Found that old opl2 chip, YM3812, from Yamaha, basically part of an old 8bit sound blaster card.
Now I'm wondering should I leave the chip on board or should i try to hook it directly on a Mega256?
I found the PDF with the pin out:http://pdf1.alldatasheet.com/datasheet-pdf/view/84281/YAMAHA/YM3812.html
Sound reasonably doable eider way but I would like a second opinion on this before starting the party.
Basically the card is MCA format, the Before ISA bus. And this bus is also well documented. I found some library for the chip, probably will need to be adjusted for the Arduino world.
But yeap What would you do leave it on board or stick it to a bread board?
