Single-board Computers
A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer. Single-board computers are commonly made as demonstration or development systems, for educational systems, or for use as embedded computer controllers. Many types of home computers or portable computers integrate all their functions onto a single printed circuit board. Unlike a desktop personal computer, single-board computers often do not rely on expansion slots for peripheral functions or expansion. Single-board computers have been built using a wide range of microprocessors. Simple designs, such as those built by computer hobbyists, often use static RAM and low-cost 32- or 64-bit processors like ARM. Other types, such as blade servers, would perform similar to a server computer, only in a more compact format. A computer-on-module is a type of single-board computer made to plug into ...

Blade Server
A blade server is a stripped-down server computer with a modular design optimized to minimize the use of physical space and energy. Blade servers have many components removed to save space, minimize power consumption and other considerations, while still having all the functional components to be considered a computer. Unlike a rack-mount server, a blade server fits inside a blade enclosure, which can hold multiple blade servers, providing services such as power, cooling, networking, various interconnects and management. Together, blades and the blade enclosure form a blade system, which may itself be rack-mounted. Different blade providers have differing principles regarding what to include in the blade itself, and in the blade system as a whole. In a ''standard'' server-rack configuration, one rack unit or 1U— wide and tall—defines the minimum possible size of any equipment. The principal benefit and justification of blade computing relates to lifting this restri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KIM-1
The KIM-1, short for ''Keyboard Input Monitor'', is a small MOS Technology 6502, 6502-based single-board computer developed and produced by MOS Technology, MOS Technology, Inc. and launched in 1976. It was very successful in that period, due to its low price (thanks to the inexpensive 6502 microprocessor) and easy-access expandability. History MOS Technology's first processor, the MOS Technology 6501, 6501, could be plugged into existing motherboards that used the Motorola 6800, allowing potential users (i.e. engineers and hobbyists) to get a development system up and running very easily using existing hardware. Motorola immediately sued, forcing MOS to pull the 6501 from the market. Changing the pin layout produced the "lawsuit-friendly" MOS Technology 6502, 6502. Otherwise identical to the 6501, it nevertheless had the disadvantage of having no machine in which new users could quickly start using the central processing unit, CPU. Chuck Peddle, leader of the 650x group at M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BBC Micro
The BBC Microcomputer System, or BBC Micro, is a family of microcomputers developed and manufactured by Acorn Computers in the early 1980s as part of the BBC's Computer Literacy Project. Launched in December 1981, it was showcased across several educational BBC television programmes, such as ''The Computer Programme'' (1982), ''Making the Most of the Micro'' and ''Computers in Control'' (both 1983), and ''Micro Live'' (1985). Created in response to the BBC's call for bids for a microcomputer to complement its broadcasts and printed material, Acorn secured the contract with its rapidly prototyped “Proton” system, which was subsequently renamed the BBC Micro. Although it was announced towards the end of 1981, production issues initially delayed the fulfilment of many orders, causing deliveries to spill over into 1982. Nicknamed the “Beeb”, it soon became a fixture in British schools, advancing the BBC’s goal of improving computer literacy. Renowned for its strong build q ...

Acorn Electron
The Acorn Electron (nicknamed the Elk inside Acorn and beyond) was introduced as a lower-cost alternative to the BBC Micro educational/home computer, also developed by Acorn Computers, to provide many of the features of that more expensive machine at a price more competitive with that of the ZX Spectrum. It has 32 kilobytes of random-access memory, RAM, and its read-only memory, ROM includes BBC BASIC II together with the Acorn MOS, operating system. Announced in 1982 for a possible release the same year, it was eventually introduced on 25 August 1983 priced at £199. The Electron is able to save and load programs onto compact audio cassette, audio cassette via a cable, originally supplied with the computer, connecting it to any standard tape recorder with the appropriate sockets. It is capable of bitmapped graphics, and can use either a contemporary television set, a colour (RGB) monitor or a monochrome monitor as its display. Several expansions were made available to provide m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microcomputer
A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor. The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with a keyboard and screen for input and output) are also personal computers (in the generic sense). An early use of the term "personal computer" in 1962 predates microprocessor-based designs. ''(See "Personal Computer: Computers at Companies" reference below)''. A "microcomputer" used as an embedded control system may have no human-readable input and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microcontroller
A microcontroller (MC, uC, or μC) or microcontroller unit (MCU) is a small computer on a single integrated circuit. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. Program memory in the form of NOR flash, OTP ROM, or ferroelectric RAM is also often included on the chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general-purpose applications consisting of various discrete chips. In modern terminology, a microcontroller is similar to, but less sophisticated than, a system on a chip (SoC). A SoC may include a microcontroller as one of its components but usually integrates it with advanced peripherals like a graphics processing unit (GPU), a Wi-Fi module, or one or more coprocessors. Microcontrollers are used in automatically controlled products and devices, such as automobile engi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radio-Electronics
''Radio-Electronics'' was an American electronics magazine that was published under various titles from 1929 to 2003. Hugo Gernsback, sometimes called the father of science fiction, started it as ''Radio-Craft'' in July 1929. The title was changed to ''Radio-Electronics'' in October 1948 and again to ''Electronics Now'' in July 1992. In January 2000 it was merged with Gernsback's ''Popular Electronics'' to become ''Poptronics''. Gernsback Publications ceased operations in December 2002 and the January 2003 issue was the last. Over the years, ''Radio-Electronics'' featured audio, radio, television and computer technology. The most notable articles were the TV Typewriter (September 1973) and the Mark-8 computer (July 1974). These two issues are considered milestones in the Microcomputer revolution, home computer revolution.

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 ...

Intel 8080
The Intel 8080 is Intel's second 8-bit computing, 8-bit microprocessor. Introduced in April 1974, the 8080 was an enhanced successor to the earlier Intel 8008 microprocessor, although without binary compatibility.'' Electronic News'' was a weekly trade newspaper. The same advertisement appeared in the :File:Intel 8080 Advertisement May 1974.jpg, May 2, 1974, issue of ''Electronics'' magazine. Originally intended for use in Embedded system, embedded systems such as calculators, cash registers, computer terminals, and industrial robots, its robust performance soon led to adoption in a broader range of systems, ultimately helping to launch the microcomputer industry. Several key design choices contributed to the 8080’s success. Its 40‑pin package simplified interfacing compared to the 8008’s 18‑pin design, enabling a more efficient data bus. The transition to NMOS logic, NMOS technology provided faster transistor speeds than the 8008's PMOS logic, PMOS while also simplifyin ...
