As to your question, how people did it before silicon, I suppose they used log tables, which would be terribly tedious I expect, from what I remember of using log tables. Possibly, some people might have tried slide rules, though I question the obtainable accuracy. Of course, that being said, what do I know.
As to tabular methods, wasn't H.O. 211 one of the first such methods in this country? I believe H.O. 214 came into use on the late 1930's, while H.O. 229 dates from the 1970's, correct me if I'm wrong. There are or were other methods too.
