This is another prime example of the ability to virtualize and/or
simulate a historical PC architecture. I used to write a lot of
software for CP/M 80 … and still have some of the hardware machines
in my basement. (Hmmm … note to self … consider selling on
eBay!)

If I were to want to run some of that software, I’d have to boot an old
PC … which means that I would have to have one around! Now I
can simply run the software on a “virtual” CP/M 80 machine.  I
truly believe that the world is going to move from trading pirated
software, to trading in pirated disk images.  You can provide a
disk image, and simply boot it with the right virtual machine …
