So where did the PPC amiga thing come from?

[bloodline]

I would suggest it started back when the first PowerMacs appeared.

Hmmm, even then I think we were still very 68060 oriented... No one really took the PPC seriously as an Amiga CPU solution until Phase5 (who built Mac CPU cards) suggested it... And then did it

Competitive against what? Don't get me wrong, I like the PPC architecture but it's not competitive outside of a few niche (mostly embedded) markets. In the desktop market, there is no PPC processor that isn't totally smoked by an x86 part available less.

I would compound Karlos' comment, and say that I can't think of a single Market where I would choose a PPC over an ARM or an x86... Unless I was working with IBM who don't have a licence or the latest versions of those architectures

In 1995 AROS wasn't even close that could be called an Operating System. Back then AROS was a hack running on top of X.

Claiming that it would have been potential OS for some kind of x86 Amiga is worst kind of historical revisionism. AROS was years away even from AmigaOS 1.x kind of functionality. IIRC it took something like 4-5 years for AROS to actually boot on a x86 system natively.

IIRC, AROS something of a joke until Aaron Digula set out the initial goals after publishing his RFC in '97... Then Michal Shultz got x86 native booting sometime in '99, not long after I joined the project, but even then intuition didn't work properly and it was some months (in early 2000) before AROS would boot to intuition, with a nice mouse pointer (serial mice only at that time) and a window to play with...

Alas, bridgeboard cards weren't anything like the later PPC+68K cards so such a kernel could not have been developed. The x86 and x68K had their own physically (as in hardware) separate memory spaces for one thing...

-edit-

Kronos beat me to it.

What about Vortex's boards? These seem to have access to the Amiga address space

@bloodline
Being connected to the 68k-socket (or turbe-slot in the A2000) doesn't mean they have full access to the Amiga-addressspace.

Quite! But this particular board used system ram and I/O via the Amiga's I/O... So I'm guessing that the 286 must have more access to the Amiga than most
