ARMSID is a plug-and-play replacement for the MOS 6581 and 8580 SID sound chip used in the Commodore C64 and C128.

Simply remove the original SID and insert ARMSID into the socket — no modifications required.

It delivers accurate sound, significantly lower noise, and much less power-supply interference than the original chip. The 6581/8580 mode is detected automatically, but you can switch between them at any time using a simple C64/C128 configuration utility. The utility also allows you to fine-tune the audio filters and test your ARMSID.

ARMSID has lower power consumption than the original SID and the firmware can be easily updated directly from a C64/C128 application.
