  Well, it acutally hooks up to the parallel port.  And the instructions
imply that the software has to initialize the hardware molded into the
specialized cable.  Have not gotten around to look at what goes in and 
out of this cable yet, since I no longer need to home-brew an ALDL interface.
The only reason I can think of for there to be hardware in the cable is
so that my 4.77 MHZ laptop can still read in 8192 baud data.  I imagine
a faster computer can just pole the parallel port and read in the data
that way.
