/* Requirements */
The core of the OS itself is executed directly in (Pseudo-)ROM or [[Dobbertin EPROM 224|EPROM]] (in four 16 KB blocks). It jumps between the ROMs with the help of a little common area. Therefore the numbers of the four 16 KB ROMs are hardcoded.
'''FutureOS''' uses 2 KB (&B800...&BFFF) of the first 64 KB; the rest of the remaining RAM is available to applications. Additional RAM can be reserved for DIRectory buffering. Furthermore the OS uses memory management(up to 4 MB), file-handling and specialized Low/Mid/High-level routines to access the hardware.
'''FutureOS''' can be launched from AmsDOS with the RSX commands |OS or |FDESK. If you use |FDESK you can leave '''FutureOS''' and get back to BASIC where you have stopped before - the first 48 KB (not the screen) have been preserved.
'''FutureOS''' only runs well on a [[CPC6128|CPC6128]] or 6128plus (not CPC464 or 664), because of their support for RAM configuration C3 (essential for the mouse pointer). FutureOS is not compatible with native [[AMSDOS|AMSDOS]] or [[CP/M|CP/M]] programs.
