'''FutureOS''' only runs well on a [[CPC6128]] or 6128plus (not CPC464 or 664), because they support the RAM configuration &C3 (which is essential for the mouse arrow of the GUI).
== GUI ==
The Desktop of FutureOS is divided in two sections. First an icon-section, where you can choose your functions. Second there is a section below, where you can browse through directories of discs and hard-disc partitions.
The Desktop can be controlled using a joystick, mouse, trackball or light-pen. There is no command line. The user interface is graphical, you click on icons and files to select them for subsequent actions.
Applications can call the GUI as a subroutine. The icons are fixed, so you will always work with the same desktop. == CBM == Aside the ROM resident GUI there is another surface for FutureOS, the command bar menu CBM. It consists of several flexible pull down menues and file selectors. You can easily use CBM for your own programs. Since all programs that use CBM look similar its also easy to use different programs really intuitive.
