Subject: Re: iAudio M5 / X5 ?

Re: iAudio M5 / X5 ?

So I bought the M5 and just came back from my vacation. Hoping for some
hacking soon! :-)

I also noticed that someone on the forum already opened up his M5.
Great, that means I can postpone voiding the warranty for just a few
weeks more! ;-)

Hmmm. I got it to open, but don't know yet how to move those parts from
the disasm'er.

Can you send me the IDC as a start? :-)

Hopefully DataRescue will add it soon then. So it's not possible to
write plugins that are based on existing CPUs somehow? A shame... :-(

Where's that page? Can't find it, could be interesting/useful.

I added some links to the ColdFire wiki-page BTW, including a link to
an introduction to m68k assembly. Might be interesting for people like
me, who are only really familiar with x86 so far.
