This is cool, but the renormalization and (Programmable and bidirectional) barrel shifter are of much more interest.

I had a 10Mhz XT, and ran a 8087-8 at a bit higher clock rate. I used it both for Lotus 1-2-3 and Turbo Pascal-87. It made Turbo Pascal significantly faster.

You're in luck, I wrote about the 8087's shifter back in 2020 :-) https://www.righto.com/2020/05/die-analysis-of-8087-math-cop...
