[Jukebox-list] Question #3 and final: One Million BC Midway E/M arcade

[Dan Gillitzer]

I know this is off topic, but hey I could be posting about the Iowa caucus I guess.
Friend with the AMI model C also has a 1968ish Midway 1 million BC E/M shooter game, has early electronic sound, and pretty sure the board (or chip) is no good, every sound is just a loud "thump" noise from the speaker. Anyone know a source for part to fix,or someone who restores these??
