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 i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

List Of Early Microcomputers
This is a list of early microcomputers sold to hobbyists and developers. These microcomputers were often sold as "DIY" kits or pre-built machines in relatively small numbers in the mid-1970s. These systems were primarily used for teaching the use of microprocessors and supporting peripheral devices, and unlike home computers were rarely used with pre-written application software. Most early micros came without alphanumeric keyboards or displays, which had to be provided by the user. RAM was quite small in the unexpanded systems (a few hundred bytes to a few kilobytes). By 1976 the number of pre-assembled machines was growing, and the 1977 introduction of the "Trinity" of Commodore PET, TRS-80 and Apple II generally marks the end of the "early" microcomputer era, and the advent of the consumer home computer era that followed. Discrete logic Before the advent of microprocessors, it was possible to build small computers using small-scale integrated circuits (ICs), where each IC co ...

List Of Home Computers
The home computers between 1977 and about 1995 were different from today's uniform and predictable machines. During this time it made economic sense for manufacturers to make microcomputers aimed at the home user. By simplifying the machines, and making use of household items such as television sets and cassette recorders instead of dedicated computer peripherals, the home computer allowed the consumer to own a computer at a fraction of the price of computers oriented to small business. Today, the price of microcomputers has dropped to the point where there's no advantage to building a separate, incompatible series just for home users. While many office-type personal computers were used in homes, in this list a "home computer" is a factory-assembled mass-marketed consumer product, usually at significantly lower cost than contemporary business computers. It would have an alphabetic keyboard and a multi-line alphanumeric display, the ability to run both games software as well as a ...

List Of Home Computers By Video Hardware
This is a list of home computers, sorted alphanumerically, which lists all relevant details of their video hardware. Home computers are the second generation of desktop computers, entering the market in 1977 and becoming common during the 1980s. A decade later they were generally replaced by IBM PC compatible "PCs", although technically home computers are also classified as personal computers. Examples of typical early home computers are the TRS-80, Atari 400/800, BBC Micro, the ZX Spectrum, the MSX 1, the Amstrad CPC 464 and the Commodore 64. Examples of typical late home computers are MSX 2 systems, and the Amiga and Atari ST systems. Note: in cases of manufacturers who have made both home and personal computers, only machines fitting into the ''home'' computer category are listed. Systems in the personal computer category, except for Early Macintosh PCs, are generally based on the VGA standard and use a video chip known as a Graphics Processing Unit. Very early PCs used ...
