ColdFusion CF4000 prototype Arrives!
« on: July 11, 2006, 11:08:42 AM »
The prototype CF4000 that was to be shown at the AmiRevival has arrived!




This card is a CPU upgrade that lets the Amiga (3/4000d/T) use the V4 Coldfire made by Freescale. (Motorola)
The V4 Coldfire is available in speeds up to 220Mhz and has a build in SD-Ram controller supporting up to 512Mb of PC100 memory.

I have uploaded some pictures:
The whole board, showing the CPU pads, SD-Ram and Fastslot connectors and debug connectors.
The all important sexy photo. (And the real reason for the gold plate... My name is in gold!)
And a nice close up of the CPU area to finish up.

The card will be assembled in the next two weeks and then the job of testing it begins. :-)

This is the third ColdFusion prototype since the project was started way back in 2002, the last prototype was shown at the Benelux Amiga show.

Well, be careful this one doesn't go up in a puff of smoke aswell... ;-)

I would suggest everyone to hold their horses for now. This is far from finished product.

Well done!

Dare I say the ColdFusion might beat the vapourware Dragon to market? :-)

Well the Dragon is for the A1200 so technicaly their not competing products ;-)

Good to see more classic development!

Ok, the board looks nice (although I preferred the blue colour of the 2003 prototype).  But the hardware is the easy part.  The difficulty is in getting AmigaOS and Amiga apps to run on Coldfire (the same thing which is causing Elbox's Dragon so many delays).

I thought this project had been abandoned. Nice to see it's still going!

@ Lando: it looks plenty blue from where I'm sitting.

I remain dubious, not about Oli's ability to get this out to market,; but about the ability of Amiga software to run on it. There've been many discussion threads about Amga Coldfire cards which generally give the impression that it'd effectively have to emulate a proper 68k chip to run a large amount of software.

Why does a 68k cpu has to emulate a 68k cpu?? I have read that this is required for some fpu instructions only. Like when a 040/060 tries to run old software that uses the 688882.

Coldfire is not 68k CPU.

That's not the case.

Anyway, check out the thread about Elbox Dragon compatibility?, it has some discussion about the coldfire emulation issues. As you can see there isn't exactly full consensus about this matter, but as soon as (or if ever) some coldfire accelerator hits the market we will know for sure.
