Dominant future AmigaOS? MOS vs OS4 vs AROS

[AmiGR]

The problem is that most ex-Amiga owners, will either
say "The Amiga is dead, bury it" or "Amiga? AHAHAHA, Commodore, then Escom, then HAHAHA,
Gateway, LoL!"

That's what happens in Greece with most people.
Here, the Amiga was dominating 13-12 years ago.

[AmiGR]

Actually, say MOS "was" inferior Ambient-wise.
MOS1.3 is old already, 1.4 is about to be released
and its Ambient is much more useful.

Nahlepuh and stuff like it are mostly MMU hacks.
Such MMU hacks are not even considered, as they
will slow down everything significantly. Every poke
to Paula would produce MMU exceptions that would
have to be handled with multitasking disabled.
Such stuff have no place in a clean OS.
The goal with both solutions is not only to produce a
compatible and extended OS but to clean it up as well.

[AmiGR]

It's silly for one reason... The one who dominates the
Amiga market is NOT the winner. Every team will start
targeting other markets, thus following other paths.

MOS... Amiga Inc part two... and these guys don't even have a name they can live off of.
--

They don't have THE name, but they do have 10(100?)
or even more times more money than Amiga Inc, have
a plan and have the connections. They even have the
connection to get a very good name (that will let many
people down)  and many stuff that come with that name,
for the last few years. Take a look at www.morphos-news.de...

[AmiGR]

You ignored half my posting...
Take a look at morphos-news.de and morphzone.org
to see which name I'm talking about.
And no, this is no joke, they have the connection to get it.

Did you forget 68K CPU emulation? One could use sound blaster emulation within WinXP’s dos box as another example.
--

Depends on the implementation. For example, MorphOS uses emulation traps instead.
Newbaer uses the mmu stuff outside of the emulation box, on the linux side.
It still slows stuff down, but on a 2ghz machine it's not visible.

[AmiGR]

And what if I tell you that that's their connection? :-)

[AmiGR]

I'm not talking about any rumours...
Yes, Infogrames uses the Atari name.
The connection to get that name *IS* Infogrames.
Ask BBRV for more info, I can't say anything without
his consent.

[AmiGR]

LoL! Didn't notice that mistake he did, Jay was CERTAINLY not "minor" ;-)

[AmiGR]

It that for audio (Paula compatible) or the 68K CPU?
--

68k.

In regards to speed, it’s fine on 1.33Ghz Athlon model 4. Also, it can’t be slower than WinUAE-JIT, i.e. emulates the entire Amiga Classic ecosystem.
--

Well, as I said, on Amithlon, it's done externally afaik.
Such stuff have no place in a cleanly made OS.
About UAE now, that emulates the whole, synced,
environment and speeds the whole thing up to become
faster. That's not how it could work on a native OS.

[AmiGR]

Well, the problem is that all Paula using proggies, just bang it directly, without going through audio.device.
To make them work, you need a way to find out when a proggie tries to access the Paula registers,
this can be done via the MMU, by setting us a virtual
paula register setup there. Any access there would
cause a nice MMU exception, disabling the multitasking
for a while, that would have to be
passed to the emulator. That would slow down the
system a lot if it's not done in a careful and sufficiently dirty and hackish way.

[AmiGR]

It’s a matter of the current implementation.  Unlike X86 world, skill sets, manpower and financial support is in short supply within the Amiga land.
--

Actually there are quite some skilled people in here.
The problem is that such stuff take time and it would
require strict understanding to do such tasks with
big teams.

I recall, AmigaOS 4.0 reserve some address space for this kind of problems? It’s probably incomplete at AmigaOS 4.0 state.
--

Yep, but we'll have to see how it works. It sounds that it will slow the system down, but we'll really
have to see that in practice.

Does MorphOS 1.3/1.4 handles any audio.device issues?
--

There's an audio.device replacement but the
problem is that most apps that open up the audio
device, allocate the channels and then just bang
paula. No Paula emulation is there and it's not planned.


 Does MorphOS 1.3/1.4 handles any CIA resources issues?
--

It does handle the interrupts but that's it. Chipset
emulators are generally not there.

AROS is an Open Source reimplementation of AmigaOS 3.1, adding many features to the API.
MorphOS is a modern AmigaOS compatible OS that
extends the API quite a lot and had many stuff
needed in AOS for years. It shares some code with
AROS. It's released right now.
OS4 is the official PPC AmigaOS update that does
pretty much the same as MOS, but was started much
later, uses a different implementation and is not out
yet.
About differencies to the user interface etc., I'll have
to see OS4 before I comment.

[AmiGR]

Well, most up to date apps work, anyway. The
software bundle will have replacements for some
other needed stuff.
We'll see how it unfolds.
It's not as if it's not possible in MOS, they don't wanna
do it, for speed reasons and in order to keep the OS
clean. It could be implemented by a third party, like
on AmigaOS, for example.
