LogAbax
LogAbax was a French computer brand. Founded in 1942, the company was one of France's pioneers in computer manufacturing. The name is composed of two abbreviations: ''Log'' from logarithm and ''Abax'' from abacus. History The company was created in 1942 as ''“La Société Française des Brevets LogAbax''”. In 1947 it employs twenty people and has a factory located at Malakoff. The company obtains a contract from CNRS for the construction of a " Couffignal machine", intended to be the fist French " electronic calculation machine". Between 1948 and 1950 LogAbax studies an electronic meter, related to the electronic calculator development. In 1968 ''LogAbax'' and ''Bariquand et Marre'' merge, forming ''LogAbax SA''. The LX 500, a personal computer based on the Z80 microprocessor and running the CP/M operating system, is presented in 1978. Due to poor results in the late 1970s, LogAbax files for bankruptcy in 1981, with Olivetti becoming the majority shareholder, creatin ...

Persona 1600
The Olivetti M24 is a computer that was sold by Olivetti in 1983 using the Intel 8086 CPU. The system was sold in the United States under its original name by Docutel/Olivetti of Dallas. AT&T and Xerox bought rights to rebadge the system as the AT&T PC 6300 and the Xerox 6060 series, respectively. (AT&T owned 25% of Olivetti around this time.) The AT&T 6300, launched in June 1984, was AT&T's first attempt to compete in the PC compatible market. It was also available in France as the PERSONA 1600, built by LogAbax. Versions The initial 1984 US version named AT&T 6300 came with either one or two 360 KB 5.25" floppy drives; a hard disk was not offered. In Europe, Olivetti launched a 10 MHz version: the Olivetti M24 SP, announced in November 1985, a contender for the title of "highest clocked 8086 computer" as its processor was the fastest grade of 8086-2, rated for a maximum speed of exactly the same 10 MHz.

Olivetti M19
The Olivetti M19 was a personal computer made in 1986 by the Italian company Olivetti. It has an 8088 at 4.77 or 8 MHz and 256–640 KB of RAM. The BIOS is Revision Diagnostics 3.71. In the UK, it was sold by Acorn Computers as the Acorn M19, with additional software also available via Acorn. In France, it was available as the Persona 1300, sold by LogAbax. The machine came with three operating systems: MS-DOS 2.11 / 3.1, Concurrent DOS and UCSD p-System. It is capable of displaying graphics in standard CGA or Plantronics Colorplus mode (320x200 pixel with 16 colors and 640x200 with 4 colors). The M19 was sold with two floppy disk drives (360 KB format). A hard drive option was made available later, in the form of a 5 MB (later 10 MB) hard drive in an add-on case (aka "sidecar") attached to the left hand side of the computer by four machine screws.

Olivetti M28
The Olivetti M28 personal computer, introduced in 1986, was the successor to the Olivetti M24. It had an Intel 80286 CPU running at 8 MHz and 512 KB (expandable to 1024 KB on the motherboard) of RAM, featuring a 5.25" floppy drive and a 20 MB hard drive. The operating systems were MS-DOS 3.2 and XENIX. The computer had room to install three disk units, as opposed to only two on the M24. It was possible to install a 70 MB hard drive, a 80287 math co-processor and a enhanced CGA compatible graphic card capable of displaying 640x400 pixels with 16 colors. The Olivetti M28 was rebranded as the AT&T PC 6310 by AT&T in 1987 and sold on the US market. It was available in France as the Persona 1800, sold by LogAbax.

Computing For All
The Computing for All plan (''Plan Informatique pour Tous - IPT'') was a French government plan to introduce computers to the country's 11 million pupils. A second goal was to support national industry. It followed several introductory computer science programs in schools since 1971. The IPT plan was presented to the press on January 25, 1985 by Laurent Fabius, Prime Minister at the time. It aimed to set up, from the start of that school year, more than 120,000 machines in 50,000 schools and to train 110,000 teachers. Its estimated cost was 1.8 billion francs, including 1.5 billion for equipment. The plan was abandoned in 1989. Description The selection of industry partners was entrusted to Gilbert Trigano, co-founder of Club Méditerranée, connected with French companies such as Exelvision, Léanord, SMT Goupil, Thomson, Bull, LogAbax, etc. This choice was political because its initiator, Jean-Jacques Servan-Schreiber, had indicated his preference for Macintosh, which would be s ...

Electronic Calculator
An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. The first solid-state electronic calculator was created in the early 1960s. Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel for the Japanese calculator company Busicom. Modern electronic calculators vary from cheap, give-away, credit-card-sized models to sturdy desktop models with built-in printers. They became popular in the mid-1970s as the incorporation of integrated circuits reduced their size and cost. By the end of that decade, prices had dropped to the point where a basic calculator was affordable to most and they became common in schools. Computer operating systems as far back as early Unix have included interactive calculator programs such as dc and hoc, and interactive BASIC could be used to do calculations on most 1970s an ...

Abacus
The abacus (''plural'' abaci or abacuses), also called a counting frame, is a calculating tool which has been used since ancient times. It was used in the ancient Near East, Europe, China, and Russia, centuries before the adoption of the Hindu-Arabic numeral system. The exact origin of the abacus has not yet emerged. It consists of rows of movable beads, or similar objects, strung on a wire. They represent digits. One of the two numbers is set up, and the beads are manipulated to perform an operation such as addition, or even a square or cubic root. In their earliest designs, the rows of beads could be loose on a flat surface or sliding in grooves. Later the beads were made to slide on rods and built into a frame, allowing faster manipulation. Abacuses are still made, often as a bamboo frame with beads sliding on wires. In the ancient world, particularly before the introduction of positional notation, abacuses were a practical calculating tool. The abacus is still used to te ...

History Of Computing In France
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...
