Sorry, but this is not a satisfactory explanation. Microsoft managed to create a DOS virtual machine that can run programs that try to manipulate memory directly by simply providing virtualizations of the actual hardware so the DOS program thinks it's writing to real memory. I don't see why that was not possible for Apple to have done the same thing, unless, of course, it's a matter of the Motorola chips simply not supporting that kind of virtual memory architecture.
The Universal Turing Machine can emulate any other Turing machine and the von Neumann Machine (to which real computers are an approximation) is equivalent to a Universal Turing Machine. Any modern processor, combined with sufficient memory, could provided a virtual DOS environment. The only question is whether it would be fast enough to be useful.
