'''FutureOS''' only runs well on a [[CPC6128|CPC6128]] or 6128 Plus (not CPC464 or 664, except you have a RAM expansion with full RAM mode &C3 support like the one from Revaldhino), because of their support for RAM configuration C3 (essential for the mouse pointer). FutureOS is not compatible with [[Firmware]] or [[CP/M|CP/M]] programs, but supports their data structure. It needs a [[Class]] 2 CPC, it runs best with a [[Class]] 4 CPC or higher.

'''FutureOS''' does not require the native CPC-OS(neither BASIC, DOS or firmware) , except its character set. If you replace the lower ROM by the [[CPC FutureOS lower ROM]] for example, then FutureOS will start directly. You can use your own set of characters.
There is a Cartridge version of '''FutureOS''' which supports some Plus features.
