'''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 at all (neither BASIC, DOS or , nor firmware) , except its . The only exception can be the character setof the lower ROM. If you replace the lower ROM by the [[CPC FutureOS lower ROM]] for example, then FutureOS will start directly. You In this case you can use your own set of characters, just put it between &3800 and &3FFF in the lower ROM.
There is a Cartridge version of '''FutureOS''' which supports some Plus 6128plus features.
