OK, let's
say I pull an old PC and some boxes out of a dumpster, and
there's a set of original AutoCAD Release 9 disks. By your rule, how
can I tell if I own a legit copy or not?
Real simple. It they're original disks then it's a legit copy! Doesn't
matter if it came from a dumpster or not.
Though some software manufactures would like you to officially transfer the
license to a new party. It's usually buried in the fine print of the
software agreement.
