AmigaOS 4 developer interview: Why it endures and what the future holds

To the surprise of many, the Amiga operating system endures, with developers continuing to eye new features for the venerable OS. We caught up with AmigaOS 4's lead developer to talk about the system's survival.



The future

Solie says the AmigaOS team is happy to borrow ideas from other operating systems. "For example, the memory subsystem borrowed the idea of slab allocation for memory management. The integration of Python into the operating system was also a borrowed idea."

Other operating systems can also learn from AmigaOS, he says. Primarily, "keep things simple and respond when the user clicks on something. One reason I keep returning to AmigaOS is because it is relatively simple.

"As more features are added it is difficult to keep things simple and efficient, but so far so good."

Solie can envisage a future where AmigaOS 4 shifted away from PowerPC to another platform. "However, there is also a lot of life left in PowerPC," he says, and switching hardware platforms is no guarantee of success for the system.

"I think a successful system is a combination of functionality, applications, operating system and supporting hardware all for an acceptable cost. If your target market is the hobbyist market then perhaps PPC isn't as bad as people think. It really depends on the fans and what they will accept."


One gap he identifies in AmigaOS as it is now is good support for printing. PostScript printers are fine — but otherwise "you are in for a world of hurt". A system like CUPS, which made printing on Linux systems a less daunting prospect, would be great, he says.

Hyperion is currently working on AmigaOS 4.1 Update 5 is in the works now. "AmigaOS 4.2 will come later on which will introduce hardware accelerated 3D support, a vastly improved file system API and many other features," Solie says. The list of features that Solie would like to see added is "endless". A modern file system is one feature, and multi-core support, which is currently being worked on, is another.

"I don't imagine AmigaOS will ever become mainstream again," he says. "It is not that I am being defeatist. I'm just trying to be realistic. There are dozens of operating systems out there that are not mainstream and never will be.


"There isn’t a huge amount of new hardware coming out to run AmigaOS but it is a steady flow. Keep your eye on ACube and A-EON because I don’t think they are stopping any time soon.

"So for me at least, as long as AmigaOS remains fun to use I will continue to use it. It is a nice break from the grind of business where Unix and Windows rule."

As to whether an AmigaOS 5.0 will ever be released, "it all depends on the fans."

Only Amiga Makes It Possible !



Very nice read. Keep up with the good work.

I use AmigaOS. The system is fast and responsive.
"Remember when computing was fun?



What a load of BS. A-EON hardly shipped immediately, they announced the product would be ready by Summer 2010 and then it was a year and a half late. It was even a year late for people who preordered!

OS4 itself is almost ten years out the gate but is still in beta. Buggy, slow, crashy, just go read the forums at OS4 doesn't even support USB2 yet nor does it have 3D drivers.

The flagship X1000 was originaly pitched as being a game changer because it has an XMOS chip on board and also a proprietary slot connected, but despite having been in development now for over two years OS4 doesn't support these features. OS4 also doesn't even support the typical onboard hardware such as audio, graphics, and networking. Instead the user must purchase PCI cards supported by OS4 to offload these functions. Not to mention that this X1000 system costs over $3000 USD and is slower than a $300 PC you can pick just about anywhere.

Don't even get started on the total lack of software! Virtually ALL of it is Linux ports. There is really only one choice when it comes to a web browser, OWS. The OS4 dev team tried to port FireFox but that effort (called Timberwolf) so far has fallen rather flat, resulting in a crashy and slow application that after three years is barely out of the alpha phase. Remember FireFox 4? You will when you use Timberwolf because that's what it's based on.

You want Amiga? Look up AROS, MorphOS, and UAE. AROS is an open source AmigaOS workalike which can run natively on your PC or under Linux. MorphOS is a commercial effort which also runs on PPC systems and unlike OS4 has solid developer support in the form of actual software, not empty promises. UAE is the venerable Amiga emulator which can run on a regular PC, Mac, etc. Any and all of these options have better support and reliability than OS4, and will cost you thousands less to stand up.

Nice and honest interview thanks for that.

In other words, jim is a MorphOS fanboy.


Because he invested in a pegasos back then.
MorphOS isn't AmigaOS and isn't any better then AmigaOS, AROS and MorphOS has even less developers and the claim thats it more reliable than AmigaOS makes you look as retarded as a hipster Apple fanboy, why is it more reliable ? because it is according to you or just because it so happens that you don't have AmigaOS ?
Oh, UAE ? come on....

If you don't like Amiga, then you just could say it like this, "I prefer MorphOS over AmigaOS however" instead going AVGN/Adolf Hitler all over it.

