Hi
 It depends. Not all parallel ports are created equal.
Many are bi-directional though. There are about 3 different
flavors. As I recall, I connected the parallel data out
to the data lines and ran the strobe to one of the status
input lines. There is a start and stop signal that uses
to start and stop the tape as well. I can give you a copy
of my code.
 There is a web page, http://www.lvr.com/parport.htm , that
has several links to parallel port stuff. Since you are now
at the hardware level and on a roll, this is a good place
to look.
 I don't recall if the two drives that you loaned me were
parallel or serial outs. I think one was a parallel though.
