The CPC 464 is the first personal home computer built by Amstrad. Released in 1984, it was the first entry in the Amstrad CPC family of home computers. The CPC 464 was one of the bestselling and best produced microcomputers, with more than 2 million units sold in Europe. [2] The British home computer boom had already peaked before Amstrad announced the CPC 464 (which stood for Colour Personal Computer) which they then released a mere nine months later. [3]
Amstrad was known for cheap hi-fi products but had not broken into the home computer market until the CPC 464. [1] Their consumer electronic sales were starting to plateau and owner and founder Alan Sugar stated "We needed to move on and find another sector or product to bring us back to profit growth". [4] Work started on the Amstrad home computer in 1983 with engineer Ivor Spital who concluded that Amstrad should enter the home computer market, offering a product that integrated low-cost hardware to be sold at an affordable "impulse-purchase price". [3]
Spital wanted to offer a device that would not commandeer the family TV but instead be an all-in-one computer with its own monitor, thus freeing up the TV and allowing others to play video games at the same time. [3]
Bill Poel, General Manager of Amsoft (Amstrad's software division), said during the launch press release that if the computers were not on the shelves by the end of June, "I will be prepared to sit down and eat one in Trafalgar Square." [5]
The CPC 464 is powered by the Zilog Z80 processor [6] after the original attempts to use the 6502 processor, being used in the Apple II amongst many other 8-bit computer families, failed. [3] The Z80 runs at 4 MHz, has 64 KB of memory and runs AMSDOS, Amstrad's own OS. The unit includes a built-in tape drive and the choice of a colour or green monochrome monitor. [6]
The graphics, which uses a Motorola 6845 chip for timing and address generation, provides 3 standard display modes, each using colours chosen from a palette of 27. [1] [7]
Its sound is supplied using the General Instrument AY-3-8912 sound chip that provides 3-voice, 8-octave sound capacity through a built-in loudspeaker with volume control. Later versions of the 464 have a headphone jack that can also be used for external speakers. [1]
The CPC 464's code name during development was 'Arnold'. [2] [6]
The 464 was popular with consumers for various reasons. Aside from the joystick port, the computer, keyboard, and tape deck were all combined into one unit [2] that attached to the monitor via two cables. [8] The monitor also contained the power supply unit which powered the whole unit via one wall plug. [1] It did not have very many wires and was simple enough for even the most inexperienced user to install. [8]
The Amstrad CPC 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, where it successfully established itself primarily in the United Kingdom, France, Spain, and the German-speaking parts of Europe.
The Apple II is a personal computer released by Apple Inc. in June 1977. It was one of the first successful mass-produced microcomputer products and is widely regarded as one of the most important personal computers of all time due to its role in popularizing home computing and influencing later software development.
The ZX Spectrum is an 8-bit home computer developed and marketed by Sinclair Research. Considered one of the most influential computers ever made, it is also one of the best-selling British computers ever, with over five million units sold. It was released in the United Kingdom on 23 April 1982, and around the world in the following years, most notably in Europe, the United States, and Eastern Bloc countries.
Amstrad was a British consumer electronics company, founded in 1968 by Alan Sugar. During the 1980s, the company was known for its home computers beginning with the Amstrad CPC and later also the ZX Spectrum range after the Sinclair deal, which led it to have a substantial share of the PC market in Britain. In the following decade it shifted focus towards communication technologies, and its main business during the 2000s was the manufacture of satellite television set-top boxes for Sky, which Amstrad had started in 1989 as the then sole supplier of the emerging Sky TV service.
The Amstrad PCW series is a range of personal computers produced by British company Amstrad from 1985 to 1998, and also sold under licence in Europe as the "Joyce" by the German electronics company Schneider in the early years of the series' life. The PCW, short for Personal Computer Word-processor, was targeted at the word processing and 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 is reported to have sold 8 million units. However 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-compatible PCs.
Locomotive Basic is a proprietary dialect of the BASIC programming language written by Locomotive Software on the Amstrad CPC and the later Locomotive BASIC-2 as a GEM application on the Amstrad PC1512 and 1640. It was the main descendant of Mallard BASIC, the interpreter for CP/M supplied with the Amstrad PCW.
The Amstrad PC1512 was Amstrad's mostly IBM PC-compatible computer system, launched in 1986, and advertised with prices from £399 plus VAT. The system was also marketed in the US by Texas-based Vidco Inc. from the start of 1987. Later in 1987, a slightly updated version called the PC1640 was introduced, also marketed as the PC6400 and Sinclair PC500. Schneider branded machines for the German market were also sold.
The Enterprise is a Zilog Z80-based home computer announced in 1983, but due to a series of delays, was not commercially available until 1985. It was developed by British company Intelligent Software and marketed by Enterprise Computers.
MicroBee was a series of networkable home computers by Applied Technology, which became publicly listed company MicroBee Systems Limited soon after its release. The original Microbee computer was designed in Australia by a team including Owen Hill and Matthew Starr.
The GX4000 is a video game console that was manufactured by Amstrad. It was the company's short-lived attempt to enter the games console market. The console was released in Europe in 1990 and was an upgraded design based on the then still-popular CPC technology. The GX4000 shared hardware architecture with Amstrad's CPC Plus computer line, which was released concurrently. This allowed the system to be compatible with the majority of CPC Plus software.
Amstrad Computer User was the official magazine for the Amstrad CPC series of 8-bit home computers. This monthly publication, usually referred to as ACU by its readers, concentrated more on the hardware and technical side of the Amstrad range, although it had a small dedicated games section as well.
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.
The Sharp MZ is a series of personal computers sold in Japan and Europe by Sharp beginning in 1978.
The Timex Computer 2048 or TC 2048 is a 1984 computer developed by Timex Portugal, at the time part of Timex Sinclair. It was based on the Timex Sinclair 2048 prototype, with a similar redesign case, composite video output, Kempston joystick interface, and additional video modes, while being highly compatible with the Sinclair ZX Spectrum computer.
The ZX Spectrum's software library was very diverse. While the majority of the software produced for the system was video games, others included programming language implementations, Sinclair BASIC extensions, databases, word processors, spread sheets, drawing and painting tools, and 3D modelling tools.
Vector-06C is a home computer with unique graphics capabilities that was designed and mass-produced in USSR in the late 1980s.
The BBC Microcomputer System, or BBC Micro, was a series of microcomputers designed and built by Acorn Computers Limited in the 1980s for the Computer Literacy Project of the BBC. The machine was the focus of a number of educational BBC TV programmes on computer literacy, starting with The Computer Programme in 1982, followed by Making the Most of the Micro, Computers in Control in 1983, and finally Micro Live in 1985.
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 memory and expandability. However, a home computer often had better graphics and sound than contemporary business computers. Their most common uses were word processing, playing video games, and programming.
The Amstrad CPC character set is the character set used in the Amstrad CPC series of 8-bit personal computers when running BASIC. This character set existed in the built-in "lower" ROM chip. It is based on ASCII-1967, with the exception of character 0x5E which is the up arrow instead of the circumflex, as it is in ASCII-1963, a feature shared with other character sets of the time. Apart from the standard printable ASCII range (0x20-0x7e), it is completely different from the Amstrad CP/M Plus character set. The BASIC character set had symbols of particular use in games and home computing, while the CP/M Plus character reflected the International and Business flavor of the CP/M Plus environment. This character set is represented in Unicode as of the March 2020 release of Unicode 13.0, which added symbols for legacy computing. The three missing characters have however been accepted for inclusion in Unicode 16.0 in the symbols for legacy computing supplement.
