KC87
The Robotron KC 87, fully known as the Kleincomputer robotron KC 87 (''KC'' standing for ''Kleincomputer'', lit. "small computer"), was an 8-bit home computer released in 1986 and produced in East Germany by the Volkseigener Betrieb, VEB VEB Robotron, Robotron-Meßelektronik "Otto Schön" Dresden, part of the Combine (enterprise), Kombinat VEB Robotron, Robotron. The first model in the series, the Robotron Z 9001, was introduced in 1984 and renamed Robotron KC 85/1 in 1985. Despite similar names, the Robotron home computers were not directly related to the KC 85 series produced by the Kombinat Mikroelektronik Erfurt, VEB Mikroelektronik "Wilhelm Pieck" Mühlhausen. The availability of the Robotron KC series for private customers was very limited. The computers were mostly used at educational institutions, organizations, and enterprises. Therefore, the Extracurricular activity, extracurricular use of home computers was often allowed for students at institutions and organizations. ...

Robotron Z1013
The MRB Z1013 (german: Mikrorechnerbausatz, links=no, lit=microcomputer kit) was an East German single-board computer produced by VEB Robotron Riesa which was primarily intended for private use and educational institutions. It was powered by a U880 processor (a Z80 clone) and sold together with a membrane (flat foil) keyboard. Initially, the kit was equipped with 16-KByte DRAM, which was later replaced by a 64-KByte version. The kits first became available for sale in 1985 and were distributed in a unique way at the time. To purchase it, buyers had to send a postcard to the Robotron shop in Erfurt and wait six to twelve months and then to pick the kits up in person. The package contained the assembled and tested motherboard, a membrane keyboard, various small parts and detailed technical documentation. This basic kit was shipped without a power supply or casing for the PCB. Most users tended to program the kit using the BASIC interpreter, which was loadable from compact casse ...

KC 85
The KC 85 ('KC' meaning "Kleincomputer", or "small computer") were models of microcomputers built in East Germany, first in 1984 by VEB Robotron (the KC 85/1) and later by VEB Mikroelektronik " Wilhelm Pieck" Mühlhausen (KC 85/2, KC 85/3 and KC 85/4). Due to demand by institutions and enterprises exceeding supply, KC 85 systems were virtually unavailable for sale to private customers. Technical information They were based on the U880 CPU (an East German clone of the Z80), with clock speeds of 1.75 and 2 MHz. There was a single 8867 kHz crystal oscillating at twice the PAL chrominance frequency and a divide-by-10, multiply-by-16 phase locked loop was used to derive a 14.2 MHz clock from which the pixel clock (7.1 MHz) and processor clock (1.77 MHz) was derived by division by 2 and 8, respectively (KC85/2, KC85/3 and KC85/4 used the same circuit for this purpose, since the digital to analog video conversion PCB where the clock generation was situ ...

Video Game
Video games, also known as computer games, are electronic games that involves interaction with a user interface or input device such as a joystick, game controller, controller, computer keyboard, keyboard, or motion sensing device to generate visual feedback. This feedback mostly commonly is shown on a video display device, such as a TV set, computer monitor, monitor, touchscreen, or virtual reality headset. Some computer games do not always depend on a graphics display, for example List of text-based computer games, text adventure games and computer chess can be played through teletype printers. Video games are often augmented with audio feedback delivered through loudspeaker, speakers or headphones, and sometimes with other types of feedback, including haptic technology. Video games are defined based on their computing platform, platform, which include arcade video games, console games, and PC game, personal computer (PC) games. More recently, the industry has expanded on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Programming Language
A programming language is a system of notation for writing computer programs. Most programming languages are text-based formal languages, but they may also be graphical. They are a kind of computer language. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning), which are usually defined by a formal language. Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard) while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common. Programming language theory is the subfield of computer science that studies the design, implementation, analysis, characterization, and classification of programming languages. Definitions There are many considerations when defining ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Printer (computing)
In computing, a printer is a peripheral machine which makes a persistent representation of graphics or text, usually on paper. While most output is human-readable, bar code printers are an example of an expanded use for printers. Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers. History The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000. The first patented printing mechanism for applying a marking medium to a recording medium or more particularly an electrostatic inking apparatus and a method for electrostatically depositing ink on controlled areas of a receiving medium, was in 1962 by C. R. Winston, Teletype Corporation, using continuous inkjet printing. The ink was a red stamp-pad ink manufactured by Phillips Process Company of Rochester, NY under the name Clear ...

Random-access Memory
Random-access memory (RAM; ) is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks, CD-RWs, DVD-RWs and the older magnetic tapes and drum memory), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement. RAM contains multiplexing and demultiplexing circuitry, to connect the data lines to the addressed storage for reading or writing the entry. Usually more than one bit of storage is accessed by the same address, and RAM devices often have multiple data lines and are said to be "8-bit" or "16-bit", etc ...

Cassette Deck
A cassette deck is a type of tape machine for playing and recording audio cassettes that does not have a built-in power amplifier or speakers, and serves primarily as a transport. It can be a part of an automotive entertainment system, a part of a portable mini system or a part of a home component system. In the latter case it is also called a component cassette deck or just a component deck. A "tape recorder" is a more generic term to identify a device that usually has a self-contained power amplifier and either has a built-in speaker or comes packaged with one. History Origins The first consumer tape recorder to employ a tape reel permanently housed in a small removable cartridge was the RCA tape cartridge, which appeared in 1958 as a predecessor to the cassette format. At that time, reel to reel recorders and players were commonly used by enthusiasts, but required large individual reels and tapes which had to be threaded by hand, making them less-accessible to the casu ...

Cassette Tape
The Compact Cassette or Musicassette (MC), also commonly called the tape cassette, cassette tape, audio cassette, or simply tape or cassette, is an analog audio, analog magnetic tape recording format for Sound recording and reproduction, audio recording and playback. Invented by Lou Ottens and his team at the Netherlands, Dutch company Philips in 1963, Compact Cassettes come in two forms, either already containing content as a prerecorded cassette (''Musicassette''), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user. Although List of magnetic tape cartridges and cassettes, other tape cassette formats have also existed - for example the Microcassette - the generic term ''cassette tape'' is normally always used to refer to the Compact Cassette because of its ubiquity. Its uses have ranged from Personal stereo, portable audio to home recording to data storage for early microcomputers; the Compact Cassette technology was originally ...

Extracurricular Activity
An extracurricular activity (ECA) or extra academic activity (EAA) or cultural activities is an activity, performed by students, that falls outside the realm of the normal curriculum of school, college or university education. Such activities are generally voluntary (as opposed to mandatory), social, philanthropic, and often involve others of the same age. Students and staff direct these activities under faculty sponsorship, although student-led initiatives, such as independent newspapers, are very common. However, sometimes the school principals and teachers also bring in these activities in the school among the students. Benefits of participation A group study conducted by surveying school-age students in the National Longitudinal Study of Adolescent Health revealed that 70% of adolescents in the USA are involved in some form of extracurricular activities. Other studies have shown being involved in extracurricular activities reduces the likelihood of dropping out of school ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
