Mockingboard 4c is preparing

Dear Friends,

This is 2nd commercial version of Mockingboard 4c.

First version was sold out so, I needed to prepare more PCB for Mockingboard 4c.

I little adjust the sound input level and sound doesn't off to avoid OFF popping sound.

And CPU little relocated to upper for easy soldering for me.

Sound little improved and easier to solder by me.

I'm testing compatibility and works 100% as Mockingboard C.

Please wait some weeks for next batch of Mockingboard 4c.

Thank you

Ian Kim
