Hi,

According to David Levy and Monty Newborn's book "How Computers Play Chess"
The program Chess 4.7 had a rating of 2000 elo and Chess 4.9 had a rating of
about 2100 elo. Unfortunately they do not give a rating for Chess 4.8 (in fact
that version of the program is not listed at all, was there such a version?).
I believe these elo ratings are US values.
