Hello,

I have a soundblaster ct2940 but unfortunately without the OPL3 and the associated YAMAHA YAC516 chips.
I have sourced separately the OPL3 YMF289 and the YAC516 chips and would like to solder them on the board (I'm quite experienced and skilled in that field). However the areas around the chips are not populated and I cannot find any datasheet or info about the capacitors and resistors values. I don't want to risk destroying retro hardware by randomly soldering stuff on that card.
If any of you have any info about it that would be great!

Thanks!
