Thanks everyone for the info. I live in the States and have never tried to buy anything direct from Europe, it's probably expensive. I will look around the usual vendors first.

There used to be site with a download (schematics, foil patterns, and software) or maybe I got it off Aminet, anyway, I found the archive on my HD. If you can't find it, I'll E-mail it to you. I'm tempted to simply put one together too, but, I haven't found a source for the MAS3507 chip. I wonder how many people have built their own. It would be really cool to incorporate an audio mixer into the project so the output of Paula, a CD drive, and the Mas Player could sent to single set of speakers. Or, maybe all sounds from the Amiga are routed by software through the Mas Player already. Is this true, anyone?
