Here's a great website I found last week while putting together a "history of FIRST" presentation for our rookie classes

This gives the field layout, description of the games and scoring, and a general description of robot limits for that year.
There are a couple of threads that have discussed this before where Al and Andy have given a similar description of earlier years as well. I'll edit this when I find them again - I just did a CD search for "previous year game" or something like that.
Here's the thread:
