/* Requirements */
The core of the OS needs 64 KB ROM. On the CPC6128 it needs a ROM expansion or similar. Compatible products are EPROM-cards, the [[X-MEM]], [[MegaFlash]], [[Inicron ROM-RAM-Box|ROM-RAM-BOX]], [[SYMBiFACE II|SYMBiFACE II]], [[Ramcard 128|RAMcard]], Jareks [[CPC.Flash|Flash-ROM]], [[MegaROM]] or similar products. If you don't own such a card, you can take a look at '''FutureOS''' by using a compatible CPC Emulator ([[JavaCPC|JavaCPC]], [[WinCPC|WinCPC]], [[CaPriCe|Caprice]], [[WinApe|WinApe]], [[!CPCemu|CPCEmu]], [[Arnold]], [[Sugarbox]]) or others.
The core of the OS itself is executed directly in (Flash-)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 and the jumps are very quick. Applications like ROManager can change all that numbers. Parts of the OS can be loaded from media on demand if needed. Examples are the multitasking manager Caruh and the UI/menu framework CBM.
'''FutureOS''' uses 2 KB (&B800...&BFFF) of the first 64 KB; 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.
