I looked at 1983 games and their were endgame and tactical errors (if ofcourse they weren't opening book mistakes) Beyond games played in 1983 and upto Deep Thought-Kasparov 1989 this is a bit more difficult to say. I tried finding the mistakes but saw that it is beyond 11ply. I will continue to look at the games with and without the computer as you would be suprised by just looking at the move that you can spot ugly mistakes and even if it isn't obvious subtle errors pop up.
