Dave was one of my favorite people in my group. He was the first person that met who was absolutely brilliant in technology but couldn't spare any cycles for things like tying his shoes. Another interesting thing that he designed was the keyboard that eventually got hooked up to the music playing version of the digital filter setup that Hal Alles and Jim Kaiser designed. It had a ribbon cable the length of the keyboard that was fed by a binary pattern, and each key had an antenna that moved across the cable when it was pressed making it possible to determine how far a key was pressed down.
