>Ok, does anyone know where the SID chip is inside the C64? Look for a 20PIN dip close to the speaker plug (internal). Btw, 2wire digital sound is supposed to be possible...some guys are going to figure out how it works... I'm thinking about implimenting it on the EII... 4 sound chanels. 4bit? And its midi compatible. We could hook our calcs to kbds! Grant
