> However, even using extra hardware wasn't enough in this case. So they pre-calculated lookup tables for sine, cosine, tangent etc. for every angle at the necessary precision.

Is this really the order of events? I imagine the pre-calculated route is what you'd try first, and only go for extra hardware if that failed somehow.

Lookup tables were commonplace in 80s-90s graphics programming. It should have been used before any consideration of custom hardware solutions.
