Watching this 8-bit guy video, where he's using a Gameduino to provide video for his "dream computer", I began to wonder if it might be possible to connect the Gameduino to the M100 via the parallel port or the expansion bus? It wouldn't be a replacement for the internal display like a DVI would, but software could be written to use it, probably even to echo the internal display to it.
Assuming it's at all possible, to begin with. https://www.youtube.com/watch?v=ayh0qebfD2g
