The biggest issue with this idea is that the Pi uses 3.3Volt IO and the Amiga uses 5V IO... You would need a bunch of level shifters between the two devices... Also once you have connected the Pi, there really wouldn't be any need for the Amiga
If the amiga can use a powerpc accelerator, I don't see why it couldn't use the arm processor on the pi as an accelerator.
It would be tricky, but an interesting project. Better yet, 4 pi's networked
to the amiga with access to all cpus. All jammed inside an amiga 600.
