The 3B+ was 1.4Ghz, this one is 1.5 ... seems like a nice bump in IPC...

OS4 port to PPC took 3 years until public pre-release (with many parts still 68k and running under slow interpretive emulation). Our community (I mean developers, not mere users) was much stronger back then (2004). There is no manpower and resources to undertake this effort once again.


Sorry, but that's a clear testament to the people behind the effort and not the effort itself.

The lack of available technical resources is also pure bunk. Other more arcane technologies have evolved and flourished.

What you are correct about is 2004 being a pinnacle year in the decimation of the Amiga.

Re: AmigaOS on Raspberry

By absolutely NO means I'm claiming to be an expert.

But I would guess... ok, maybe hope it's the more appropriate word (!!!) that with a solid foundation already in place (for example I believe it's safe to assume OS4 already having a HAL should help a lot) a potential ARM port with proper funding and the right people working on it should be doable in a far shorter timeframe than the 3.x --> 4 effort.

HAL or no HAL, just look how long it takes to port AmigaOS from one PPC system to the next and you got your answer.

Tabor was shown for public November 2015 and it's still waiting for Hyperion to finish their work. Now ask yourself how long it would take them to do a port for whole new architecture.

I assume problem are both funding and finding right people today

That's why I added "with proper funding and the right people working on it" to my not-so-educated guess.

I think "soon" we will no need to have a porting on a arm.... in 2026 (the tabor release date) the arm will emulate ppc code in interpretative mode fast than the tabor one cpu.

That's arguably terrific and somewhat saddening at the same time...

My thinking is, between AmigaOS 4, MorphOS, and AROS, whoever get up and running on the RPi4 first wins.


Win what? Inexpensive hardware options are already available for AROS and MorphOS and the user bases are similarly as small as that for OS4.

Only used stuff, some of it fairly obscure. I have never succeeded in getting AROS to run on *any* hardware that I own. It runs fine hosted on Linux, but I would like to try it native, which at the present time is a very hit-and-miss proposition. AROS would be more popular if it had a cheap reference system that is readily available and *new*.

Small bump when moving from an in order 2 wide "LITTLE" core to an out of order 3 wide "big" core.

@Kronos

Or look at all the hardware MorphOS exists for and how much faster MorphOS shows up on new hardware. Why would OS4 be different? Maybe because it is not "done right" and maybe because there's hardly anyone left to do anything at all. Because yay Hyperion.

I have succeeded in getting AROS running on my A3000, so I switched to it.

Otherwise this is a major problem. I do not want to source second hand components from ebay that I do not even know how well it will work together.

@Rose

You are under the illusion that Hyperion are doing any work? They are not, the company has noone with that kind of skill, the best they can hope for is people willing to do all work for free for them, under an NDA. Such people are long and far between, typically they chose to use their spare time more wisely.

Read my posts again. I'm most definetly not under any illusion that they could pull Raspberry Pi 4 port before it's availability ends 2026. They have burned so many bridges that even without NDA it would be hard to find right people to work on it.

performances look like near or better than the udroid xu 4 . it mean the pi 4 is faster or equal to the x5000/40 in computing performances. i m really courious when i will have it.

A HAL helps but Drivers would be the big hang up
