Oli's ColdFire Board

[bloodline]

Hi Oli, I was looking over the A1200 CPU slot and noticed that it Has Left and Right Audio signals on it... A quick hunt around some technical documents shows that any signals piped into these pins will be mixed with the Native Amiga Audio and squerted out of the Audio RCA's at the back of the Amiga.

If you include a sound chip on the board (I seem to remember you saing somthing to that effect), then could you pump the Audio output via those pins and make one really cool Amiga accelerator and soundcard in one!!!! :-)

Just as long as you keep the sound chips audio isolated on another output for people who want to use it for music apps. Paula isn't exactly noisless when the channels are open - I can hear the effects of system activity through mine quite often when using Sound Studio. Its faint but it finds its way into recordings easily enough...

I'm always facinated how "blitter noise" seems to make it's way through the audio output of "integrated audio" solutions... The weird thing is that the noise is present even if the volume is turned down to 0... which leads me to think that if I could get some decent grounding I could reduce the noise too.

coldfire vs amigaOne?
what makes the coldfire solution better than going for AmigaOne? is there going to be a complete amiga clone motherboard using coldfire cpu onboard?

Nothing makes the Coldfire better than the A1, but the Coldfire is more fun and will allow aging hardware to get a bit closer to modern specs in terms of CPU performance.

ColdFire sounds cool to me. If it sees the light of day and I have the money by then, i will probably go for it. At the same time I can't help but think that if the Amiga PPC platform does become truly viable, the ColdFire will be little more than a curiosity... then again, that's kind of cool too :-)

With all due respect (which really goes without saying), do you not think that the Amiga/AmigaONE/AmigaPPC/AmigaAnything is nothing more than a curiosity now anyway... :-/

Thus a coldfire makes a curiosity, an Ubercuriosity :-D

Like I said, if it becomes viable :-) I'm aware of how incredibly unlikely that is however...

Uhh!! Yes, point taken. I should drink lees beer and get more sleep before I read your posts :-)
