I just did that to my Sinbad last week. I have done this to all my system 1 games that have chimes. I will take some pictures tonight when I get home. I typically add a connector so I can easily switch between the chimes and the sound card. I like the chimes but they are loud and makes for playing at night hard without waking up the neighbors and the rest of the house. The chimes also have a hard time keeping up when you have 3x, 4x and 5x bonus.
