Help!!! 

A friend of mine is running psychology experiments on the Mac Plus.  Currently
he is using the interupt counter to time subject responses.  With this approach
he can measure time to a resolution of 1/60 of a second.  Unfortunately he
needs a more precise measure -- like 1/1000 of a second resolution.

I think the Macintosh Plus is capable of doing this by using the disk and
sound driver timer but I haven't a clue how to do it in Light Speed Pascal.

Any -->'s appreciated!
