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

Remington Rand Univac Minimum Latency Calculator Slide Rule
- Description
- This circular device was an aid to programming the UNIVAC solid state computer. It consists of a paper disc, with equal divisions running from 1 to 200 near the edge, and a clear plastic rotating disc. These are pivoted together at the center. The upper disc is marked in red with two perpendicular diameters. The lower disc is marked: MINIMUM LATENCY CALCULATOR FOR THE UNIVAC SOLID-STATE COMPUTER. The UNIVAC had a magnetic storage drum on which locations were specified numerically. The latency calculator allowed programmers to write code for the machine to make the most efficient possible use of the drum memory.
- The back of the instrument gives a list of instruction codes and corresponding execution times for words. It is marked: Remington Rand Univac. It is also marked: U1767 Rev. 1 PRINTED (/) IN (/) U.S.A. The rule was received in a paper bag.

Blackberry Model R900M
- Description
- The Blackberry is a handheld wireless Personal Data Assistant (PDA) and communication device. It has a thumb keyboard and a wheel for navigation, as opposed to using a stylus like its competitors. This unit was owned by a law firm partner who arrived at the World Trade Center on September 11, 2001, just minutes after the first tower was hit. Using this Blackberry, he stayed in constant communication with his staff all day until he had located everyone.
- Blackberry devices were also instrumental in the publication of the Wall Street Journal on September 12, 2001. Although their offices were vacated and their staff scattered, WSJ writers were able to use their Blackberrys to write stories and submit them to editorial staff as events unfolded on September 11th.

Hammond Multiplex Typewriter
- Description
- This Hammond Folding Multiplex typewriter was manufactured by the Hammond Typewriter Company of New York beginning in 1923. The typewriter uses Hammond’s patented type-shuttle and hammer typing mechanism where the printing is done by a hammer in the back of the machine striking a type-carrying shuttle in the front of the machine, with the paper and ink ribbon in between to receive the impression. This Hammond Folding Multiplex contains two additional Hammond innovations. It is called a Multiplex because the typewriter contains two type shuttles that can easily be rotated into use, allowing the typing of two complete alphabets in different typesets on each machine. This typewriter’s keyboard could also fold up to allow a cover to be attached to the base, allowing the typewriter to be carried. The keyboard is in a three row QWERTY array.
- James Bartlett Hammond filed patents for his type-shuttle and hammer typing mechanism present in Hammond typewriters in 1879, receiving patent number 224088 on February 3rd, 1880 and patent number 232402 September 21st, 1880. The Hammond Typewriter Company was founded in 1880, and produced its first machine by 1884, winning a gold medal at the New Orleans Centennial Exposition that same year. The Hammond Typewriter touted its superior strength and durability due to its unique type-shuttle and hammer typing mechanism. The replaceable type-shuttle also contributed to the Hammond’s popularity with the ability to print in a variety of typesets in various sizes, including math formulae, special symbols, and foreign characters with an easy replacement of the type shuttle, or an even simpler rotation of a wheel in the Hammond Multiplex.

New Franklin Typewriter
- Description
- This New Franklin typewriter was manufactured by the Franklin Typewriter Company of New York, New York around 1904. The design for the Franklin typewriter was patented by Wellington P. Kidder, receiving patent number 464,504 on December 8, 1891. The main feature of the Franklin typewriter is its series of radial type bars that carry multiple typefaces. The curved Franklin keyboard remains one of its most distinctive features.
- The Tilton Manufacturing Company of Boston, Massachusetts was originally assigned patents to both the Victor Index Typewriter (invented by Arthur Jacobs in 1889) and the Franklin typewriter (invented by Wellington Kidder in 1891). Eventually, both these typewriters were sold by their own companies, with the Victor Typewriter Company staying in Boston and the Franklin Typewriter Company moving to New York. The Franklin Typewriter Company began producing Franklin Typewriters in 1892, releasing numerous models before the company went bankrupt in 1904. The Victor Typewriter Company of Boston absorbed the interests of the Franklin Typewriter Company in 1907 and moved into its New York factory and offices at 812 and 814 Greenwich Street, producing its new visible frontstriking typewriter Victor No.1 that same year.

Slide Rule, Minimum Latency Calculator for the UNIVAC Solid-State Computer
- Description
- This circular device was an aid to programming the UNIVAC solid-state computer. It consists of a paper disc with equal divisions running from 1 to 200 near the edge, and a clear plastic rotating disc that are pivoted together at the center. The upper disc is marked in red with two perpendicular diameters. The solid state computer had a magnetic storage drum on which locations were specified numerically. The latency calculator allowed programmers to write code for the machine to make the most efficient possible use of the drum memory. The back of the instrument gives a list of instruction codes and corresponding word times. Recieved in bag. Reference: Sperry Rand Corporation, Programming: Simple Transition to Electronic Processing UNIVAC Solid-State 80, 18-26.
- Compare 2005.0271.01. Date based on date of documents 2015.3097.03 and 2015.3097.04.
- According to Kirk Lubbes, who programmed the Univac Solid State Computer:
- "The SS90 had a drum memory, i.e. memory was not random accessible. One had slow memory and fast memory. The slow memory had only a single read/write head per track on the drum and fast memory had four read/write heads spaced at 90 degrees, so therefore the drum had to rotate a full revolution to access a memory word in slow memory and only a quarter turn to access fast memory.
- The trick in programming the SS90 was to have the instruction and its operand accessible at an optimal time so that the instruction could access its operand without waiting for the drum very far. As one started a program, this was not much a problem. The programmer new how much time that a given instruction would take to execute and the speed of the drum. Therefore, he calculated the position of the next instruction, based these two parameters. The minimum latency calculator was a mechanical device to help in this calculation. The problem was that as the programmer progressed, collisions occurred, i.e. the optimal location of an instruction or an operand was already taken by a previous instruction or operand. Since the drum was arranged in bands and the read/write heads were at the same location on each band, if one had a collision, you could put the necessary instruction or operand in a parallel band at the same position. This worked the bands all filled up.
- The basic approach was to get a program working using the best latency that you could. Then the programmer would go back and start rearranging instructions and operand locations to achieve minimum latency. In those early times, machine time was expensive and memory severely limited. So it was important that production programs were efficient."
