To support the different types of address pins, four different circuits were required, more than I'd expect. The 8086 is full of special cases: The top 4 address pins also provide status, but one pin constantly updates while the others don't. The bottom 4 pins use an extra latch.

@kenshirriff I understand Intel used to HATE adding extra pins to DIPs. Today's processors have more than 3k pins ... vorsprung durch technik! |
