[Coco] I think now I have a final design

Hi Luis,

I read on your page you need 8 steps for the 3-Bit ADC. Is that worst case 
and if the value is low it will be found earlier? Just out of curiousity: 
Why don't you use the successive linear approximation as e.g. being used 
for the CoCo 6-Bit ADC? E.g. reading the CoCo joystick needs always 6 
steps instead of 64 worst case if just incrementing the comparison voltage 
from 0 to 5 in 64 steps.

Regards,
Torsten
