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).
== Supporting it all Support ==The idea of FutureOS was not only to develop a fast, easy programmable an OS which is able to deal with big files and applicationswhile being easy to program. One point that lead to the development of FutureOS Another idea was the wish that it should be possible to support all any hardware (ever made for the CPC) with just one OSavailable. Remember, For example there are 3.5” B-drives, Vortex F1-D-drives, hard-discs, real-time-clocks, serial interfaces and much moreetc. Every piece of hardware has its Hardware expansion usually need their own software drivers (DOS on Eprom, drivers or whatever). Sadly all these software packages for expansion hardware aren’t compatible One of the future goals of FutureOS is to provide access to different expansions under AmsDOS Lone roof.
FutureOS was designed is planned to work with all known hardware expansions for the CPC. You can It sould be possible to use a 3.5” B-drive, external Vortex F1-S or F1-D, a serial interface (or two!), different RAM expansions and maybe a hard-disc (Dobbertin HD20 or CPC-IDE; CPC-IDE since system .9). All that is reported to work properly together.
Most of the low level system resources can be accessed freely, e.g you can use interrupt mode 1 or 2 (standard under FutureOS). Using IM 2 is mandatory when designing expansion hardware.
