IBM 604
The IBM 604 Electronic Calculating Punch was the world's first mass-produced electronic calculator along with its predecessor the IBM 603.IBM 603 The First Commercial Electronic Calculator IBM History, accessed September 21, 2020] It was an electronic unit record equipment, unit record machine that could perform multiple calculations, including division. It was invented and developed by Ralph Palmer, Jerrier A. Haddad, Jerrier Haddad and Byron Phelps. It was introduced by IBM in 1948. It could read a punched card from a deck, do some calculations based on the wiring of its plugboard, and punch results onto the same card. A separate IBM 521 Card Read/Punch processed the cards and had its own plugboard which selected the columns to be read and those to be punched.

Fixed-point Arithmetic
In computing, fixed-point is a method of representing fractional (non-integer) numbers by storing a fixed number of digits of their fractional part. Dollar amounts, for example, are often stored with exactly two fractional digits, representing the cents (1/100 of dollar). More generally, the term may refer to representing fractional values as integer multiples of some fixed small unit, e.g. a fractional amount of hours as an integer multiple of ten-minute intervals. Fixed-point number representation is often contrasted to the more complicated and computationally demanding floating-point representation. In the fixed-point representation, the fraction is often expressed in the same number base as the integer part, but using negative powers of the base ''b''. The most common variants are decimal (base 10) and binary (base 2). The latter is commonly known also as binary scaling. Thus, if ''n'' fraction digits are stored, the value will always be an integer multiple of ''b' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Programmable Calculators
Programmable calculators are calculators that can automatically carry out a sequence of operations under control of a stored program. Most are Turing complete, and, as such, are theoretically general-purpose computers. However, their user interfaces and programming environments are specifically tailored to make performing small-scale numerical computations convenient, rather than general-purpose use. The first programmable calculators such as the IBM CPC used punched cards or other media for program storage. Hand-held electronic calculators store programs on magnetic strips, removable read-only memory cartridges, flash memory, or in battery-backed read/write memory. Since the early 1990s, most of these flexible handheld units belong to the class of graphing calculators. Before the mass-manufacture of inexpensive dot-matrix LCDs, however, programmable calculators usually featured a one-line numeric or alphanumeric display. The Big Four manufacturers of programmable calculator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Vacuum-tube Computers
Vacuum-tube computers, now called first-generation computers, are programmable digital computers using vacuum-tube logic circuitry. They were preceded by systems using electromechanical relays and followed by systems built from discrete transistors. Some later computers on the list had both vacuum tubes and transistors. This list of vacuum-tube computers is sorted by date put into service: }) are identical, except input-output equipment.

List Of IBM Products
The following is a partial list of products, services, and subsidiaries of International Business Machines (IBM) Corporation and its predecessor corporations, beginning in the 1890s. This list is eclectic; it includes, for example, the ''AN/FSQ-7'', which was not a product in the sense of ''offered for sale'', but was a product in the sense of ''manufactured—produced by the labor of IBM''. Several machines manufactured for the Astronomical Computing Bureau at Columbia University are included, as are some machines built only as demonstrations of IBM technology. Missing are many RPQs, OEM products (semiconductors, for example), and supplies (punched cards, for example). These products and others are missing simply because no one has added them. IBM sometimes uses the same number for a system and for the principal component of that system. For example, the IBM 604 Calculating Unit is a component of the IBM 604 Calculating Punch. And different IBM divisions used the same model n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM 701
The IBM 701 Electronic Data Processing Machine, known as the Defense Calculator while in development, was IBM’s first commercial scientific computer and its first series production mainframe computer, which was announced to the public on May 21, 1952. It was invented and developed by Jerrier Haddad and Nathaniel Rochester based on the IAS machine at Princeton. The IBM 701 was the first computer in the IBM 700/7000 series, which were IBM’s high-end computers until the arrival of the IBM System/360 in 1964. The business-oriented sibling of the 701 was the IBM 702 and a lower-cost general-purpose sibling was the IBM 650, which gained fame as the first mass-produced computer in the world. History IBM 701 competed with Remington Rand's UNIVAC 1103 in the scientific computation market, which had been developed for the NSA, so it was held secret until permission to market it was obtained in 1951. In early 1954, a committee of the Joint Chiefs of Staff requested that the two ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tintin (character)
Tintin (; ) is the titular protagonist of ''The Adventures of Tintin'', the comic series by Belgian cartoonist Hergé. The character was created in 1929 and introduced in , a weekly youth supplement to the Belgian newspaper . Appearing as a young man with a round face and quiff hairstyle, Tintin is depicted as a precocious, multitalented reporter who travels the world with his dog Snowy. Since his inception in the early 20th century, Tintin has remained a popular literary figure with statues and commemorative murals of the character seen throughout Belgium. In addition to the original comic series, Tintin has appeared in numerous plays, radio shows, television shows, and feature films, including the 2011 film ''The Adventures of Tintin'', directed by Steven Spielberg. History Influences Hergé biographer Pierre Assouline noted that "Tintin had a prehistory", being influenced by a variety of sources that Hergé had encountered throughout his life. Hergé noted that during h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Adventures Of Tintin
''The Adventures of Tintin'' (french: Les Aventures de Tintin ) is a series of 24 bande dessinée#Formats, ''bande dessinée'' albums created by Belgians, Belgian cartoonist Georges Remi, who wrote under the pen name Hergé. The series was one of the most popular European comics of the 20th century. By 2007, a century after Hergé's birth in 1907, ''Tintin'' had been published in more than 70 languages with sales of more than 200 million copies, and had been adapted for radio, television, theatre and film. The series first appeared in French on 10 January 1929, in (''The Little Twentieth''), a youth supplement to the Belgian newspaper (''The Twentieth Century''). The success of the series led to serial (literature), serialised strips published in Belgium's leading newspaper (''The Evening'') and spun into a successful ''Tintin (magazine), Tintin'' magazine. In 1950, Hergé created Studios Hergé, which produced the canonical versions of 11 ''Tintin'' albums. The series is se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
