New sound card for APPLE II

I'm researching for new sound card.

 

 

And I got good progress now.

Please have a good time to listen old game music. ^^;

 

 

 

 

 

 

It is prototype SD Music card for APPLE II computer.

This sound card compatible with Mocking board but not 100% compatible yet.

Anyway, I will keep doing to make it better.

Thank you
