Excuse my ignorance, but why is a port of OS4 to Pegasos necessary anyway? The problem, as I see it, is potential incompatability with OS4 with future apps, not OS4 itself. Morphos currently looks like a better environment than OS4 does. As long as it can run the same apps, who cares?
The Morphos team went to all the trouble to reverse engineer the 68k AmigaOS, can't they do the same with OS4? Isn't all the information required, ie the API etc, all available as part of the OS4 SDK. Theoretically they could begin now that the pre-release is out. With a bit of effort Morphos could be more OS4 compatabile than OS4. :-o
I admit, I could have this entirely wrong. So I'll shut up now. :-?
