I'm with JohnI on this one. A nice small lcd display with graphics you can actually see what's going on with during gameplay is perfect in place of the DMD.. a huge screen is pretty much not necessary or beneficial for the player. That and a huge part of pinball at least for me is the amazing backglass art that comes along with it, big empty box or not

I think there's other video driving components on that board, the atmel just plays traffic cop for what to play. The HDMI connection isn't even populated on that AC DC board Likely only driving a certain pixel count on a dmd sized display. I like this platform as it looks very lean and purpose built with no OS to deal with, no full blown pc, lower power requirements. Just don't see a down side really.
