hi all,

please take a look at following points

1. it has separate internal/external data and code memory so that it satisfies the first condition.

2. its look like it has the external common data/instruction bus, one can make a point that for sake of multiplexing intel did that, you can use either instruction bus or data bus no matter what wires you are using. PSEN is provided to switch between the two. in other words separate pins are not there but buses Logically exixst. is there any flaw in this?.
