More like not supported by Amiga OS4. Xena (the onboard XMOS), Xorro (the proprietary hardware slot), on-board sound chip, on-board ethernet chip,...etc. Although some of the on-board components were supplemented with add-on cards, I can't find the specifications for these components.
Correction, the on-board sound
is supported, so you can cross that off your list. The ethernet driver is still being beta tested and, yes, a plug-in card provides networking capabilities in the meantime.
I'm not sure what sort of support you're expecting for Xena & Xorro. Those two items are primarily for developers to play with. It's up to them to create something more useful than just
flashing an LED. Developer tools
are available, although last time I checked they were still pretty minimal (i.e., enough to get started). Likewise, a
Xorro developer board is available for those who wish to design boards for this slot.
Which brings me to my next point: why would anyone be dumb enough to develop and waste money for on-board components that aren't supported only to have to use add-on cards in place of those components (further increasing the cost of the system)?
Most likely because development of the drivers for those components proved to be more difficult and take much longer than expected. Providing substitute cards meant that those difficulties didn't further delay the release of the board. It's a compromise.
A-EON may well wish that they had done certain things differently, but at least they're doing something instead of just talking about what should be done and criticising others.
