Icesid is an open source FPGA reimplementation of the famous MOS 6581/8580 SID chip used in the Commodore 64.

The icesid design has been primarly written to run on the reDIP-SID board designed by daglem. That means it can be used directly as a drop-in replacement for the SID chip in a C64.

Special thanks go to daglem for both his SID wisdom and generosity in sending me an reDIP-SID board to develop with. To Sylvain "tnt" Munaut for his patience answering lots of my questions and his invaluable work to get the reDIP-SID up and running. Also to Paul Sajna for helping develop aspects of the code and extensive testing.

Drop by the 1BitSquared discord if you have any questions about icesid.
