Floppy Disk Variants
The floppy disk is a data storage and transfer medium that was ubiquitous from the mid-1970s well into the 2000s. Besides the 3½-inch and 5¼-inch formats used in IBM PC compatible systems, or the 8-inch format that preceded them, many proprietary floppy disk formats were developed, either using a different disk design or special layout and encoding methods for the data held on the disk. Non-standard media and devices IBM DemiDiskette In the early 1980s, IBM Rochester developed a 4-inch floppy disk drive, the Model 341 and an associated diskette, the DemiDiskette. At about half the size of the original 8-inch floppy disk the name derived from the prefix ''demi'' for "half". This program was driven by aggressive cost goals, but missed the pulse of the industry. The prospective users, both inside and outside IBM, preferred standardization to what by release time were small cost reductions, and were unwilling to retool packaging, interface chips and applications for a prop ...

Amstrad PCW
The Amstrad PCW series is a range of personal computers produced by United Kingdom, British company Amstrad from 1985 to 1998, and also sold under licence in Europe as the "Joyce" by the German electronics company Schneider Computer Division, Schneider in the early years of the series' life. The PCW, short for ''Personal Computer Word-processor'', was targeted at the word processing and Small office/home office, home office markets. When it was launched the cost of a PCW system was under 25% of the cost of almost all IBM-compatible PC systems in the UK, and as a result the machine was very popular both in the UK and in Europe, persuading many technophobes to venture into using computers. The series sold 8 million units. The last two models, introduced in the mid-1990s, were commercial failures, being squeezed out of the market by the falling prices, greater capabilities, and wider range of software for IBM PC compatibles. The series consists of PCW 8256 and PCW 8512 (introduced in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amstrad CPC
The Amstrad CPC (short for "Colour Personal Computer") is a series of 8-bit home computers produced by Amstrad between 1984 and 1990. It was designed to compete in the mid-1980s home computer market dominated by the Commodore 64 and the ZX Spectrum; it successfully established itself primarily in the United Kingdom, France, Spain, and the German-speaking parts of Europe, and also Canada. The series spawned a total of six distinct models: The ''Amstrad CPC 464, CPC 464'', ''CPC 664'', and ''CPC 6128'' were highly successful competitors in the European home computer market. The later ''464 plus'' and ''6128 plus'', intended to prolong the system's lifecycle with hardware updates, were considerably less successful, as was the attempt to repackage the ''plus'' hardware into a game console as the ''GX4000''. The CPC models' hardware is based on the Zilog Z80A CPU, complemented with either 64 or 128 KB of Random-access memory, RAM. Their computer-in-a-keyboard design prominently ...

AMSoft Compact Floppy Disc 20071208
Amsoft was a wholly owned subsidiary of Amstrad, PLC, founded in 1984 and re-integrated with its parent company in 1989. Its purpose was to provide an initial infrastructure of software and services for users of Amstrad's range of home computers, the Amstrad CPC and, from 1986, the ZX Spectrum. Many people's first contact with software on an Amstrad home computer would have been an Amsoft title, as several titles were included in the sales bundles. History While developing its first home computer, the Amstrad CPC 464, Amstrad assessed that part of the success of its competitors' machines was the backing of a grown infrastructure of software and services. Being a newcomer to the computer market, Amstrad decided to artificially create this infrastructure for the launch of their own computers. In February 1984, Amstrad founded its ''Amsoft'' division headed by Roland Perry and William Poel who at the time were also overseeing the development of the Amstrad CPC 464 itself. Most prom ...

Floppy-disk Controller
A floppy-disk controller (FDC) is a hardware component that directs and controls reading from and writing to a computer's floppy disk drive (FDD). It has evolved from a discrete set of components on one or more circuit boards to a special-purpose integrated circuit (IC or "chip") or a component thereof. An FDC is responsible for reading data presented from the host computer and converting it to the drive's on-disk format using one of a number of encoding schemes, like FM encoding (single density) or MFM encoding (double density), and reading those formats and returning it to its original binary values. Depending on the platform, data transfers between the controller and host computer would be controlled by the computer's own microprocessor, or an inexpensive dedicated microprocessor like the MOS 6507 or Zilog Z80. Early controllers required additional circuitry to perform specific tasks like providing clock signals and setting various options. Later designs included more of t ...
