How would one acquire an old version of Maple (say 8, or 9)? Is it something that is easy to do? Thanks. edit... Maybe I should add that I have Maple 7, but one of the classes I am taking next semester will have a book that has programs that need some of the things from Maple 8+ (I guess they changed a few things around), and I would prefer not to spend $100 upgrading. Are there easy ways to get around this?
