What for does OS4 NEED an MMU?

It also set some of the memory Read Only to protect Kickstart modules..

Drivers even setup memory pages to be cache inhibited..

and then there is also support for Swapping out memory..

So AOS4 do use the MMU... but if Vampire has a working MMU then I stand corrected.

if you want to backport AmigaOS4 you can do it with missing FPU as that can be software emulated... that is no possible if MMU.

That misses the point entirely.

We have email, social media, telephones and three-eyed crows that deliver messages. That's what can be done about it.

The Vampire is giving legacy systems modern capabilities and the user base will almost certainly eclipse that of the two classic PPC accelerators. Ten years ago, PPC was the only option.

If the market is there, all of the other challenges quickly melt away.

And... I'm sure a lot of people didn't consider the Atari community as a potential channel for the Vampire either and now look. TOS certainly wasn't a "genuine" Amiga OS. Who cares?

yes. apparently atari people do. and they have an open source os. good for them.

now, people behind os4 obviously dont. they told it again and again, they have their dedicated hardware, and it is both faster, which they like to stress, and brings more revenue. you are free to contact them and check this all yourself.

if you want one to certain extent more advanced and open source os, which is compatible with your amiga application there is aros. it remains even to be proven how compatible and fast os4 native on 68k would be if ported, since it always used emulation for 68k programs. with aros this is known.

so, if you really intend to get os4 running on a vampire, go ahead, nothing against it. its simply very unlikely.

This isn't about the community chiming in on technical feasibility or the strategic objectives of the players.

The question was simple: have channels been opened up to explore relationships with third parties?

At present, the answer simply appears to be no - and that's fine.

But one thing we do know for certain: the only way to truly know the likelihood of something is to communicate with the people involved.

Yes, even money was offered to Hyperion but they said they would take it and put it into PPC development.

Right... the power of negative thinking.

And if so, it pretty much tells us that OS5 needs to be a complete departure.

General commentary; Hyperion is having a hard enough time to deliver the basics they have promised/envisioned for AOS 4.2/PPC hardware, let alone transfering it over to 68k.
Basically it seems to me the raw number of developers competent enough to even dream about doing anything like you think about on a OS level, is too far and few between.

Thats my impression anyhow.

The OP asked about the possibility of 4.1 becoming available for the Vampire.

If Hyperion intends to remain focused on PPC, I suspect that 4.1 support is unlikely and that they would dismiss the idea in the same way that they have always dismissed support for other platforms.

I also believe that the likelihood of the OS evolving with them in charge is equally grim, meaning that 5.0 would be better off if it did not leverage 4.1.

We all understand that there are a limited number of developers capable of doing specialized tasks and that financial resources are often limited.

But... other projects find developers, other projects find money and other projects deliver.

I'm not suggesting that any of this is easy but perhaps it's time for change.
