Controlling spindle, coolant from Camtronics 2A board

Is there an kit or pre-made board out there I can hook up to the
Camtronics 2A board, or do I need to get a parallel port splitter and
have a seperate box to controll those two? Ideally I would like to
have spindle speed control (the spindle motor is DC, so I could use a
H-bridge chopper controller), but a simple ON-OFF would work too. I
mostly want to be able to have the spindle turn off automatically
after a long job.
