Compis
Compis (''COMPuter I Skolan'', also a pun on the colloquial Swedish word ''kompis'' meaning comrade or buddy) was a computer system intended for the general educational system in Sweden and sold to Swedish schools beginning in 1984 through the distributor Esselte Studium, who also was responsible for the software packages. The computers were also used in Danish, Finnish and Norwegian schools under the name Scandis. History In 1980, the ABC 80 used in the schools was regarded as becoming obsolete, and Styrelsen för teknisk utveckling (board for technical development) was tasked to find a replacement. In 1981, the procurement ''Tudis (Teknikupphandlingsprojekt Datorn i Skolan) '' was launched, and while the decision was controversial, Svenska Datorer AB was awarded the contract with development beginning in 1982. After Svenska Datorer went bankrupt, production was transferred to TeliDatorer/Telenova under Televerket (Sweden) The computer was distributed by Esselte and exclusiv ...

COMAL
COMAL (''Common Algorithmic Language'') is a computer programming language developed in Denmark by Børge R. Christensen and Benedict Løfstedt and originally released in 1975. COMAL was one of the few structured programming languages that was available for and comfortably usable on 8-bit home computers. It was based on the seminal BASIC programming language, adding multi-line statements and well-defined subroutines among other additions. "COMAL Kernel Syntax & Semantics" contains the formal definition of the language. Further extensions are common to many implementations. Design COMAL was created as a mixture of the prevalent educational programming languages of the time, BASIC, Pascal, and, at least in the Commodore and Compis versions, the turtle graphics of Logo. The language was meant to introduce structured programming elements in an environment where BASIC would normally be used. With the benefit of hindsight, COMAL looks like a Structured BASIC that has reasonab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel 80186
The Intel 80186, also known as the iAPX 186, or just 186, is a microprocessor and microcontroller introduced in 1982. It was based on the Intel 8086 and, like it, had a 16-bit external data bus multiplexed with a 20-bit address bus. The 80188 variant, with an 8-bit external data bus was also available. Description The 80186 series was generally intended for embedded systems, as microcontrollers with external memory. Therefore, to reduce the number of integrated circuits required, it included features such as clock generator, interrupt controller, timers, wait state generator, DMA channels, and external chip select lines. The initial clock rate of the 80186 was 6 MHz, but due to more hardware available for the microcode to use, especially for address calculation, many individual instructions completed in fewer clock cycles than on an 8086 at the same clock frequency. For instance, the common ''register+immediate'' addressing mode was significantly faster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ABC 80
The ABC 80 (Advanced BASIC Computer 80) was a personal computer engineered by the Swedish corporation Dataindustrier AB (DIAB) and manufactured by Luxor in Motala, Sweden in the late 1970s and early 1980s. It was introduced on the market in August 1978. The ABC 80 was based on an earlier modular computer system from the same company and built around a Z80 and of ROM containing a fast semi-compiling BASIC interpreter. It had of RAM as main memory and a dedicated (included) tape recorder for program and data storage, but could also be expanded to handle disk drives as well as many other peripherals. The ROM could be extended in increments of 1 or 4KB in order to handle such so called "options". The monitor was a black and white TV set modified for the purpose, an obvious choice since Luxor also made TVs. The ABC 80 was used in schools and officies around Scandinavia and parts of Europe. It was also used for industrial automation, scientific measurement and control systems. Lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unisys ICON
The ICON (also the CEMCorp ICON, Burroughs ICON, and Unisys ICON, and nicknamed the bionic beaver) was a networked personal computer built specifically for use in schools, to fill a standard created by the Ontario Ministry of Education. It was based on the Intel 80186 CPU and ran an early version of QNX, a Unix-like operating system. The system was packaged as an all-in-one machine similar to the Commodore PET, and included a trackball for mouse-like control. Over time a number of GUI-like systems appeared for the platform, based on the system's NAPLPS-based graphics system. The ICON was widely used, mostly in high schools in the mid to late 1980s, but disappeared after that time with the widespread introduction of PCs and Apple Macintoshes. History Development Origin In 1981, four years after the first microcomputers for mainstream consumers appeared, the Ontario Ministry of Education sensed that microcomputers could be an important component of education.

