I have an Ultim809 PCB up and running and I've written my first graphical game for it, a nearly complete implementation of Asteroids (in assembly language, of course!) If you're around, come see me at the Bay Area Maker Faire on May 21-22, 2011! Yes, I spent a good amount of time looking at spectrographs of the original Asteroids sound effects so I could accurately reproduce them. I'm especially fond of the extra life sound, it brings back memories :)
