Museum of the Game® & International Arcade Museum® Forums

I recently got a super off road and got it working other than the sound.

I've adjusted both pots, installed a new power supply, and haved checked the wiring to the speakers.

I read that zero sound could be the 80186 but I'm finding conflicting information on the speed of the chip. The one currently in my game is 80186-1 but I can't find a replacement that matches it.

Any advice or suggestions would be appreciated. Thank you!
