Hello, Thanks a lot Soclt and ultra for your offers, but I ordered and received a Midisport 2x2. Now that I got a little time, I've been able to test it and it works much better, I've been able to program the PIC with MIOSStudio :) Now I'm stuck with stupid problems : - I don't have a jack plug, so I had to solder some headphones for now. - I used connectors everywhere on the core and sid, I've tested and I've the right voltages everywhere... then I plugged every components on the SID PCB and... the J2 connector doesn't fit anymore because of the SID chip. Guess I'll have to cut this connector and solder everything directly but I don't have time right now. That's just bad something like that happen right near the end. Olivier ;)
