This is a review of the LC3 from Patt & Patel's book. It
has to do mostly with programing in assembly and interrupt
and exception procesing. You can get much the same material
from trunk/docs/, in the PP appendices there and other
documents, such as the assembly language manual.
Also, review the class lecture notes on LC3.
