The core of the OS needs 64 KB ROM. Compatible products are EPROM-cards, the ROM-RAM-BOX, Symbiface, RAMcard or similar products. If you don’t own such a card, you can take a look at FutureOS by using a very precise CPC Emulator (WinCPC, Caprice, WinApe).
The core of the OS itself is executed directly in (EP)ROM where it is divided in four 16 KB blocks. It jumps very fast from ROM to ROM between the ROMs with the help of a little common area. This has the advantage that So all the RAM of your CPC is saved for applications and data. Furthermore it allows efficient contains memory management, and file-handling and it brings high system stability (a virus or harmful code is not able to infect ROM J). Under From AmsDOS/Basic you can start FutureOS 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 64KB have been preserved.
FutureOS only runs well on a CPC6128 or 6128plus, because they support the RAM configuration &C3 (which is essential for the mouse arrow of the GUI).
