Good job! That's pretty much the idea, my solution uses addition (here's
the 8086 version) and one fewer instruction (you could o the same by
changing the value on that
"SBI 0):
AND AL,0FH
ADD AL,0F6H
ADC AL,0AH
ADD AL,0F6H
ADC AL,0AH
ADD AL,0F6H
ADC AL,0AH
ADD AL,0F6H
ADC AL,0AH
ADD AL,0F6H
ADC AL,0AH
ADD AL,0F6H
ADC AL,0AH
ADD AL,0F6H
ADC AL,3AH
Next bit twiddler challenge--can anyone do this in fewer instructions?
Cheers,
Chuck
