Galaksija (computer)
The Galaksija ( sr-Cyrl, Галаксија; , meaning "Galaxy") was a build-it-yourself computer designed by Voja Antonić. It was featured in the special edition ''Računari u vašoj kući'' (''Computers in your home'', written by Dejan Ristanović) of a popular eponymous science magazine, published late December 1983 in Belgrade, SFRY, Yugoslavia. Kits were available but not required as it could be built entirely out of standard off-the-shelf parts. It was later also available in complete form. History In the early eighties, restrictions in Socialist Federal Republic of Yugoslavia, SFR Yugoslavia prevented importing computers into the country. At the same time, even the cheapest computers available in the West were nearing average monthly salaries. This meant that only a relative minority of people owned one — mostly a ZX Spectrum or a Commodore 64, though most Yugoslavs were only familiar with a programmable calculator. According to his own words, some time in 1983, Voja A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Home Computer
Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single, non-technical user. These computers were a distinct market segment that typically cost much less than business, scientific, or engineering-oriented computers of the time, such as those running CP/M or the IBM PC, and were generally less powerful in terms of computer memory, memory and expandability. However, a home computer often had better video display controller, graphics and sound than contemporary business computers. Their most common uses were word processing, playing video games, and computer programming, programming. Home computers were usually sold already manufactured in stylish metal or plastic enclosures. However, some home computers also came as commercial electronic kits, like the ZX80, Sinclair ZX80, which were both h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RCA 1802
The COSMAC (Complementary Symmetry Monolithic Array Computer) is an 8-bit microprocessor family introduced by RCA. It is historically notable as the first CMOS microprocessor. The first production model was the two-chip CDP1801R and CDP1801U, which were later combined into the single-chip CDP1802. The 1802 represented the majority of COSMAC production, and today the entire line is known simply as the RCA 1802. The processor design traces its history to an experimental home computer designed by Joseph Weisbecker in the early 1970s, built at his home using TTL components. RCA began development of the CMOS version of the processor design in 1973, sampling it in 1974 with plans to move to a single-chip implementation immediately. Jerry Herzog led the design of the single-chip version, which sampled in 1975 and entered production in 1976. In contrast to most designs of the era, which were fabricated using the NMOS process, the COSMAC was implemented in CMOS form and used static l ...

Elektronika Inženjering
Elektronika, also spelt Electronika and Electronica (, "Electronics"), is the brand name used for many different electronic products built by factories belonging to the Soviet Ministry of Electronic Industry, including calculators, electronic watches, portable games, and radios. Many Elektronika designs were the result of efforts by Soviet engineers, who were working for the Soviet military–industrial complex but were challenged with producing consumer goods that were in great shortage in the Soviet Union. The brand is still in use in Belarus. Calculators Most notable is a line of calculators, which started production in 1968. The Elektronika calculators were produced in a variety of sizes and function sets, ranging from large, bulky four-function calculators to smaller models designed for use in schools operating on a special, safer 42V standard (like the MK-SCH-2). As time progressed, Elektronika calculators were produced that supported more advanced calculations, with s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galaksija (magazine)
''Galaksija'' was a monthly magazine for popularization of science and science fiction that was published in Yugoslavia from 1972 to the 1990s by BIGZ. Its headquarters was in Belgrade. The '' Računari'' computer magazine was initially a special edition of ''Galaksija'' in December 1983. Another project launched by the magazine was the Galaksija home computer constructed by Voja Antonić. Its do-it-yourself "Do it yourself" ("DIY") is the method of building, modifying, or repairing things by oneself without the direct aid of professionals or certified experts. Academic research has described DIY as behaviors where "individuals use raw and semi- ... schematics were first published by ''Galaksija''. Editors *1972-1987 Gavrilo Vučković *1987-1989 Stanko M.

EPROM
An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of programmable read-only memory (PROM) integrated circuit, chip that retains its data when its power supply is switched off. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile. It is an array of floating-gate transistors individually programmed by an electronic device that supplies higher voltages than those normally used in digital circuits. Once programmed, an EPROM can be erased by exposing it to strong ultraviolet (UV) light source (such as from a mercury-vapor lamp). EPROMs are easily recognizable by the transparent fused quartz (or on later models' resin) window on the top of the package, through which the silicon chip is visible, and which permits exposure to ultraviolet light during erasing. It was invented by Dov Frohman in 1971. Operation Development of the EPROM memory cell (computing), memory cell started with investi ...

Integrated Circuit
An integrated circuit (IC), also known as a microchip or simply chip, is a set of electronic circuits, consisting of various electronic components (such as transistors, resistors, and capacitors) and their interconnections. These components are etched onto a small, flat piece ("chip") of semiconductor material, usually silicon. Integrated circuits are used in a wide range of electronic devices, including computers, smartphones, and televisions, to perform various functions such as processing and storing information. They have greatly impacted the field of electronics by enabling device miniaturization and enhanced functionality. Integrated circuits are orders of magnitude smaller, faster, and less expensive than those constructed of discrete components, allowing a large transistor count. The IC's mass production capability, reliability, and building-block approach to integrated circuit design have ensured the rapid adoption of standardized ICs in place of designs using discre ...

Computer Keyboard
A computer keyboard is a built-in or peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or Push-button, keys to act as Mechanical keyboard, mechanical levers or Electronic switching system, electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter-style keyboards have been the main input device, input method for computers since the 1970s, supplemented by the computer mouse since the 1980s, and the touchscreen since the 2000s. Keyboard keys (buttons) typically have a set of characters Engraving, engraved or Printing, printed on them, and each press of a key typically corresponds to a single written symbol. However, producing some symbols may require pressing and holding several keys simultaneously or in sequence. While most keys produce character (computing), characters (Letter (alphabet), letters, Numerical digit, numbers or symbols), other keys (such as the escape key) can prompt the ...

Buje
Buje (; ) is a town situated in Istria, Croatia's westernmost peninsula. Buje was known as the "sentinel of Istria" for its hilltop site located inland from the Adriatic Sea. History Buje has a rich history; traces of life in the region date back to prehistoric times. The town developed from a Roman and Venetian settlement into a medieval town. Buje was part of the Republic of Venice from 1358 until 1797, when the Treaty of Campo Formio handed it over to Austria. It was annexed by France after the Treaty of Schönbrunn in 1809 but restored to Austria at the Congress of Vienna in 1815. Buje passed to Italy at the end of World War I in 1918, where it remained until 1945. In 1947, it became part of the Free Territory of Trieste Zone B, which was administered by Yugoslavia. In October 1954, Zone B together with Buje was united with the Socialist Republic of Croatia, and remains part of independent Croatia today.

Printed Circuit Board
A printed circuit board (PCB), also called printed wiring board (PWB), is a Lamination, laminated sandwich structure of electrical conduction, conductive and Insulator (electricity), insulating layers, each with a pattern of traces, planes and other features (similar to wires on a flat surface) Chemical milling, etched from one or more sheet layers of copper laminated onto or between sheet layers of a non-conductive substrate. PCBs are used to connect or Electrical wiring, "wire" Electronic component, components to one another in an electronic circuit. Electrical components may be fixed to conductive pads on the outer layers, generally by soldering, which both electrically connects and mechanically fastens the components to the board. Another manufacturing process adds Via (electronics), vias, metal-lined drilled holes that enable electrical interconnections between conductive layers, to boards with more than a single side. Printed circuit boards are used in nearly all e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
