I'm hoping to use the IBM PC or XT to run experiments which will
require gathering reaction times to stimuli presented on the screen.
The response to the stimuli would be the pressing of one of two keys.
I need the timing to be accurate to a millisecond.  Does anyone have
experience with doing such things?  Can anyone recommend a good clock?
Also, can anyone recommend a good consulting firm for getting such
things working?
