Message-ID: <20080319160259.B9BC945006A@zimbra.ece.msstate.edu> As mentioned in class today, I would like to "re-do" the first lab meeting from last week. I have a seminar tomorrow from 2:00 till 3:00, but am available at 3:00 to do the lab meeting. Also, as mentioned, I do NOT think it will take a full three hours, particularly since we have already gone through some of the presentation, and you have seen some of the hardware material, too. Now that I think about it, I would anticipate that you should be able to complete it in about two hours. So, with all of this in mind, please respond as soon as you can as to whether or not you are available to do the lab meeting tomorrow from 3:00 till about 5:00. (Thursday, March 20, that is.)
