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.

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.
