Found a Mars:God of War at the local antique mall a few days ago.Guy had it as non-working,as-is for 200 bucks.Offered 150 today and brought it home.At the store I could hear it boot but no displays lighting up.We brought it home and it musta liked the ride cause now the displays work.Game coins up and starts but no scoring,flippers ,etc.Sound works but it's like a Mars Rap... can...can...can...cancancancan...you survive??? Goes on forever...LOL.Playfield is quite nice...inner backglass is a homemade thing out of plexi that isn't too bad...cab is good too.Time to do some digging.I'll post pics later on...
 
Found a connector I left unplugged...then was able to play one game.No scoring,no sounds except the annoying mars rap.More digging...
 
mars god of war, very nice, i have 2 of them i like it so much hehe, had to buy 2nd one just to get back glass. heehh
very cool game love it.

im not 100% sure on how to fix that kinda of sound issues.

i will say that the driver board tells the sound board to do things in a simple manner, play sound 1 is ground line 1, 2, 3, 4, etc. and then 1&2 at once for another sound.
i dont see how a failure in the driver or cpu could make it do that rap....

maybe cpu issues?
