Absolute vapor.  Wouldn't trust the annoucement as far as I could throw the server it's hosted on.  There are apparently still significant problems getting the Coldfire to (properly) emulate the 68k instruction set (so I've heard).



Surely it's more flame-and-smoke than vapour ware?

OMFG, how lame was that?

*apologies*

It also seems to be compatible with A1200 only, for now. :-)

If it does come out, it would be a classic Amiga dream come true. It would also be bad for AmigaOne/OS4.0 sales, and would most definitely discourage some people from migrating to AmigaOne from the classics.


I dunno about that. Regardless of what they say, generic 680x0 code does not run on coldfire without some degree of modification / intervention. They would need a very effective (read Dynamo) style JIT to get 680x0 code running at full potential. A trap based emulation of missing instructions would be a poor affair.

Secondly, a 266MHz coldfire is unlikely to run coldfire compatible 680x0 code faster than OS4/Petunia on a G4.

If the card appears, and it works then it will definately be a 680x0 coder's dream, no doubt about that, but I don't expect it to compete in performance terms with G3/G4 PPC based solutions in real world tests.

Hey it just occured.

Someone is missing from this thread. If anybody knows tjaoz, I think they should check his place and make sure the milk bottles and newspapers aren't piling up...
