I fink Alan Turing showed that provided you had a big enough digital computer,
enough time, etc, you could simulate just about anything on it.

You'll have to excuse me if that's wrong - long time, bad memory, etc.

Yup... most NN work is done by simulation on digital computer (I believe).
The point is that what takes a digital computer a night to simulate can be
done in milliseconds by a NN.

There are NN chips becoming available now - can't point you at em, cos this is
all way outside me area of expertise.

Oh... and analogue computers is still in use, although rarely encountered.
One use is is seizmic work, I believe.

Danny (still way out of any area he knows anything about - so no 
       flames please :)
