.; With the use of changing screen color and moving dots, TV Game Unit #2 allowed two players to compete against each other in seven different games. These games included a variety of chase games, a target-shooting game, and games that required the wooden handle attached to the unit’s lower right hand corner (see photograph). The handle was moved up and down, like a pump, in the course of certain games. In honor of this unusual game play, TV Game Unit #2 was rechristened “The Pump Unit.”; Baer and his team demonstrated the "Pump Unit" to Sanders senior management on June 15, 1967. The presentation was successful and now the team had a new goal: to turn this technology into a commercially viable product. After a few years and numerous test and advancements, Baer and his team delivered the “Brown Box,”[hyperlink] a prototype for the first multiplayer, multiprogram video game system. It would be licensed to Magnavox, who released the system as the Magnavox Odyssey in 1972.; Like all the Ralph Baer prototypes, the "Pump Unit" was later used as evidence in many patent infringement cases. It still bears many of the court exhibit labels left over from these trials, as can be seen from the photograph.

Description: The Apple Macintosh microcomputer introduced a graphic user interface (GUI) to the Apple line of computers. The idea had originated at Xerox's Palo Alto Research Center in the 1970s, but Xerox was slow to commercialize it. Apple proved far more successful when it introduced the Macintosh in January 1984, with a splashy television advertisement during the Superbowl. The original price was around $2,500.; Instead of typing out names of programs on command lines, users with a GUI could click "icons," or pictures that represented the programs they wanted to run. They could also execute functions like saving, moving, or deleting files by clicking and dragging the icons around the screen with a pointing device called a mouse. Apple's version of the mouse had a single button, which became an Apple standard. The first Macintosh, exemplified by this object, had only 128K RAM, and users quickly found this insufficient. The Macintosh 512 KB, nicknamed "Fat Mac," was introduced in September 1984. It gave users four times as much memory, and allowed them to keep several major programs open simultaneously (for an example of this machine see 1985.3011.01). The vertical processor case and 9" monochrome screen were distinguishing features of all the early Macintosh line.; The Macintosh 512 KB contained a Motorola 68000 microprocessor which ran at 8 MHz. It contained 512 KB of RAM and 64 KB of ROM and initially had a 400 KB Floppy disk drive. Applications included MacWrite, a word processor, and MacPaint, a drawing program that turned the mouse into a paintbrush. Shortly after the 512 KB appeared, Apple also introduced a LaserWriter printer, which enabled desktop publishing for individuals and small businesses. Over time, Apple computers would appeal most strongly to artists and designers, while the IBM/DOS line of computers sold better in business markets.; After selling hundreds of thousands of units, Apple discontinued the "Mac Classic" line of computers in April 1986.
