Sorry I have been unresponsive to email the last two days.  I had agreed to
fly to Mexico late Wednesday to give a talk, and I just got back late this

First question to answer that is pressing on a lot of you: How far will
the exam cover?  Answer: all the material we have covered up to and
including all of Chapter 3.  So, the master-slave flipflop and danger
sign are fair game.  The instruction cycle (Fetch, Decode, ...) we will
save for the 2nd exam.

Good luck preparing for the midterm.  I will see some of you at the review
session on Sunday, and I will see all of you at the exam on Wednesday.
