Welcome to A.org,
Not many here can make the claim to have successfully booted AOS4 on their PPC MacMini!
Your talents could certainly be useful in helping complete the port of AOS4 to the PPC MacMini so that it does more than just boot and is actually fully functional and useful, just like the MorphOS team is attempting to do.
It would/will be great to have one readily available, relatively cheap hardware, that is capable of running both MorphOS and AmigaOS faster than any currently available offerings.
