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

Tandy 1400 Personal Computer LT

This portable computer, one of the first to be compatible with an IBM-PC, has a tan plastic case, and opens to reveal a screen about the size of the keyboard (and about half the total size of the case).Two disc drives are behind the keyboard.
Description
This portable computer, one of the first to be compatible with an IBM-PC, has a tan plastic case, and opens to reveal a screen about the size of the keyboard (and about half the total size of the case).Two disc drives are behind the keyboard. A heavy AC adapter fits into a jack in the back of the case. The donors reported that this was their daughter's first computer, on which she practiced lessons as a preteen. His son also may have used it to create spreadsheets for the donor's business in the summer of 1989. For software received with the computer, see 2014.0090.02.

Radio Shack TRS-80 Microcomputer Monitor

In the summer of 1977, Radio Shack introduced the TRS-80 for $599. You could purchase the computer without a display for $399.95, but the most common configuration was buying the computer, monitor, and datacassette recorder for $599.

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.

TRS-80 Model 100 Microcomputer

The Tandy/Radio Shack TRS-80 Model 100 was one of the precursors to the modern laptop.
Description
The Tandy/Radio Shack TRS-80 Model 100 was one of the precursors to the modern laptop. The functions were fairly limited but the size and battery power were well recieved.
This computer was actually made by Kyocera, now a brand name recognized worldwide as a manufacturer of popular cell phone and PDA hybrids.
This example of the computer was used by Paul E. Ceruzzi when he was a curator at the Smithsonian's National Museum of American History.
In addition to the computer itself, this index number covers a plastic carrying case for it.

Description
This handheld electronic calculator has a black and charcoal case and an array of eighteen black, white, and red "Klixon" keys. Such keys have a design trademarked by Texas Instruments and make a distinctive click when pressed. In addition to ten digit keys and one decimal point key, the calculator has four keys for arithmetic functions. One serves as a total key for addition and another as a difference key for subtraction. The top of the keyboard has a constant switch, a D key for recalling the display, a clear entry key, and a red clear key. The on/off switch is behind the clear key and the eight-digit red LED display behind this. A cord for recharging the battery attaches at the back of the top (this example has no cord).
The back has four plastic feet (one is missing on this example). A paper sticker there gives operating instructions. Text near the bottom of it reads: RADIO SHACK MODEL EC-200 (/) SER. NO. A2 6411 (/) MADE IN U.S.A.
