Dave was one of my favorite people in my group.=C2=A0 He was the first pers= on
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.=C2=A0 It had a ribbon cable the length o= f 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<= br> how far a key was pressed down.
