The Amstrad PCW series (''Personal Computer Word processor'') was United Kingdom company Amstrad's versatile line of home/personal microcomputers pitched as a complete, integrated home/office solution. Some models were also affectionately known as Joyce, especially in Germany; the name is that of a secretary of Alan Sugar, the founder of Amstrad, and was the codename of the machine while it was in development. ==General features== The PCWs came as complete setups bundled with a full-size word processor keyboard, high resolution monochrome CRT monitor, printers of various types, 3" or 3½" floppy disk drive(s), LocoScript word processing software, and the CP/M operating system, including the Mallard BASIC dialect of the BASIC programming language. The machines were built around the 8-bit Zilog Z80 processor, running at 4megahertz, and managed the relatively large amount of random-access memory main memory using a technique known as bank switching (allowing access to more than the Z80's normal 16-bit address bus reach of 64KB). Although the PCWs were not at all designed as computer game machines, some games were in fact released for the platform, including such titles as ''Batman (Z80 computer game)'', ''Head Over Heels (computer game)'', and ''Bounder''.
==PCW models== * The PCW8256 or Joyce (1985) featured 256 kilobytes of random-access memory and one single-sided floppy drive that could store 180 kilobytes on each side of the disk (the disk had to be turned over, "flipped", to access alternate sides). The 8256 had a green screen monitor. * The PCW8512 or Joyce Plus (1985) came with 512KB RAM and two floppy drives, the second of which could store 720KB on a double-density floppy without needing the disk to be turned over. * The PCW9512 (1987) was supplied with a daisy wheel printer instead of the 9-pin dot matrix of the 8 series. It had a single 720KB floppy drive, and a white-screen monochrome display. The visual appearance was significantly changed. It came with a parallel printer port as standard. * The PcW9256 (1991) had a modern case design similar to the 9512, but had 256K RAM, a single 3.5 inch 720K floppy drive, a dot-matrix printer, and no parallel port. * The PcW9512+ (1991) upgraded the 9256 by offering 512K RAM and the choice of a daisywheel or Canon Bubblejet printer. The parallel port reappeared. * The PcW10 (1993) was a 9256 with 512K RAM and a parallel port. * The PcW16 (1996) was a radical departure from earlier machines. The Z80 CPU was retained, but ran at 16MHz. The system supported 1.44MB 3.5 inch floppy disks, and came bundled with an entirely rewritten GUI software suite and a mouse. It did not, however, come with a printer, and nor did it run software designed for the earlier machines. ==Market impact== The PCW series was extremely successful in addressing its particular market. These machines were not sold as general-purpose computers but rather as simple word processors. They were not bought in preference to a IBM PC compatible or an Amiga; but rather in preference to an typewriter#electric designs. Despite this they were capable microcomputers which were used for database management, online services, spreadsheets, programming, and even graphics and desk top publishing. They introduced a generation of British writers to computing who might not have otherwise become involved with them. ''See also'': Amstrad CPC Personal computers
