typically when PC Quilter is being sold with the laptop its because its one of the first issues of PC Quilter and does not work with any of today's more modern computers.
i would double check what version of PC Quilter is for sale and then you can determine if its worth the price and how much it would cost you to update if thats what you want to do.
i had a chance to buy PC Quilter with the laptop and by the time i determined the value of the laptop ($25) and the cost to update PC Quilter to the current version (over $1000) it wasn't worth buying in my book.
