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

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

      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.

      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 :-)
