All models except the last included the Locoscript word processing program, the CP/M Plus operating system, Mallard BASIC and the LOGO programming language at no extra cost. A wide range of other CP/M office software and several games became available, some commercially produced and some free. Although Amstrad supplied all but the last model as text based systems, graphical user interface peripherals and the supporting software also became available. The last model had its own unique GUI operating system and set of office applications, which were included in the price. However none of the software for previous PCW models could run on this system.
