Problem
1. Describe the 68000s BERR* exception sequence. Explain why the 68000's BERR* sequence is limited by comparison with the 68010 and later 68XXX family processors?
2. What is a double bus fault and why is it described as fatal?
3. The 68000 has a user and a supervisor mode. When the 68000 is in the user mode, it is impossible to execute privileged instructions. If you were a systems hacker how would you attempt to get around this restriction? If you were a systems designer, what would you do to attempt to make your system hacker-proof?
