I purchased an SP985 chip from another member here and installed it today. I was able to get to 2-0 by pressing the self test switch behind the on/off toggle switch on the right side of the machine. When I got to 2-0 I turned the JP reset key until I got to 58, I was able to press the spin reels button and it went 1-10 on the settings, so I set it to 5 and closed the door and played a game, but the sounds are at the same volume they have always been, probably loudness of 2 or 3 in my opinion. Is there something else I may be missing or could try?
Thanks,
David
