Amigamia,
Are you near the DC Metro area? I'm in Silver Spring, MD. Let me know if you need some help building an Amithlon machine. I have built several from free computers I've picked up.
I'm also interested in setting up a site for Amithlon support from my experience with the product.
I believe it's probably the best of the modern Amigas (Amithlon (OS3.9), AmigasOne (OS4), Pegasos (MorphOS)).
Like the other modern Amigas, Amithlon does not support the old custom chips directly. It uses retargetable graphics (P96) and audio (AHI).
But it is more compatible with most Amiga software since it can run 68k code using very low-level JIT emulation. OS4 and MorphOS must use E-UAE since they are PPC native.
Also, hardware is plentiful and cheap. People are getting rid of their 5/6 year old computers which are ideal for building Amithlons.
And finally, you can install Amithlon on much faster machines. Both the AmigaOnes and Pegasos machines are already several years old. As Gary Colville, and perhaps others, develop newer kernals, it can support newer hardware that the others can't.
