Yes. Fortunatly he is looking at possibilities instead of rejecting it at first hand.
You think I am making this up and didn't look at the specs before rejecting it? Also, isn't this kind of backward thing to do: First create the HW around some CPU and then try to figure out if it can be used at all?

we can trap all FPU instructions

That should work, assuming the other differences can be handled in a similar manner. It remains to be seen what kind of performance impact it might have. WarpUP-WarpOS/Demos/cybermand will be the judge of that I guess.

As I recall it for some reason WOS exposes the supervisor side of the CPU to any apps though (Super() call). Hopefully that isn't used much.