Education In Sweden
Education in Sweden is mandatory for children between ages 5/6 and 15/16 depending on when on the year they were born. The school year in Sweden runs from mid–late August to early/mid–June. The Christmas holiday from mid–December to early January divides the Swedish school year into two terms. Preschool is free for all families. The year children turn six they start the compulsory preschool class (), which acts as a transition phase between preschool and comprehensive schools. Children between ages 5/6 and 15/16 attend comprehensive school where a wide range of subjects are studied. All students study the same subjects, with exception for different language choices. The majority of schools are run municipally, but there are also privately owned schools, known as independent schools. Almost all students continue studying in three-year-long upper secondary schools where most students choose one out of 18 national programmes, some of which are vocational and some preparatory. ...

Megabyte
The megabyte is a multiple of the unit byte for digital information. Its recommended unit symbol is MB. The unit prefix ''mega'' is a multiplier of (106) in the International System of Units (SI). Therefore, one megabyte is one million bytes of information. This definition has been incorporated into the International System of Quantities. In the computer and information technology fields, other definitions have been used that arose for historical reasons of convenience. A common usage has been to designate one megabyte as (220 B), a quantity that conveniently expresses the binary architecture of digital computer memory. The standards bodies have deprecated this usage of the megabyte in favor of a new set of binary prefixes, in which this quantity is designated by the unit mebibyte (MiB). Definitions The unit megabyte is commonly used for 10002 (one million) bytes or 10242 bytes. The interpretation of using base 1024 originated as technical jargon for the byte multiples t ...

Hard Disk
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small rectangular box. Introduced by IBM in 1956, HDDs were the dominant secondary storage device for general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern era of servers and personal computers, though personal computing devices produced in large volume, like cell phones and tablets, rely ...

Local Area Network
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication circuits. Ethernet and Wi-Fi are the two most common technologies in use for local area networks. Historical network technologies include ARCNET, Token Ring and AppleTalk. History The increasing demand and usage of computers in universities and research labs in the late 1960s generated the need to provide high-speed interconnections between computer systems. A 1970 report from the Lawrence Radiation Laboratory detailing the growth of their "Octopus" network gave a good indication of the situation. A number of experimental and early commercial LAN technologies were developed in the 1970s. Cambridge Ring was developed at Cambridge University starting in 1974. Ethe ...

Productivity Software
Productivity software (also called personal productivity software or office productivity software) is application software used for producing information (such as documents, presentations, worksheets, databases, charts, graphs, digital paintings, electronic music and digital video). Its names arose from it increasing productivity, especially of individual office workers, from typists to knowledge workers, although its scope is now wider than that. Office suites, which brought word processing, spreadsheet, and relational database programs to the desktop in the 1980s, are the core example of productivity software. They revolutionized the office with the magnitude of the productivity increase they brought as compared with the pre-1980s office environments of typewriters, paper filing, and handwritten lists and ledgers. In the United States, some 78% of "middle-skill" occupations (those that call for more than a high school diploma but less than a bachelor's degree) now require the ...

Lotus Symphony For DOS
Lotus Symphony was an integrated software package for creating and editing text, spreadsheets, charts and other documents on the MS-DOS operating systems. It was released by Lotus Development as a follow-on to its popular spreadsheet program, Lotus 1-2-3, ''Computerworld'', July 16, 1984, pg. 66-67 and was produced from 1984–1992. Lotus Jazz on the Apple Macintosh was a sibling product. IBM revived the name Lotus Symphony in 2007 for a new office suite based on |
WordStar
WordStar is a word processor application for microcomputers. It was published by MicroPro International and originally written for the CP/M-80 operating system, and later written also for MS-DOS and other 16-bit PC OSes. Rob Barnaby was the sole author of the early versions of the program. Starting with WordStar 4.0, the program was built on new code written principally by Peter Mierau. WordStar dominated the market in the early and mid-1980s, succeeding the market leader Electric Pencil. WordStar was written with as few assumptions as possible about the operating system and machine hardware, allowing it to be easily ported across the many platforms that proliferated in the early 1980s. Because all of these versions had relatively similar commands and controls, users could move between platforms with equal ease. It was already popular when its inclusion with the Osborne 1 portable computer made the program the ''de facto'' standard for much of the small computer word-processing ...
