8086 Microcode Browser - Small things retro

Since releasing 486Tang, I’ve been working on recreating the 8086 with a design that stays as faithful as possible to the original chip. That exploration naturally led me deep into the original 8086 microcode — extracted and disassembled by Andrew Jenner in 2020. Like all microcoded CPUs, the 8086 hides a lot of subtle behavior below the assembly layer. While studying it I kept extensive notes, and those eventually evolved into something more useful: an interactive browser for the entire 8086 microcode ROM.
