There is no such thing as abandonware.
That is a good, though touchy point. I've seen both sides of the argument and can understand why either party feels the way they do. Technically someone, somewhere still owns the copyright, patents, intellectual property, etc for the program and should be compensated for it. However, if a company does not have a method to receive that compensation either through a web site, mail order catalog, phone number, or messenger pigeon then it certainly should be an option for a person to acquire it by whatever third party means they wish.
Of course, I am getting a bit off topics. Sorry. :steps off soapbox:
