  12. Hi again..
  13.  
  14. Just wondering how I would build a circuit to let my read 8 bits on the
  15. parallel ports..  I have heard of people doing hardware that allows
  16. them to do two reads of 4 bits to get the full byte.  Is that a
  17. multiplexer?
  18.  
  19. How would I build such a circuit?
  20.  
  21. Thanks again for the help in advance...
  22.
