The FM OP2 Card produces the typical FM sound of the 80s with the YM3812 chip (Adlib/Soundblaster) which is backward compatible to the YM3526 (OPL1) used in sound cards for MSX computers. The card is compatible with the C64 SFX Sound Expander. So the usual FM software can be used for sound generation. 

 

The board is delivered completely soldered and assembled (incl. ICs).
