I know that the micro were weaker than deep thought but the question was about
comparison of the micro with other opponents except cray
blitz(Hitech,Lachex,Waycool,Socrates).

I know for example that Socrates lost against Fritz3(p90) in 1995 in a game to
decide about the world champion.

It's hardware was better than Fritz but I do not know if it was better and I
remember that it lost because of a tactical mistake.

Socrates was probably better than other players in the list like Lachex and
Waycool.
