Author here with another 8087 article. What part of the 8087 should I look at next?

Minor erratum: "1.1 (binary) × 2^8 is 304" should be 384.

Thanks! I guess I didn't have my glasses on when I read that number :-)

righto.com has been great reading. None of my friends wanted to pay for an 8087, but I can still remember getting out of school (for 2nd time) and saving up for the 486DX after 3 others got them. After that, well, it's been quite a ride.

Have you already covered how the decoding of instructions is shared with the 8086?
