But what should that project be then?
ATM no one can't really do any AOS4.0 specific HW, because of the lawsuits. So the only option is to turn towards "classic" OS and HW.
It can be done, as already proven. And with NatMai it can be done and improved on a lot.
So the way I see it, for hobbiest the only way to move forward is to use and improve on classic amiga hw/sw.
I might be wrong though..
