I am writing a program in THINK Pascal in which I would like
to time the user's response.  The tic stuff in Pascal is too slow.
I would like msec or faster resolution and tic is for 1/60th of 
a second.  The absolute units of time isn't critical either.
I am trying to time the interval from presentation of a picture
on the screen until the user presses the mouse button.  I already
have the button press part, I just need a timer.

If anybody has some code to do this I would appreciate it.  Please
e-mail me and name your price :^$.

I actually want to time the interval from the presentation of a picture
to the voice response of the user.  I am thinking of attaching a voice
activated relay to the mouse button input which is just a grounding of
two pins.  If anybody knows of a better way to do this please let me know.
Is there a better port for this?  Is there an inexpensive input card that
would do this better?
