The IBM 1401 is a variable-wordlength decimal computer that was announced by IBM on October 5, 1959. The first member of the highly successful IBM 1400 series, it was aimed at replacing unit record equipment for processing data stored on punched cards and at providing peripheral services for larger computers. [1] The 1401 is considered by IBM to be the Ford Model-T of the computer industry due ...
The IBM 1401 also struck a creative chord. It was used to craft some of the first crude computer-generated images made up of the letters X and 0 and produced by the 1403 printer. Musician Jóhann Jóhannsson and choreographer Erna Ómarsdótti, whose fathers were IBMers, devised a musical dance piece, "IBM 1401, A User's Manual," in 2007.
Learn about the IBM 1401, the first affordable general-purpose computer announced in 1959, and its features, applications, and history. See photos, specifications, and anecdotes of the 1401 and its peripherals.
We've all heard it: "Today, your phone has a zillion times more processing power than giant computers that filled an entire room in days past!" Rather than review bits and bytes, let's look at CHM's 1401 computer from the point of view of what it can do, and its long-lasting impact on the development of business computing.
Learn about the history and features of the IBM 1401 Data Processing System, one of IBM's earliest transistorized computers that transitioned thousands of businesses and institutions to stored-program computing. The article covers its origins, market success, restoration project, and cultural impact.
The IBM 1401 was a small mainframe introduced by IBM in 1959. It was internally a digit/ character at a time machine (a serial computer, in a way), using decimal addressing; it supported from 1,400 up to 16,000 locations of main memory.
The IBM 1401's ISP was the first to be adopted by another 01 ISP. The ISP of the H-200 is more complex and increases performance by organizing Mp by both characters an words. The IBM 1401, 1440, and 1460 are the only IBM computers to be completely character-string o
The IBM 1401 Data Processing System—comprising a variety of card and tape models with a range of core memory sizes, and configured for stand-alone use and peripheral service for larger computers—was announced in October 1959. Branscomb's group set a target rental cost of US$2500 per month, well below a 700 series machine, and hit it.
The IBM 1401, introduced in 1959 was one of the first widespread computer mainframes, with an estimated half of the world computers being IBM 1401 by the mid 1960's. This period marketing video does a great job presenting its main features, if you can bear following the subtitles. Even though it is enormous and hugely expensive by today's standards, it ushered a new area of "small" and ...
The 1401 was a small character machine with variable word length. It was intended to replace installations of punched card equipment. Originally available with 1400 to 4000 characters of memory, a later external core unit was developed for up to 16 000 characters. The cycle time was 11.5 microseconds per character. class: The IBM 1400 Series class IBM 1401: IBM 1401 system for IBM 1401: FSU ...
