Well, PA6T - the wrong horse to have bidded on? I've said so and I say so now. The chip was interesting fom its specs, but it is dead like a dodo.
It being "dead like a dodo" is irrelevant as long as they have a sufficient supply, and given the size of the Amiga market that doesn't take much.
The reason it's irrelevant is that most of the PPC chips that are potential candidates for AmigaOne hardware in one form another are SOC's that are not socket compatible from version to version.
In other words, you're faced with redesigning the board for the next generation anyway, in which case it matters a whole lot less if you need to switch to a CPU from another source.
