Title: 502 504 s 2000 boards Post by: slotmani on February 07, 2014, 06:10:24 PM What is the difference between the 502 and 504 s2000 boards and if changed from one to the other would I have to do any other changes to the game to make it play?
Thanks lost and confused Dave Title: Re: 502 504 s 2000 boards Post by: Yoeddy1 on February 07, 2014, 07:38:37 PM 502 produces annoying static through the speakers. Do yourself a favor and make sure you get a 504B board.

Prob have to adjust sounds if you are using enhanced sound. Pretty easy process. Mike Title: Re: 502 504 s 2000 boards Post by: slotmani on February 08, 2014, 08:01:52 PM great THANKS

Title: Re: 502 504 s 2000 boards Post by: cowboygames on February 12, 2014, 03:03:16 AM There's no such thing as a 504 sound board. What you're looking for is a 504B MPU board. It's the only version of the 500 series boards that didn't produce static in the speakers when used in conjunction with an MMLII multimedia daughter board and sound simm. I even had a 504A that had static. Please note that when not using a multimedia board it is pretty rare to experience the static problem. When IGT put out a workaround to "fix" this issue it looked like a weak attempt at improving the grounding and didn't work well. You could expect to pay somewhere in the $50 neighborhood for a good 504B board
