Well, I just wired up a cable, plugged it all in and it looks like I probably crossed a line. All I get is a line of solid blocks across the bottom. Centrafuse _is_ trying to write to the display, you can see it clear and then the blocks come back.
I'm out of time to mess with it this morning, and I'm gone for the weekend, but I'll be back Sunday night.
More when I know more!
