Question: 1. The quoted physical address space of the 68000 is 16 Mbytes (i.e., 2 24 bytes). I could maintain that it is 64 Mbytes. What is the argument I might use, and am I right?
2. What are the relative merits of the asynchronous memory access and the synchronous memory access?
3. Can the 68000 be operated in a synchronous mode by strapping its DTACK* input to AS*? If it is possible to do this, what advantages and disadvantages would this mode of operation have?
