Looking at the final 5 points of Rauber's chart, to emulate the computing environment would be VERY difficult and expensive. And it would also be mostly effort applied to something else than INFO, because most of the computing environment will not have been used to make INFO useful for human beings. What one wants, and what is readily feasible, is some computing environment that perpetuates useful rendering of the essential content of INFO. A Turing machine can be used to do that, and a Turing machine is much, much simpler than any widely offered HW and SW environment. See H.M. Gladney and R.A.
