I've worked on some coin op stuff as well but more video game oriented. The original software ran on Windows, I did a linux port to show that 'it could be done' without windows. The hardest part was to switch from one game to another (multi game console) without a video mode reset.

Another application for that board is on-board computer for cars. I've got a very similar board in a nice little case that just fits under the passenger seat and wires into the car by running cables to the side of the transmission tunnel. Boot times are short (runs off a flash disk) and media are stored on a small 2.5" hard drive. I like these little systems.
