00000001
00000011
00000010
00000110
00000100
00001100
00001000
00001001

I used a shift register that I loaded with 00000111 then tapped off even
second bit to drive the stepper, ie b0, b2, b4, b6.  I could then rotate the
shift register  in either direction and drive the stepper in either
direction.  Not what you want but its how I generated the pattern.
