I added the color DMD chip. It was expensive at $399 for a simple CHIP, but I think it is an significant improvement. The graphics are way better and I think I'm also hearing some call outs that I hadn't heard before. I had to make some adjustments in the playfield brightness cause all of a sudden it was too dark.
But it's all good now. Interestingly the DMD itself is actually a lot LARGER than the backbox cover of the Classic Edition makes visible. I wondered if anybody had figured out a way to make use of the additional display real estate like the SE & LE do?