Michael Schauber


AROS and MorphOS are the more advanced Amiga systems in the market. OS4 offers nothing more than a glorified UAE clone.



>Buggy, slow, crashy, just go read the forums at

Mine is not too crashy. A little slow on 667Mhz without L2 on heavy crunch, but super fast on things like disk I/O.

> OS4 doesn't even support USB2

It does.

>yet nor does it have 3D drivers.

It does. But not full open GL yet and not for r700 and newer radeon cards.

> XMOS chip on board and also a proprietary slot connected, but despite having been in development now for over two years OS4 doesn't support these features.

It does. Even though only first developer versions of support SW is out.

>OS4 also doesn't even support the typical onboard hardware such as audio, graphics, and networking.

It does. But not on x1000 yet.

>Don't even get started on the total lack of software! Virtually ALL of it is Linux ports.

Not true. Even though more original SW is wanted.

>The OS4 dev team tried to port FireFox but that effort (called Timberwolf) so far has fallen rather flat, ...

I use Timberwolf only to access my network NAS GUI as it's the only browser on any AmigalikeOS that works with Lacie NAS dashboard (I have tried also with MOS and AROS).

What is needed next for AOS4:
- more SW
- more drivers
- cheaper 1GHz+ HW



More info on AmigaOS 4
More info on AROS
More info MorphOS

It would be nice if some commenters on anything amiga threads would be more civil.



Ehhh People complain but they not use the actually system they complain about..
My A1k X1000 is Fast, robust and very funny with AmigaOS4.1 u5.

not like people describe before, buggy slow etc.

what is wrong with some people today??? too little pussy or what?



AmigaOS4 is quite stable on my Sam440, it's even very fast considering the hardware

Sure AmigaOS lacks a proper memory protection cause its original structure (only some internal parts are protected under AmigaOS4) but the same problems afflict other Amiga like system aswell ..

The same problem about software (not so mutch) but as hobby system is quite usable and funny to use



I have a problem with me!
Difficult to get OS4 compatible computer!
I use the machine is still classic 68K!
Computer games, general word processing, graphics, video edit, e-mail, etc.
Works well for a long time.
PowerPC to be that well-run modern applications.



AROS is UAE emulator clone written by Janus, and is rally slow in real hardware and WinUAE, how is that for trolling :-p, get a life people, we go around drag etch other down…



BME kill amiga dreams



AmigaOS it is historically Amiga operating system. MorphOS and AROS are just only clones. Both of these systems were created to help Amiga but after more than 10 years of development brought only community split. Amiga has no chance without cooperation all sides of community. People responsible for creation projects like AROS and MorphOS are egoists. They want to be part of Amiga world but they don't help Amiga at all. There is no sense create two Amiga-like systems with all disadvantages of genuine AmigaOS. Instead of one good AmigaOS all of these developers give us three outdated operating systems from previous century. Community should send to hell all of these developers. Well organized community should speak about one modern AmigaOS, not two clones and one system created in spare time. Amiga today is obsolete and Amiga community today is obsolete. There no future for Amiga, is it?



Nice to see AmigaOS/Amiga getting some publicity, Hyperion AEON and ACube and many developers and fans are keeping the Amiga alive ,and thats a very good thing :)



Ordered me an Amiga os4 machine (Sam 460) after reading this. i dont care if the amiga is old school, i like computing because it's fun, and so, i like alternative os.Looking forward to post from my sam next time!;)

Mike Brantley


Thanks for the well-written and informative interview with Mr. Sollie. I'm a longtime fan of Amiga computers but mostly the Amiga operating system, and I'm thrilled that the latter, at least, is still alive and under development. I get great enjoyment and productivity from creative applications from both modern times and the classic era with my two AmigaOS4 computers based on ACube's Sam440 motherboards. I'm very much looking forward to owning -- and will very soon -- the comparitive powerhouse that is the X1000 from A-Eon. Don't get me wrong; Mac OS X, Linux and even Windows7 get some of the daily grind ground up here. But my AOS machines are the computers I enjoy most. Keep this party rocking, folks.



Excellent review. Good to see the AmigaOS alive and kicking in 2012.

AmigaOS 4.1 update 5 is very fast, stable and more importantly is fun to use! :-)



Interesting! I ordered ten X1000 systems to my company today!



I'm following the AmigaOS's life since the early nineties (and i learned about its former life). I owned one A1200 with an MTec 030 accelerator board and it was good even for my Computer Engineering univ studies at the time. In 2000 I have put the A1200 to the shelf.
As a SW engineer, having architected some SW systems, i like the Amiga OS concept, which was designed by Car S, AFAIK. It has very good responsibility assignment of the core components and the definition of types of those components (libraries, devices, resources, etc ...). Though, the messaging system could have been designed better - with creation of Msg boxes which could evolve to be protected now.
But - all in all It has foundation that still can be built upon, IMHO.

