LocoScript was the principal software included with Amstrad's PCW 8256 and PCW 8512, both of which launched in 1985. LocoScript did not run under the control of an operating system, but, instead, it "was" the operating system: the computer was booted from the LocoScript floppy disk, and LocoScript ran exclusively on the system. The user had to reboot in order to run any other program (a variety of CP/M applications were supplied on a separate disk). In later years a third-party utility called "Flipper" eventually became available, restricted to those PCWs with the greatest RAM memory, which could divide the bigger memory between LocoScript and CP/M, allowing both to run without the need to reboot.
