I have heard that some 64Kb limitations (for code or data) apply to the 68000. I
don't understand why, as it has 32 bits registers. The 16 bits address bus is
very similar to the 386sx 16 address bus (the 386sx had 32 bits registers).
What's the problem with the 68000? Are there really such limitations?
