Help a late comer!

Dear everyone,
I have just joined this group.To be honest,I am still a will-be GRASS user.
I would like to know:
1.What platform do I need to run GRASS?How about SGI machine or small
SUNSPARC workstation?
2.I knew there is a FTP site where I can find source code of GRASS.But,is
there an established procedure to install,and compile the GRASS,such as which
files I should download with source code,where I can find step by step
instruction for installation and compilation?

I need your help to become a real GRASS user!
Thank for your attention!
