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.

There's a ton of coordination lately on P6 microcode. Would love to see what twists and turns there are supporting the older isa on newer architectures

I am curious about the transcendental instructions, how are they implemented, and used, and if actually used

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