Crisp created a PCB for the “DualCore SwinSIDâ€. The two AVRs are piggybacked to simplify the connections. Both AVRs are plugged into sockets, so that it’s still possible to flash a new firmware (Forum Article).

The extension board can be plugged into the SID socket of a C64 and MBHP_SID module.

Swinkels started to update his webpage.

There are new sound demos in the music section.. New schematics and firmware will be released very soon.
