Some 'perspective".  In 1973 chess 4.0 was searching under 1,000 noded per
second.  The fastest it ever searched was 2,600 nps running on a cyber176 in
1976.

I don't think _any_ program of today would lose to any program of the 1970's
as the hardware advantage of today's machines is simply far too great.
