Nuclear Data, Inc.
Nuclear Data Incorporated was a manufacturer of scientific measuring devices for high energy physics laboratories. Application areas included X-ray analysis and radiation monitoring. In the 1960s, they built minicomputers to automate their laboratory devices, such as the ND 812. Over time they replaced these custom designed computers with DEC LSI-11 minicomputers with custom peripherals. Their headquarters were located in Schaumburg, Illinois Schaumburg ( ) is a village mostly in Cook County and partly in DuPage County in northeastern Illinois, United States. Per the 2020 Census, the population was 78,723. Schaumburg is around northwest of the Chicago Loop and northwest of O'Hare I .... In May, 1973, Bunker Ramo acquired the Electronic Store Information Systems Division of Nuclear Data for $3.2 million in cash. The sale included a point of sale terminal business. On July 5, 1989, the company formally changed its name to Metropolitan Circuits, Inc., after having dives ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bunker Ramo
Bunker Ramo Corporation, often shortened to Bunker Ramo, was an American electronics company based in Trumbull, Connecticut. It was founded by George M. Bunker and Simon Ramo in 1964, jointly owned by Martin-Marietta and Thompson Ramo Wooldridge ( TRW). The holdings of Teleregister Corporation became part of the new company. It became a manufacturer of military electronics devices and digital computers including the transistorized BR-133 of 1964, given the military designation AN/UYK-3.http://jproc.ca/rrp/uyk3.html retrieved 2009 Sept 27 It was a supplier of video display terminals to the financial industry. In 1967 the Amphenol corporation (a manufacturer of electrical connectors) merged with Bunker Ramo. The combined company peaked at number 338 on the Fortune 500 list in 1969. In February 1971, the firm unveiled the first version of the National Association of Securities Dealers' Automated Quotations system, NASDAQ.The Wizard of Lies; Bernie Madoff and the Death of Trust, Di ...

Schaumburg, Illinois
Schaumburg ( ) is a village mostly in Cook County and partly in DuPage County in northeastern Illinois, United States. Per the 2020 Census, the population was 78,723. Schaumburg is around northwest of the Chicago Loop and northwest of O'Hare International Airport. It is part of the Golden Corridor. In 2018 ''Money'' magazine ranked the Village of Schaumburg the Best Place to Live in Illinois. In 2017, ''Money'' ranked Schaumburg the 9th-best place to live in the United States. Along with Bolingbrook, Schaumburg has one of Illinois's two IKEA stores. It contains the Woodfield Mall, the 10th largest mall in the United States, which at most times has over 300 stores. Schaumburg's transition from a rural community to a suburban city began with Alfred Campanelli's first large-scale suburban-style development in 1959 and Woodfield Mall's opening on September 9, 1971. Schaumburg is bordered by Hoffman Estates and Palatine to the north, Inverness in northwest, Rolling Meadows to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ND812
The 12-bit ND812, produced by Nuclear Data, Inc., was a commercial minicomputer developed for the scientific computing market. Nuclear Data introduced it in 1970 at a price under $10,000 (). Description The architecture has a simple programmed I/O bus, plus a DMA channel. The programmed I/O bus typically runs low to medium-speed peripherals, such as printers, teletypes, paper tape punches and readers, while DMA is used for cathode ray tube screens with a light pen, analog-to-digital converters, digital-to-analog converters, tape drives, disk drives. The word size, 12 bits, is large enough to handle unsigned integers from 0 to 4095 – wide enough for controlling simple machinery. This is also enough to handle signed numbers from -2048 to +2047. This is higher precision than a slide rule or most analog computers. Twelve bits could also store two six-bit characters (note, six-bit isn't enough for two cases, unlike "fuller" ASCII character set). "ND Code" was one such 6-bit ...

Digital Equipment Corporation
Digital Equipment Corporation (DEC ), using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until forced to resign in 1992, after the company had gone into precipitous decline. The company produced many different product lines over its history. It is best known for the work in the minicomputer market starting in the mid-1960s. The company produced a series of machines known as the PDP line, with the PDP-8 and PDP-11 being among the most successful minis in history. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space. As microcomputers improved in the late 1980s, especially wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
