The data bus is 8 bits long.  The address bus is 24 bits long; during
the first half of a cycle the high order 8 bits of address show up on the 
data bus, where they are externally latched so that they'll be around for
the second half of the memory cycle, which is where most of the action takes
place.  There's no way you could have 16 bit data bus expansion slots, I
don't know what they do with the addressing of these slots now.
