It's somewhat easy to see the field delineations on the die, using 's beautiful die images of the NMOS 80286 that, unfortunately, revealed an unreadable implant ROM.

Fields can be ascertained by the way the ROM outputs run off in groups.

Here we can see the first microcode fields are 6, 6 and 6 bits.

omg mark of the beast.
