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

Timex Sinclair 2068 Personal Computer
- 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.

NorthStar Horizon Personal Computer
- 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.

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.

Apple Macintosh Personal Computer
- Description
- The Apple Macintosh 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 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. 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.

Apple II Personal Computer
- Description
- In 1976, computer pioneers Steve Wozniak and Steve Jobs began selling their Apple I computer in kit form to computer stores. By August of that year, Wozniak started designing an improved version, the Apple II. Wozniak and Jobs demonstrated a prototype in December, and then introduced it to the public in April 1977. The Apple II started the boom in personal computer sales in the late 1970s, and pushed Apple into the lead among personal computer makers.
- The Apple II used a MOS 6502 chip for its central processing unit. It came with 4 KB RAM, but could be extended up to 48 KB RAM. It included a BASIC interpreter and could support graphics and a color monitor. External storage was originally on cassette tape, but later Apple introduced an external floppy disk drive. Among the Apple II's most important features were its 8 expansion slots on the motherboard. These allowed hobbyists to add additional cards made by Apple and many other vendors who quickly sprung up. The boards included floppy disk controllers, SCSI cards, video cards, and CP/M or PASCAL emulator cards.
- In 1979 Software Arts introduced the first computer spreadsheet, Visicalc for the Apple II. This "killer application" was extremely popular and fostered extensive sales of the Apple II.
- The Apple II went through several improvements and upgrades. By 1984, when the Macintosh appeared, over 2 million Apple II computers had been sold.

IBM PCjr Personal Computer
- 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 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. IBM discontinued the PCjr in March of 1985 after selling only approximately 270,000 units.

Franklin Ace 1200 Personal Computer
- Description
- The Franklin Ace 1200 was one of the Franklin Corporation models of Apple II clones made for sale in the United States. It was an upgrade of the Franklin 1000. It was compatible with Apple II computers, but could also run the CP/M operating system.
- The Franklin ACE 1200 had a MOS/Commodore 6502 microprocessor that ran at 1 MHz. It contained 48 KB of RAM and 16 KB of ROM and dual 5 ¼" floppy drives. The Ace 1200 came out between Apple II+ and the Apple //e. It included a CP/M card, a disk controller card, an 80 column card, and a dual serial/parallel card that was software interchangeable. The printer card caused problems because many applications did not recognize it.
- The Franklin Ace 1200 was introduced in 1983 for the price of $2,200. The Franklin series was ended after Franklin lost a legal battle with Apple.
