Sorry to redirect the subject of the thread a little bit, but what ever happened to the Natami project?
The developer of the SuperAGA chipset core was motivated primarily by learning to become a better developer. Once he achieved that goal, he decided that he didn't want to participate further in the project so he rage quit and since the entire SuperAGA core was his only, anything he had done is no longer legally accessible to the rest of the team.
The other core of the NatAmi had its name changed. The N68070 is now known as the Apollo core. It is still being developed by Jens, Gunnar and several of the other team members. The last I heard from them, they had developed an SIMD unit for it geared toward planar graphics and was in the process of making a simple planar graphics core to go with it with some added features.
There is also another hobby project on AmigaCoding.de that is being developed by Marcel Verdaasdonk (aka Veda) tentatively referred to as XCS. It is more elaborate than the simple planar-only graphics core developed by the Apollo team. It incorporates indexed chunky mode and byte-planar modes in both the deeper pipelined Blitter and display functions as well as caching and an eight-way multithreaded 32-bit Copper. It is intended to be used with the Apollo CPU core and although Marcel was not an official part of the NatAmi team, he posted to the NatAmi forum regularly.
As a former member of the NatAmi team myself, I'm putting my lot in with Marcel as a documentation editor since American English is my native language and not his. If all goes well, I'll come up with some AROS drivers to support his chipset core. (In particular, I'm looking forward to being able to queue blit-nodes via one of the Coppers instead of tripping interrupts on the CPU every time the Blitter finishes its work.)
