Ever used Virtual PC on a Macintosh? This is a program
which allows you to install Windows on a Macintosh and pretend that you are
using a Wintel setup. I understand that you can actually install Windows XP
directly on Mac OS these days, but a couple years ago Virtual PC was one of the
ways you did it.
Anyway, the point is that it allows you to adapt the
adaptee’s interface (Mac Hardware’s interface) to the adaptee (the Wintel
interface). You can install Windows XP programs as if you are working with a
Wintel, so you are actually exposing the Wintel interface publicly (the target).
