I'm guessing Petunia is the OS4 68k emulator? How does it perform compared to a real 060/50? And I'm also assuming that blacklisting it will make it run using the real 68k CPU instead of the emulated one?

I doubt it, I can't see how OS4 could use the real 68k... I expect it falls back to an interpretor, which probably supports more CPU features!

Why shouldn't it? OS3.x is a 68k OS and can access a real PPC processor, so why shouldn't a PPC OS be able to access the real 68k processor?

Actually OS3.x can't access the PPC, which is why you need to have another kernel running in parallel, i.e. PowerUP or WarpOS. Those two old solutions were terrible, the currenlt OS4 approach (which is similar to the original MacOS PPC/68k approach) is a much better idea!

@Akiko
Hmmm, that may affect my decision about whether to upgrade, since I use my Amiga mainly as a classic games machine.

If I were to be mainly using my machine for games... I'd not bother with either a PPC or an OS upgrade... it yould be more fun to get a couple of second hand A500's instead and run all the machines at the same time :-D

Ahhh I see. For some reason I always thought that PUP/WOS were optional extras. I understand your point now. By that reasoning, could a 68k kernel run alongside OS4 to allow access to the real 68k processor?

That depends upon how OS4 is designed... but any solution like that will cause all the same problems that WOS and PUP had... Running 603 and a 68k on the same bus and trying to get them to communicate is just a nightmare! They can't really run at the same time...

I know you're probably right. But I want OS4. I don't know why - I just do :lol:

Yes, my BlizzPPC and Bvision certainly would like to run OS4... but I can't justify it at this time. To be fair I can't really justify keeping my PPC Amiga set up any more :-(

At the same time, you say? :crazy:

Fair enough. Looks like the developers made a good call disabling it.

Yeah, I think so... It's a shame Phase5 even put a 68k on the board at all... Instead, it would have been better if they had just run a 68k Emulator as a task on the PowerUP kernel and run AmigaOS in emultion.

You don't have to - you've already got it. I'm trying to justify buying one :-)

But watching the price these boards are going for is making my PPC and BVision combo an asset I can't really afford to keep... especially since I really don't need them any more... The only thing that keep me hanging on is sentimental value!

You are right!  sell it to me :-)  and iff you want.........I will sell it back to you in 2 years........

The thing is, my A1200 is all I really have left from my Teenage years... so I cling to it with an unhealthy obsession.

It's cos all classic games and demo's which banged the hardware directly would not have worked.

It was the best and only call to make back then.

Note: It is still true today. AFAIK OS4 cannot run the majority of classic games, demos, WHDload etc. because the 68k CPU is completely disabled and the 68k emulator doesn't interact with the classic hardware to the level needed. A reboot to OS3.x is required :-(

But those Games/Demos would run fine on the 68020 already in the A1200... Just disable the PPC card when you don't need the CPU power.

It means you have to reboot, run the game or demo and then reboot. Not very user friendly.

If the Game/Demo hit the hardware in such a way that it couldn't use an emulated 68K you would have to reboot anyway...

Anyway, point well made... One could simply run MorphOS for Classic Amigas... that is Free, right? Ok then!

Running UAE on a BlizzPPC is a very traumatic experience and not one I'll bother to repeat!

I think you know the answer!

But this wont work on the classic as it is too slow.

So what to use OS4 for ? Instead of still use 3.9.

My personal preference would be AfA on OS3.x... With the current rate of AROS progress, it holds a large degree of excitment for me!
