Thomas has a good point here. I have to agree with him.
I'm not sure if we did express the point well enough.
Maybe someone with a better english can do this better.

So what is the point about the AMIGA?
The point of the AMIGA was that it had two things:
A powerful and highly efficient DMA driven Chipset
and
A fast and slim Operating system: Which made extensive and hgihly efficient usage of the AMIGA chipset

This was unique.
Where was the difference between the AMIGA and the ATARI?
The CPU on the ATARI base model was even clocked higher than on the AMIGA.
So why where the games better on the AMIGA?

The AMIGA was unique to have this DMA driven chipset.
The AMIGA OS was unique to always use the chipset.

The new systems like AMIGAONE do not have an AMIGA chipset anymore.
Therefore OS 4 or AROS can by desing not make useage of a chipset.
This means they have to do every work (small or big) using the CPU.
And in this regard OS4 is now more like ATARI than AMIGA OS.

Yes OS 4 is slim, but by design it can not behave like AMIGA OS - in using the underlying Hardware to its full extend. Simply because the PowerPC Neo-AMIGAs are not designed like an AMIGA was but like a PC.

For the same reason OS 3 is faster.

OS 4 might be nice for a Classic A3000 with PowerPC card.
This classic A3000 has an upgraded CPU but his chipset is still very old - so not fully using this old chipset is not such a major loss.

With the Natami the story is a lot different.
The point of the Natami is to update the orignal AMIGA chipset.
The Natami chipset is AMIGA compatible but provides magnitutes more performance. Making full usage of the chipset opens a complete new ballgame again.

Was this clear?

Some would even front page it!

-Amiga OS, 3.9 this is a no brainer(I am not sure if kickstart allows lower versions then 3.1, this is my lack of knowledge)
-AROS or atleast a 68K release of it. (This isn't fully true for it wouldn't know anything of the chipset)
-Minix, the older versions newer need a MMU, (could try to take it up with the creator of the Magic1 CPU)
-A homebrew OS make especialy for the Natami.
-CP/M (with some tweaks)

Not supported OS's

-Windows (Ew, who would want to run this c*** on the Natami?)
-DOS (Copyright protection, but otherwise CP/M Clone)
-Linux (This is due to the fact that every Linux build needs a MMU)

I am sure i have missed a lot but this is just a short list.
I am not advocating the use of other OS's on the Natami, all i do say it's posible to use others.

AOS 4 is an odd duckling, Copyright is holding enthusiast back from making a port themselfs.
Let's hope that the AOS 3.9 source in the near future gets released as freeware.

Please don't forget about very interesting project which is AfA OS (Aros for Amiga).

"Let's hope that the AOS 3.9 source in the near future gets released as freeware."

Well, if it was possible to buy back rights to Blender prototype, why not to buy off Amiga OS 3.x rights (any, perhaps even 3.0 would do) as a community?

Take care.

Good idea. Very good idea!
But whom to ask?

"I for one would gladly contribute financially to a buyback of the OS 3.x source with the goal of releasing it under an open-source license."

Now you are talking! Look at it this way, Natami will de-slave us from the hardware side. a purchased-then open sourced 3.x will de-slave us from the OS side. All that would be left was to deal with Kickstart. This would give 68K Amiga a life of its own again.

I would also gladly contribute financially to a buyback of OS 3.x source.

Well, I don't know. But I know that it might be possible to benefit from that unclear (in terms of copyrights) situation and strike now. The question is how to do it right...

Regards.

I totally disagree about funding AROS.

If we had $100,000, far better to throw it at a big production run of NatAmis.... of course that leaves up in the air having a fund for buying AOS3.x source and ROM code. :-((((

If anything, I'd rather that Hyperion just write a new version of AOS3.x 68K. Again, it doesn't have to have parallels to AOS4.0, AOS3 would maintain it's own identity, tied strictly to ECS/OCS/AGA HW.

1 Amiga OS4 includes an extended API, so programs written for Amiga OS4 are not source compatible with previous versions. It also includes a form of POSIX emulation (I recall reading somewhere that this was started in AmigaOS 3.0, but I might be wrong).

2 Amiga OS4 supports multithreading and ressource tracking.

3 Amiga OS4 includes some major usefull updates such as imporved filesystems, as well as useless ones such as memory protection, swappable virtualised memory, and so on.

