SwinSID Nano
OverviewFPGA-based replacement for the 6581 or 8580 SID chip in Commodore 64 / 128 computers and compatible devices.
99% compatible with the original, with the exception of EXT audio input for samplers and analog inputs for paddles.
The SwinSID Nano has 2 configuration jumpers :
J1 : Filter choice. Open : New SID 8580 / Closed : Old SID 6581
J2 : To be closed when replacing original Old SID 6581. If the chip sounds too 'quiet', open the jumper.
