* No AMSDOS or other DOS in ROM, only a bootloader for CP/M
* No support for tape recorders
* 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. Furthermore, the boot code in the PCW is stored in the printer controller.
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.
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.
