Tried it, chased circuits, thought about building an interface, but never could get enough info on the scan rates and screen refresh circuitry (the differences). Someone built one once, remember reading about it...and thought, "why burn all that time? Just to be able to say, 'I did it!'??" I found a greyscale screen and just enjoyed 2.5 hr battery life. Amazing how long the battery will last w/o backlighting! Andrew
