The <b>PCW</b> (<b>P</b>ersonal <b>C</b>omputer for <b>W</b>riting) was another Amstrad computer. In Germany it's better known by its codename <b>Joyce</b>, which Schneider chose to keep for the final product.
The codename was the name of Alan M. Sugar's secretary.
The PCW was the Amstrad computer in production for the longest time(1985 - 1996). And the Amstrad computer with the most model revisions (Starting with the PCW8256 and ending with the PCW16PcW16). All models was based on the Z80 CPU.
The series consists of PCW was 8256 and PCW 8512 (introduced in some ways similar to the CPC range1985), but also different PCW 9512 (introduced in 1987), PcW 9256 and PcW 9512+ (introduced in 1991), PcW10 and PcW16 (introduced in 1995). The PCW switched from 3inch floppy drives to 3.5inch floppy drives in many ways1991.
8 million units sold worldwide (over 200,000 in UK) [https://www.retroisle.com/amstrad/pcw/general.php Source].
By 1989, 1.5 million units had been sold [https://en.wikipedia.org/wiki/Amstrad_PCW Source].
The Daily Telegraph estimated in 2000 that 100,000 were still in use in the UK.

== Design ==
The PCW was designed as a (back then) professional computing system. This was underlined by the built-in green monitor (no support for colour monitors at all), the bundling with a printer and a word-processing software and bigger RAM (256k or 512k).
Although the name might suggest it, the PCW was more than just a word-processing system. Unlike some other similar word-processing systems of its time, it came with a normal operating system, CP/M + GSX, and could run any software for this system, like spreadsheets, databases and so on.
<br>
== Market ==
The PCW had its biggest success in the UK, where it is even used up to today in some branches, e.g. small hotels.
In Germany, Schneider mainly marketed it as word-processing system, not outlining its usability for other purposes, so that professional users decided for IBM compatible PCs.
The PCW was in some ways similar to the CPC range, but also different in many ways.
<br>
== Similarities to the CPC ==
** disk drive
* Z80 CPU
* [[CP/M ]] Plus operating system <br>
== Differences to the CPC ==
* 90 columns, 720×256×2 graphics (actually possible on a CPC)
* No sophisticated sound chip (Beeper only)
* Joystick support through 3rd party extensions only (the keyboard controller includes support for two joysticks, as on the CPC, but no keyboard using this was ever built).
* No AMSDOS or other DOS in ROM, only a bootloader for CP/M
* It has a dedicated printer microcontroller: [[Media:UPD8041AH datasheet.pdf|NEC UPD8041AH datasheet]] [[Media:Intel 8041A Datasheet.pdf|Intel 8041A datasheet]]. It is disguised as Amstrad 40026 chip on the motherboard, but it is visible in the service manual for PCW 8256.
== Video Peculiarities ==*The boot code in the PCW is stored in the printer controller.*There are two versions of the printer controller: one for the 9512 and 9512+ (daisywheel printer), and the other for all other machines (dot matrix printer).*The two controllers provide different boot code, making the boot disks NOT interchangeable between the machines.*9512(+) runs versions 2.x of CP/M, other machines run 1.x. Don't worry, the only differences are the boot sector and the printer driver code.*The machines, including the PcW10, are otherwise entirely identical and use the same gate array.*PcW16 is a totally different and incompatible machine.
The operating system, called Rosanne, no longer uses a command prompt but has a true graphical user interface written by Creative Technology. It makes use of the included 3-button mouse. The resolution is now 640x480 instead of 720x256 for the other PCW machines. See: [http://toastytech.com/guis/pcw.html Amstrad PcW16 GUI screenshots] Memory is 1MB of RAM, and 1MB of Flash which contains the BIOS, Rosanne, and the built-in software: a word processor, spreadsheet, address book, diary/alarm, calculator and file manager. It is not supplied with CP/M. However, CP/M 2 and 3 have been ported to the PcW16 by John Elliott [https://www.seasip.info/Cpm/software/index.html Source]. The PcW16 does not come bundled with a printer, but provides a standard Centronics printer port. It has drivers for laser printers, inkjet printers and 24-pin matrix printers. It does not support daisy wheel or 9-pin matrix printers. <br> == Links Video == *[https://youtu.be/ClANdCoFpv4 From 80s to Today: Can my Sister still work our vintage AMSTRAD PCW?] by [[Retro Recipes]]*[https://youtu.be/oE1C3wFdiZU Amstrad PCW GUI!
