The file
Two screens, one above the other, and a see-through green boxer so you could watch Glass Joe and Bald Bull wind up. The arcade original was about reading tells, and its stat-tracking top screen was pure 1984 tech.
The tune that later played in every NES kid's head was written for this cabinet by Koji Kondo before he wrote Mario's. The Tyson version is the famous one; the arcade is the better game.
