	Sorry it took so long to reply to this.... the host I was using
as my news machine has been down the last couple of days.  

	I think your prof is going a bit overboard on needing accuracy
of +/- 1 uS, especially for a phych experiment.  If you *really* need the
accuracy, then the best thing to do is to build a small counter circuit
which can be read by the Amiga (say, through the parallel port).  IT's
relitively easy to build the circuit to reset a timer, count , and stop
the timer according to some external trigger.  The Amiga (or whatever), 
at it's leisure.

	I don't think using an Amiga to do the actual timing is appropriate.
Apart from the obvious waste of computing resources, the Amiga is geared
more to timesharing then realtime jobs.
