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. I’m using the right jumper configs to provide 12v to the 6581s. All measurements suggested in the build guide were double checked and everything seems normal. Is there anything im missing? Why the real sid chips wouldnt work if the swinsids are? Again, both 6581 Sids function perfectl
I'm having some weird LED issues on a sammichFM I just built. Both rows of LEDs light up or flicker when I pass my finger near the pins linking the display board to the mainboard, over the traces, or over the 74HC595 shift register that runs the LEDs. The LCD, buttons, and encoder all operate properly. Any idea what might be the cause?
