I would not toss them, you can make some money selling old software. The $500 for DOS must be a joke to be honest, there are other shrinkwrap copies of the same thing going for little on ebay. I think somebody found a case of them and made a fake auction to able to sell the other copies for a good price.



P.S. If you find old copies of Ultima series in box (PC DOS, Amiga, Atari ST, etc with the cloth maps and metal trinkets) they seem to always sell for a few bucks on ebay (not even shrinwrapped).
