Thank you for this tremendous piece of silicon detective work. Really hope that that there are further instalments to come, for example covering the microcode.

Thank you for this tremendous piece of silicon detective work. Really hope that that there are further instalments to come, for example covering the microcode. Just to highlight too that footnote 1, describing the lengths that the Intel engineers had to go to ensure that interaction between the 8086 and the 8087 worked, is fascinating.
