Quoted from woodmedic:I think the sound is very poor which is why I found a system 11 MPU to put in it. I just hope the board I found will work without too much trouble.
I have a spare System 11 (nothing) board that I ran a bench test on. You definitely need to follow wayout440's advice about connecting certain pins to ground.
