Well.... no. But it's true that cheap hardware like the Beagleboard and then the Pi benefitted existing RISC OS users who were struggling along with old hardware, and most likely brought back a few ex-users. The Beagleboard particularly was the fastest RISC OS machine at the time, and was only £100, so proved quite popular.

OS4 on a cheap board like the Pi would do the same. However for it to be cheap it would need to sell loads, so either it has to have some other purpose (breaking into Pi's market with a PPC-based version likely isn't a viable option though), or OS4 would need to be ported to such cheap hardware (porting OS4 to ARM, whilst likely to be much easier than the port to PPC given the previous work that has been done, is still going to be expensive and slow, and you'd need to add a Petunia-PPC emulator or lose all the existing native OS4 software)

There's no quick, easy, cheap route here.

The Raspberry Pi 3b+ is a quad core 1.4 Ghz machine. Even the 1.2Ghz was playing 1080p video running Kodi.

Who needs hardware like that for $35 when you can buy an X1000 for thousands?

In any project money needs to be considered, maybe this is the main repeated error done in Amiga market by many companies, they didn't focused well on the end user costs.
Now that also powerful hardware has become really cheap, and can be totally virtualized, the most important thing is software.
I don't want spent more than 300/500 euro for a limited/experimental Amiga computer.
I would pay instead until 60/70 euro, with a smile well printed on my face, for an Amiga OS4.x running over a RaspBerry, or similar cheap hardware, for an overall optimal price between 100/300 euro.
A lot of old Amiga users will try such combination and maybe with some killer apps and/or some killer hw expansions modules, amiga market could reborn with new users.

Is there any proprietary firmware etc. in the RPi that would require fees to use or license to develop for commercially?

If broadcom updates/changes their chips will all development tools be supplied free?

Probably more questions along the same lines.

Preferably would buy a two thousand Power again than a 15 quid motherboard You can stick in the pc. If You have a cp why bother even that? Get an Atari.

Seriouslu that could be an idea. Not in these hands. (XE works)

But there is this always. Give it a Nasa Military Class but what to run on it?

IBrowse 1 for a start.

If Hyperion doesn't have the resources to finish the drivers for the Tabor in a timely fashion, I don't think a port to a new architecture is very likely.

But I do agree that the Pi, or some other ARMv8 platform, would make a good architecture for an Amiga-like system.

Porting should be easy-ish.

Here's one ARM port of UBOOT ;)
https://github.com/fail0verflow/switch-u-boot

Then it would just be the HAL...but again the Raspberry Pi documentation is widely available...

I don't like to say what others should do but IMHO if they want try to survive it's a must to port OS4 to much spreaded and cheaper hardware, sell many thousand copies, became independent from "hw companies" and live with their own forces (and money) as pure software house.

At this time it's very simple to say but very hard to do, I know..

That is a spot-on comment.

Hyperion does not do drivers.

They do write drivers,

The drivers for AmigaONE-XE/SE/Micro.
AEON also write drivers, and ACube-Systems write drivers.

No matter who writes drivers, it slow process, it hard because you need to reboot the system every time you write bug, system lockups are common while you write drivers…

So write some lines of code, reboot to try it… then crash… then reboot into working system, annualize logs, find bug, and write few new lines, reboot boot, and watch system crash again.

Writing the catweasel Mk4 driver for AmigaOS4 was really frustrating period for me.
(Only a fraction of the code in the Linux drivers was usable to me)

Luckily, for me "catweasel Mk4 driver" is not a required component to boot AmigaOS
Personally, I was happy to see Ian take over the project.

With programs, you just kill program, and fix bug run the program again, you can't really do the same with drivers messing with hardware, and you can't unload a crashed .device in safe way.

Also Pi firmware is on SD card, so it's highly likely U-Boot isn't even needed - you could just stick the Kickstart files on the SD card and boot directly.

It's still a lot of work to port even if it is "easy-ish".

RPi3 is a quad core ARMv8. Has anyone tried single thread operation on it?

I think RISC OS is probably a single thread OS.

RISC OS runs in 32-bit Arm7 compatibility mode using a single core on the RPi. Probably similar to what a port of Amiga OS would. I have started RISC OS on the RPi, tried a bit web browsing and as long as it was not too complicated sites, it worked fine. It was nice with 1080p and I liked the window system. I have not done much with it so far, I may go back and try more at some point.

Now my RPi is doing service as a proper aarch64 box running openSUSE. Emacs, Git, Haskell and various window managers just works. I configured the XFCE window manager I use to be polite (avoid focus theft) and not to bring the window with focus to front, if I do not tell it to. Browsing can be done with care. These browsers tend to consume all available memory (1GB) with just a few tabs open.

A short question... who will finance the port of AmigaOS? And do not say Trevor D., he is heavily involved in PPC hardware, he would financially shoot himself in his own legs when he would support the transition to a different and cheaper ISA
