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

National Semiconductor Mathematician Handheld Electronic Calculator

In addition to selling calculators under the Novus name, National Semiconductor Company sold models with the same capabilities but somewhat different styling under its own name.
Description
In addition to selling calculators under the Novus name, National Semiconductor Company sold models with the same capabilities but somewhat different styling under its own name. This handheld electronic calculator has the same capabilities as the Novus Mathematician.
The calculator has a black plastic case, thirty-two rectangular plastic keys, and a plastic display cover. The function of the keys is written on the keyboard rather than being marked on the keys themselves.
At the bottom of the keyboard are ten digit keys, a decimal point key, and a clear key. To the right of these is a column of four arithmetic function keys. Depressing the F key in the upper left corner of the keyboard allows two of these keys to be used as memory keys, another for entering degrees, and the fourth for entering radians.
Above these keys are an enter key and a variety of function keys, some of which also can assume more than one function. These include two memory keys, a change sign key, a pi key, a square root / square key, a log key, an exchange key, a power key, an exponent key, a natural log key, an inverse key, and keys for trigonometric and inverse trigonometric functions. A mark above the keyboard reads: Mathematician.
Problems are entered into the Mathematician using reverse Polish notation.
Behind the keyboard is an eight-digit red LED display. It has no provision for displaying results in scientific notation. A mark above the display reads: National Semiconductor. The jack for a power adapter is along the back edge and a power switch is on the left edge.
A battery compartment opens on the back of the calculator. A faint mark molded into the plastic near the top of the back reads: MADE IN MALAYSIA (/) P641. This particular example lacks both a cover for the battery compartment and any stickers identifying the model and serial number.
Compare the Novus Mathematician (1986.0988.277) and the HP-21 (1987.0435.08).

Description
In 1975, Novus, the Consumer Products branch of National Semiconductor Corporation, introduced a series of handheld electronic calculators known as the “Professionals.” As a June 1975 advertisement in the Chicago Tribune put it, these were designed to fill the gap between “very expensive calculators offering every feature in the book” and “‘Mickey Mouse’ models which were much less costly, but which just didn’t have what it takes to do the job.” The least expensive of these calculators was The Mathematician, which initially sold for $69.95. Others in the series included the Programmable Mathematician, The Financier, The Programmable Financier, The Statistician, The Programmable Statistician, and The International Computer (later sold as The International Converter). By 1976, Novus had also introduced The Scientist and The Programmable Scientist.
This is an example of the Novus Statistician. The calculator has a tan plastic case, thirty-two rectangular plastic keys, and a plastic display cover. At the bottom of the keyboard are ten digit keys, a decimal point key, and a clear key. To the right of these is a column of four arithmetic function keys. The function of these keys is marked on the keys themselves.
Above these keys are a total key and a variety of function keys and a clear all key. The function of all but the total key is indicated on the keyboard. A mark above the keyboard reads: Statistician. Behind the keyboard is an eight-digit red LED display. A mark above this reads: NOVUS. The jack for a power adapter is along the back edge and a power switch is on the left edge.
A battery compartment opens on the back of the calculator. A sticker on the compartment cover reads in part: BATTERY/ADAPTER (/) INSTRUCTIONS. It also reads in part: NOVUS – Consumer Products (/) National Semiconductor Corp. (/) Made in U.S.A. A second sticker on the back gives operating instructions. It reads in part: NOVUS 6030. It also reads in part: Serial No. 1020564.
The object comes with a brown leather felt-lined zippered pouch. A mark on the pouch reads: NOVUS. It contains a plastic card with “statistical key callouts” for the calculator.

Description
In 1975 Novus, the Consumer Products branch of National Semiconductor Corporation, introduced a series of handheld electronic calculators known as the “Professionals.” As a June, 1975, advertisement in the Chicago Tribune put it, these were designed to fill the gap between “very expensive calculators offering every feature in the book” and “‘Mickey Mouse’ models which were much less costly, but which just didn’t have what it takes to do the job.” The least expensive of these calculators was The Mathematician, which initially sold for $69.95. Others in the series included the Programmable Mathematician, The Financier, The Programmable Financier, The Statistician, The Programmable Statistician, and The International Computer (later sold as The International Converter). By 1976, Novus had also introduced The Scientist and The Programmable Scientist.
This is an example of the Novus Scientist. The calculator has a black plastic case, thirty-five rectangular plastic keys, and a plastic display cover. At the bottom of the keyboard are ten digit keys, a decimal point key, and a clear key. To the right of these is a column of four arithmetic function keys. The function of these keys is marked on the keys themselves. Also included among the marked keys is an enter key—the calculator used reverse Polish notation.
To the right and above these keys are a variety of function keys. The function of the keys is indicated on the keyboard. A mark above the keyboard reads: Scientist. Behind the keyboard is an eight-digit red LED display. A mark above this reads: NOVUS. The jack for a power adapter is along the back edge and a power switch is on the left edge.
The calculator has no separate battery compartment. A sticker with instructions on the back (upside down in this case) reads in part: NOVUS 4520. It also reads at the bottom: NOVUS – Consumer Products from National Semiconductor Corp. (/) Made in U.S.A. It also reads: Serial No. (/) 126956. Text on the bottom of the case reads: MADE IN USA (/) U609.

National Semiconductor Quiz Kid Racer, Electronic Game

Quiz Kid Racer is an arithmetic quiz game for one or more children, introduced by National Semiconductor in 1978. According to a Montgomery Ward advertisement published that year, the game was designed for children six years old and up.
Description
Quiz Kid Racer is an arithmetic quiz game for one or more children, introduced by National Semiconductor in 1978. According to a Montgomery Ward advertisement published that year, the game was designed for children six years old and up. It presented problems in addition, subtraction, multiplication, and division at different levels of difficulty. Questions at the “PRO” level are more difficult than those at the “AMATEUR” level. At the “COMPLEX” level, one number, an operation, and the answer are given – the child provides the other number. Problems also can appear as tables. Pressing the correct answer causes a green light to the right of the display to light up. After an incorrect answer, a child was allowed another try, after this the correct answer appears in the display. Two children also could play the game competitively using two copies of the game.
The object has a white plastic case with a brightly colored sticker as the keyboard. The game has twenty rectangular plastic keys. These include ten digit keys, four operation keys, four keys for setting the level of the game, a “SLOW” key, and a “FAST” key. The on/off switch is above the keys. A mark above it reads: National (/) Semiconductor. A mark right of the keys reads: Racer. A mark above the display reads: QuizKid.
The battery compartment is at the top of the back, and a power adapter can plug into the back edge. A mark stamped on the back reads: MADE IN HONG KONG. Prices ranged from $19.99 down to $9.99.
Compare the Little Professor made by Texas Instruments (see 1986.0988.197), as well as the Whiz Kid (1986.0988.307), the Quiz Kid Speller (1986.0988.235) and the Quiz Kid (1988.0988.237).
