They can address the full 32bit address space (without banking) and the
z380 adds a host of addressing modes not in the z80 like 32bit indirect,
PC relative and stack relative with long pointers. Also MUL, DIV and a
handfull of other nice instructions that would sharply speed on the math
functions. Also there are 4 sets of registers compared to the dual set
of the z80/z180.
