has connection to the parrallel port from the website pic. Does it
support unipolar motors ? where are the connections for the
motors ? $125 is a good deal for 4 axis.

The 4 axis driver board can be connected to any step and direction
control lines. It is designed to work with the DeskCNC controller,
which is physically similar to an external breakout board for a
parallel port.

The driver board has header pins for the step and direction control
lines. A single matching, pigtailed connector is included.

The motors are connected to terminal connectors. 4 wire only, with
this type of driver chip.
