My experience jumping from SAM460LE to X5040.

Your cats seem to have found a nice comfy spot !

Gart RX/HD driver is available also for 460 and is working very well since months. Simply there is no public update of it but don't ask me why

@afxgroup

It's a great news for all SAM460 owners, better news when it's available. Congratulations for Hans, he resolve an endemic and historical problem with coherence caches in SAM systems.

We can add also the unreleased kernel fix for Pegasos 2.
AmigaNG Mysteries..

The mystery is simple; just like with the 68k, AmigaNG can now be emulated.
Luckily (for them), good hacking isn't interested in AmigaOS emulation.
Otherwise, it would have already been done.

Clearly, real hardware is always best for anything.

I really hope it will eventually make it to the surface (I wouldn't mind if it would be as a part of new ES version, AmigaOS 4.2 or simply a standalone product like RadeonHD driver). Definitely, it is a highly demanded and absolutely crucial piece of software for Sam460 users.

@Djk83
Sam460 users probably have it best of all AOS4 devices when it comes to updating their equipment.
I think it could always be worse if you bought the A1222+ under the influence of “marketing.” Zero nothing... not even a hint of an update.

@kikems

congrats I went from a Samflex@800 to X1000 and still enjoying the boost and waiting for the day we can finally use our extra core(s)

I don't want to take away your illusion of multicore support, but it's not just the kernel that has to provide this.

All the software we already use under AmigaOS 4.1 has to be multithreading-capable, and I don't think this is the case.

Two years ago, when I was starting to consider buying a native hardware for AmigaOS 4 and was gathering information, I got this odd feeling that people pay fair amount of money for their machines (which are brand new commercial products) but then have to rely on forums and community to solve any problems they may possibly encounter. While I really do appreciate the awesome community support (and this actually raised my interest in the topic even more!), I withheld my decision for a while because of this potential lack of support.

I don't have any personal experience with other machines and hence cannot comment on that, but certainly I'm very happy about how ACube approaches this. The support is there, and definitely Sam is alive and kicking! It's a great feeling, knowing that your favourite platform is under active development (such a convenience that with update 2015.d, finally I don't need to switch keyboards to access the UBoot).

Even if at some point in time I will choose to buy more powerful hardware, I will certainly keep my Sam460 with me.

At the same time, as long as the OS itself does not support multithreading, there's probably no motivation for developers to go that way. Correct me if I'm wrong, but I believe that once SMP support is there, the software utilising the new possibilities will start to emerge.

Right or wrong, I've carried the impression that the difficulty adding SMP support was because the developers were trying to make it work for legacy software. If it's a matter of bolting on new API's, I'm okay with that. There isn't such a mass of OS4-specific applications and games that the important software couldn't be rewritten/recompiled. I'll take any progress at this point.

Since there already exists multicore hardware, and correct me if I am wrong, multitasking especially when doing processor intensive things should be somewhat improved with an SMP kernel.
