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! -Dave Tcheng tcheng@uiuccsb
