Quoted from knobstone:Hi Everyone,
Just picked up IJ over the weekend, and had a question about a secondary board attached to the DMD board in the backbox. Here is a picture of the board. I have never seen this board on a machine, and it's not mentioned in the manual. Also, I have installed a ColorDMD display, so I don't even think I need this.IMG_1381.JPG Thanks!IMG_0922.JPG
Looks like an after-market bypass board for the high voltage section of the WPC DMD controller board. If you're running with the ColorDMD, you can remove that board.