4 Amiga OS4 includes a whole set of tools which have come to be regarded as standard on an operating system such as, for example, a text editor or a software to view PDF files.

5 Amiga OS4 comes with high end commercial software such as, for example, Page Stream.

6 Amiga OS4 has many other changes in the design to help it run on the AmigaOne type of computers which are of no interest to us.

Let's see how the above mentionned features which are usefull without the problems inherent to bringing Amiga OS 4. I will answer to each using the same number as above.

1 Maybe, AmigaOS can be patched to allow the existances of subsystems, and have the OS4 API and the POSIX API implemented as subsystems, maybe someone who is more familiar with the operating system design can say more about this.

2 I see only two options, either have Carl Sassenrath or someone else write a new version of exec with ressource tracking and multithreading or forget about it. I see no other choice. Also, I recall having read that multithreading only gives a speed benefit on some types of processors, I don't know if the if it would be usefull on a 68k.

3 We can port a driver for an advanced filesystem from AROS, the useless features are best not implemented. This, with the subsystems mentioned in #1 as well as extra datatypes and possibly other usefull libraries can be combined in releases called NASE (Native Amiga System Extensions), which would have its own version number.

4 Most of the needed tools are available from Aminet. I however understand the use for having such tools as standard. I therefore suggest creating and making releases of a thing called NAPE (Native Amiga Platform Extras, the name alludes to both the NatAmi (Native Amiga) and the Extras disk of the traditional Amiga operating system (Extras)). It would be a complement to the operating system, which brings all necessary tools for a modern working environment in which all tools would be checked so they work with the version of the libraries supplied with the NatAmi and so on. A global tool to install the programs composing NAPE would be usefull too. I would suggest making NAPE releases based on tools from Aminet. Things that should go in NAPE would be software such as a lha archiver, a text editor, a ftp client, a calculator, an icon editor, maybe a terminal client and a PDF viewer, etc.. Having it as a seperate release from the system also helps keep the operating system small.

5 I strongly suggest creating a StarterKit made of commercial software to go with the first consumer version of the NatAmi (included in the final sale price), this would be good for the developpers since they would do bigger sales than otherwise, good for the users since they would get a great software pack at a better price than otherwise (mass sales bring software at lower prices), and good for the Amiga community as the money of the mass sales would be an incitation for the developpers to write some more software titles.

To summarise, with this approach, a standard environment on the NatAmi would be composed of three parts:

1 The System: the plain old operating system which would stay the same over the time
2 NASE: the extensions to the system with occasional releases, tailored to the NatAmi, bringing source compatibility with POSIX and OS4; datatypes and so forth.
3 NAPE: a set of tools that run under the system with NASE and which bring a modern working environment to the platform.

Patching/improving 3.x for Natami makes sense, since there is already much done for it and it is tailor made to run on the classic chipset.

Supporting AROS for Natami/68k makes sense, since it is open source and has a secured future, and is looking really promising at the moment. Supporting the free kickstart effort would relieve the community of old legal ties and make a lot of projects easier.

Expecting a small Belgian company to release their proprietary OS with a really limited market for an even obscurer platform when they don't have the resources to port it to x86 does not make sense. Hiring Carl Sassenrath to write a modern exec? I mean, we can all dream, but this is totally unrealistic.

Sometimes I feel like peoples attitude towards OS 4 is all about the name and the logotype. I mean, I run 3.x, OS4.0, MorphOS 2.0 and AROS systems, and it's not like any of the nextgen OSes are more "Amiga" or less "Amiga" than the others. I don't care what they are called, but what I do care about is survivability and flexibility.
For example, if Hyperion goes bankrupt next year, what would happen with OS 4?

OS 4 for Classics being made to run on f.e. a PPC expansion for Natami would be a cool extra feature, but I don't think relying on OS 4 as some kind of future main operating system for the Natami makes any sense at all.

But whom would we need to contact regarding this.
We owns the right to AMIGA OS?

I heard that there is some working on this.
Do you think that we as Natami/AMIGA community can help in this?

EXTERNAL LINK 
I agree with the Natami Team's position on using classic Amiga OS. Before we get off track in alternative OS's let's at least focus on creating a working viable system with AOS 3.9. After that who knows?

I think this contact form on the AMIGA website does not work.
I used the contact form before and got no answer.
