Errmm.. wait. First of all, everybody should know by now that I believe the PPC was about the worst thing that could have happened to the Amiga (mostly because of that red vs. blue war). However, I have the highest respect for the OS4 team and Gideon - I do believe that both have the required skills to make it happen. However, Gideon obviously chose to spend his spare time in a different way. Now the OS4 team is on the same CPU, and I am pretty sure that they wouldn't have started this work if there's no perspective for success.

Coldfire? That's a totally different story. There was only one person on it, and he chose to do what he could do a lot better: Stay within his core business (to deal with boats if I remember right). In other words: There was never any serious effort to use a Coldfire processor in the Amiga. That's "for good reason" in my opinion: While the Coldfire attempts to be binary-compatible, but behaves differently on *implemented* commands, the OS4 core team member I talked to claimed that implemented FPU commands work as they should, and unimplemented commands throw an exception. Although I haven't read any details in a datasheet, I trust Cosel Mincea on this: The P1022 may have an FPU with fewer commands, but it also provides the bits&pieces to work around that, just like the 68060 did.

Sure - but in a different thread, please. This one is about Tabor - something that has all chances to become a working alternative for OS4.
