Need Help Stereo Mod on Genesis 1

Post by jungec »

I am thinking about adding RCA Plugs for Left and Right sound.

can I use pins 20 and 21 to get stereo sound or do i Need to look elsewhere?

Would i use pin 1 for the shielding on the rca jacks?

Below is the pinout for the sound chip.

name: YM2612
function: FM sound generator
package: DIP,24
manufacturer: Yamaha

Check to see if the traces to those pins go to the op amp that goes to the front jack.
