I purchased my arcade machine at an auction, and when I was taking it apart, and cleaning it, one of the things that I noticed was a white "cardboard" cover on the marquee.
It actually goes on the inside of the machine, behind the light. It basically stops the light from bleeding to the back of the machine, and focuses it all out through the marquee.
Unfrotunetly, I can't find it anymore!!
Anyone know what it's called and where I can find / buy it??
