I've only taken part in the installation of one controller, and I found it...interesting. The controller itself is pretty much one board, which is awesome as far as fewer pieces to break goes. But when the board goes, you can't just swap it, you've got to get a new one.

I did a two stop traction, and the access and fire keys were all networked to the controller with CAT-5, which was kind of cool.

I didn't care for the prints though. Why deviate from the norm? It makes no sense.
