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

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.
