Good grief. That is not the point. The machinery is largely irrelevant. We are talking function and use.
Scenarios are examples. They are like mirrors of the world. The image alters depending on what you are looking at.
Auntie Dora might have been given a 120MB Pentium with colour printer. But if all she cares about is "cookies" and "strudel" and printing in black and white,then she might as well be using an XT. If the BIOS overflows to 1980, Auntie Dora could not care less. She is still Class 0. Does not need or use dates.
