That'll work. Getting 5v may be difficult (joystick port is one good choice).
Another way would be to hook an opto-coupler (peanuts at a radio slack
or similar) between a parallel port data pin and parallel port ground.
Hook the opto-isolated trigger pins to the winder trigger. No
external voltage required.
Then output a 1 to that pin to fire the winder.
(If you don't have a winder, there are still Ways).

Yup, that's the way. Of course, True Believers run Unix. :-)

Yep.
