Me too, except there seems to be a slight error in his example code.  If you
exit the NybbleOut routine with the last DATA bit as a '1', it won't clear
the shift register on the next go-around, but instead load it with '1's.
You have to clear the DATA latch first before you run through that section
of the NybbleOut routine.

Of course, if it works with '1's, then why clear it at all and waste 31
instruction cycles to "clear" it?
