sammichSID help : swinsid vs real 6581
Hello everyone!
Last year i’ve built a sammichSID, which was functioning and sounding perfectly with a pair of SwinSid Nanos. Recently I got 2 6581 from a real C64, and they work well in the C64 but when i use them in the Sammich, i get no sound at all, and sometimes i can hear a little noise.

Is there anything im missing? W
