Cyclone
Williams, 1988Friend has an issue with a cyclone with a new rottendog system 11b voices. Plays music files fine. But none of the voice samples play in game or in test. They worked fine when the old board worked. Never worked once rottendog board was installed. Music is fine. Sound test isnt.
I have seen people had problems where sound was loud and distorted with rottendog boards
I'd check the cables between the MPU and the sound board. Music and voices are generated by different boards on Earthshaker . Mine was missing all voices, replaced MPU with Rottendog and now it works.
Any diagnostic bongs happening from the sound board? https://www.pinwiki.com/wiki/index.php?title=Williams_System_9_-_11#Boot_Up_Diagnostic_Tones_for_the_D-11297.2C_D-11298.2C_and_D-11581_Sound_Boards
Quoted from DK:Check the PIA chips. I’ve had this issue before on a Pinbot with the same board
Hmmm. . . .Rotten dog has the daughter board that does the voices, I would make sure everything is connected well including the audio "mixing cable" from the daughter board. If that is not connected there would be no voices.
is the daughter board nest on top of the MPU board? what does that look like? I wonder if that is missing?
i'll double check this aspect of it. does it connect board to board or is it all connectors. because all connectors have been reset about 10 times, and wiggled around. But if it nests into the other board like a sandwich with a solid connector, that might be a thing.
I thought the daughter board was only for 11_ and 11A games. Cyclone is a 11B game.
Can you get some pictures of the MPU and sound board connected?
Rottendog has two different implementations of the System 11 CPU board.
Williams implemented different parts of the entire sound package in different places.
^^^^^ This is his board ^^^^^^^^^^
he also says the sound chips that say speech on them, are on the sound board that is off on it's own. They both say music/speech.
How about swapping the short ribbon cable around so the red wire is on the left on both boards? Try to rule out the ribbon cable as a suspect.
Time to replace that Rottendog with a new board we know would be tested before it shipped.

I think I would.swap the Hitachi 6821 that is in U109 of the sound section with the one in U38 of the switch matrix. I can't tell which brand is in U38, but if the speech works then you may have the switch matrix not work. So problem should follow.
can't swap boards because we don't have another one. Rottendog is known to have these sound issues with system 11b. Guess it followed to this version of board too.
Actually, I thought the speech issue was only when the daughter board was used with 11 and 11A games.
Just can just be a bad PIA, which is why I suggested swapping U109 with U38 on the same Rottendog board.
All in all, I was suggesting to sell back the Rottendog and buy one of the Dumbass boards, which we know get tested before shippimg.
I have no faith in the Rottendog board, especially now that the original guy manufactured the board has retired. Any Rottendog boards found these days are either until untested or have issues. It will be rare to find a working board. Sell it on Ebay or Pinside.
Buy the board from @dumbass, as we know he has very good support and stands behind his tested boards.
Has to be the Rottendog having issues. As previously said, the speech call outs are generally generated from the main mpu. My whirlwind had the tiniest amount of acid on 2 SCRs directly above the battery holder and every once In a while would go through a crazed cycle of saying “well lookie here bye crackle! Whirlwind!” In a distorted voice repeatedly once it started until the game was shut down. Replaced those and cleaned entire area and it’s worked perfect since. With WW also being 11B I’m betting the Rottendog MPU is the issue.
DumbAss I echo all the thanks you’ve earned with your work on these machines. I’m hopeful I can get on your list for a Cyclone board! Thanks again!
After some research I finally have most of my first gen mpu9211 boards fixed. Various post pointed to adding a 10k resister to the aux sound board for reducing unbearable sound volume. The board was basically unusable new out of the box. The newer gen boards have a 2nd sound pot added below c112 on the mpu. I tried adding 10k to c112 and it works great. I also tried lower values but this was the winner. As others have stated, the single sound pot seems irrelevant since no difference in adjustment. However some said it needs to be turned bunches. I hooked a small flathead bit in my drill and went to town. I finally made a difference. This allowed me to balance out the sound. You may be missing half of your sounds like me because of one volume way to loud and the other way low. After 2 Years I’m ready to put this baby to good use. Now on to finding out the display is out on another nib 9211.
