The machine looks beautiful and you've done a wonderful job
I always liked playing Wild Fyre when i was young ,thought it was a great game.
With your sound board ,the SB100 with the least amount of parts is the newest version of it , they must have realised they didn't need half the parts to make the simple tones.....so it sounds like the soundboard you have in it now is the early version of it ,probably came out of a Lectronamo
