I have the specs on the SID Chip. I bought one years ago when everyone was putting a second one in the C64 to get stereo. I never put in the chip and can't even find it. but I do have the info. Would it be legal for me to put it on my web site for all to download? Mark -- Mark & Carlyn Grocholski MOZEPY Productions ><> http://home.earthlink.net/~mozepy
