Compare Maxima and Macsyma



 Hello
 
 I want to work with Maxima now. I know that Maxima is based on DOE Macsyma in 1982. And I consider two questions:
 
 1) What is the differences between Maxima and Macsyma ?
 
 2)What is any advantage of Maxima comparing to Macsyma?
 
 If anybody know any document about that or if you have any experience can share, please let me know. Thanks a lot.
