Micro SwinSID – PCB by Peter Sieg *updated*

October 11th, 2010 No comments

Micro SwinSID (SwinSID88) is a hardware replacement for legendary SID sound chip which was placed in every Commodore C64 computer.

This project is based on the microcontroller ATMEGA88PU from Atmel and the emulation code is written by Swinkels. The first version of the pcb (prototype) was made by Crisp.

On the left you can see the tiny PCB of the Micro SwinSID made by a user of the forum64.de.

*This PCB is compatible with Commodore 64 and 64C but you need to Remove the resistor R3 if you install the Micro SwinSID on Commodore 64/SX64 where the SID 6581 is used.

For more information and price visit the forum64.de.
