Sonnet crescendo 7200 and OS4.1

[Rob]

Can you point me to technical info on that?
It doesn't sound like they had the resources to realize it, but the idea sounds practical.

I wasn't really paying attention to the Amiga community at that point.
All I've heard about that project merely made it sound like a scam, but a "pointless brainfart"?
What seems pointless, is that when you tack a PCI bus onto an Amiga everything is coordinated via a bridge to the much slower native bus.
Why not have a direct PCI connection to the PPC cpu?

This article translate from French gives a good overview over the project and how things panned out.

You may have already seen the schematic before on the Phake5 Facebook page.

Does  Tundra Semi still support and supply the mpc107/tsi107?

They're defunct.
