I just picked one up this week! Anyone happen to know what the two red buttons on the right side when you open the coin door are for? In figure 29 of the manual ( https://www.arcade-museum.com/manuals-videogames/I/icecoldbeer.pdf ) says they might be freeplay and ticket test button but not sure. Nothing happens when they are pushed and a freeplay button would be nice without modification. Also the one has a white wire not connected to anything that goes to the coin door