So why i do not own one next gen Amiga when I'm so found of the technology ?
A: No solid basis. The Sam460 which has a good price/perf ratio (to amiga land) lacks some drivers, so i won't consider it till they are ready. I just wonder that noone from the dev team considers that ?! Should be prio nr.1, IMHO. Remember the fat microsoft guy screaming "developers, developers, developers,.." on video ? You won't get a mass of developers till you provide them a complete product, especially for that price.

Other than that, it looks sufficient to me for development. Has a browser and usable SDK - from what i heard.



I really liked the Amiga a lot and stuck with it way beyond the Commodore breakdown until 1998. But now there are at least two very good Windows alternatives available (Linux, Mac OS X) and that's why I don't see myself working on an Amiga ever again.

Thanks for the details.




You can't argue with believers.

And it is true.
OS4 is a blame of all things, you known as an Amiga. It is wrong fundamentally. Morphos (hell, yeah), and AROS is the way.
And they're not clones, they are the only way out for Amiga to the future. :)
I own some Morphos and OS4.x machine. I use them daily basis. Morphos is far more usable, than os4.x. Period.

- a true blue troll :) - made by Hyperion, and teh rael Amigaaa(h) (C)(R)(TM) way of the computing. :)



Great interview, explains a lot, thanks Steven!
AmigaOS 4 is not e.g. up to Linux but is way ahead OS 3.9, and it should improve more



I still find the basic structure of Amiga OS superior to the major operating systems out there. Windows with its stupid registry and the way it handles disks and devices, and Linux tied to gather with huge numbers of scripts, with layer upon layer of complexities. With the success of Android, I've never understood why such a simple, logical system, and of such a very small footprint, like Amiga OS, wouldn't be ideal in today's computing market. I guess it would take someone with vision and some cash to make it happen.

"..Instead of one good AmigaOS all of these developers give us three outdated operating systems from previous century..." One could replace "AmigaOS" with *nix but who says this about Unix, BSDs & GNU/Linuces, despite much older origins than Amiga OS?

In both cases efforts have been wasted re-doing things, but the ability for developers to fork off free software projects & do their own thing also reduces the waste of conflict.

Personally, I believe the feeble hands of various claimants of intellectual property rights have kept all Amiga like systems out of the mainstream. They could have had a smaller piece of much bigger pies if they had not always prioritized legal action.

And Amiga OS should have been on smaller platforms before such hardware was able to run Microsoft or *nix OSs. An Amiga desktop is a niche in what's becoming a backwater.

Vojin Vidanovic


Interview is very OK and shows many ups and downs on a rocky road. Its not always Hyperions fault on delays, since they didnt fund the development until end of court case and couldn`t make decisions alone and Amiga Inc hold very littke interest to OS4 until their AmigaDE failed to materialize.
MorphOS is way more optimized because is longer in development, AROS is cross platform like Linux and OS4 is catchimg up fast, that is I will say. I use AROS on PC, OS4 on SAM and am getting PowerBook to run MorphOS

@Howard: "With the success of Android, I've never understood why such a simple, logical system, and of such a very small footprint, like Amiga OS, wouldn't be ideal in today's computing market". Just three motivations: lack of SMP, lack of protected memory, lack of common development tools, libraries and middleware like Java and mono/.net. I love AmigaOS simplicity (which is REAL simplicity, not the one that hides complexity with a nicer GUI) and I miss it on current mainstream operating systems, but the only place where I see some industrial application for amigoid systems is the embedded market, where a small footprint OS with well-written applications (that won't crash just because one has written in the wrong memory space) can deal with low powered configurations. Take the Raspberry Pi, for instance.



"Take the Raspberry Pi, for instance. "
Oh no, not again.



Actually there was as defacto protected mode. I don't recall offhand the package name (my copies of the AmigaFora libraries are in storage) but if you had a 68030/040 equipped Amiga it implemented virtual memory, complete with protection, by patching the hell out of the interrupt vector table. Message passing was patched to do copies instead but there wasn't much, if any, speed hit due to the faster memory. You also had protection on the cheap by using Enforcer and MungWall but it really didn't help much besides letting you know how/why some program crashed due to memory violations. I used to have those both running 24/7 as it was another test I made aside from virus-checking on uploaded software for the Amiga Fora.

Talk about some ancient history ;-). Perhaps I'll take a look at rejoining the community.
