Playing with Arduino and YM2149

Today, I played with my Arduino to connect a Yamaha YM2149 ( know too as AY-3-8910. After some times I finally got it to work !

And contrary to all other works I saw, I didn’t use an external Quartz, the 2Mhz clock I used is generated by the AVR chip.

Here some pictures :

I will post more informations/code/vids later after porting a YM player.
