Have a dead SID chip in your Commodore 64 or 128?
Replace it with a SwinSid Nano chip and get the sound the machine deserves.
This is not a perfect solution but for the price is a great way to get things working again.
Simply remove the old broken SID from its socket and replace with the SwinSid.
There are solder jumpers on the board to select between 6581 and 8580 chip types.
