Computers & Business Machines - Overview

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. 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. Other artifacts range from personal computers to ENIAC, the Altair, and the Osborne 1. 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

Commodore PET 2001 Personal Computer
- Description
- In 1977, Commodore introduced the PET (Personal Electronic Transactor) home/personal computer. Appearing before either the Apple II or the Radio Shack TRS80, it was among the first personal computers. The PET 2001, Commodore's first model, included 4 kilobytes of memory, cost $495, and was fully functional out the box. The computer sold well, but initially Commodore could produce only a meager 30 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.

Texas Instruments Model 99/4A Personal Computer
- 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.

MITS Altair 680 Kit Computer
- Description
- The Altair 680 appeared about a year after Micro Instrumentation and Telemetry Systems (MITS) had introduced the Altair 8800, which many historians credit as the beginning of the home computer industry. In the Altair 680, MITS offered an update of the Altair 8800 that was based on the Motorola 6800 processor.
- Like the Altair 8800, the Altair 680 was a kit. For $293, users received circuit boards, capacitors, resistors, transistors, diodes, a power supply, an instruction manual, and a case in which to assemble it. Also like the 8800, the 680 had switches on the front that could be used to enter computer instructions, bit by bit. If customers were willing to pay $420, they could buy the computer already assembled. Neither the kit nor the assembled computer came with display, keyboard, or external storage device.
- The Motorola 6800 microprocessor ran at 500 KHZ, and the computer had a 1 KB of RAM and 1 KB of ROM, as well as support for a serial terminal and punch reader.
- The Altair 680 did not meet with the success that the 8800 had. Most users were now interested in buying computers that came with displays and keyboards, and were willing to pay more for them. The Altair 680 kit in the Smithsonian was never assembled.

Timex Sinclair 2068 Personal Computer
- Description
- Introduced in 1983 at a cost of $199.95, the Timex-Sinclair 2068 (TS 2068) was the Timex Sinclair's fourth and last personal computer for the US market. It followed the ZX81, TS 1000, TS 1500, and the ZX Spectrum.
- The TS 2068 used a Z80 processor that ran at 3.58 MHz. Its memory included 48 KB of RAM and 54 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 2400 printer that was attached to an expansion port.
- The TS 2068 was well equipped for playing games and was compatible with all software designed for the ZX Spectrum. The computer was generally used for entertainment, educational, and programming tutorials.

Commodore Plus/4 Personal Computer
- Description
- Commodore International announced the Commodore Plus/4 in January 1984 as the Commodore 264. It was a more powerful sequel to the highly successful Commodore 64. The original concept was to sell the 264 in one of several different configurations. The consumer would select the type of application software they wanted to build in their computer, and the dealer would install the appropriate ROM chip. By the summer of 1984 this concept was abandoned. The name was changed to Plus/4, the computer was sold at the cost of $299, and all applications were added at the factory.
- The Plus/4 was billed as the: "productivity computer with software built in." The Plus/4 has a MOS processor which ran at 1.76 MHz. It contained 64 KB of RAM and 64 KB of ROM. The Plus/4 had a built in MOS Technology 6551 UART chip which allowed the Plus/4 to use high speed modems without additional software. The computer included Commodore BASIC 3.5 and such software applications as a word processor, spreadsheet, database, and graphing. Inclusion of these four applications led to the computer being called the "Plus/4."
- The machine was discontinued in 1985 when it failed to achieve the company's sales goals.

Commodore Amiga 500 Personal Computer
- 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 6800 microprocessor that ran at 714 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.

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 Context, 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 3502 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.

Apple Lisa II Personal Computer
- 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.
