   Dr. Patt,

   I just did problem 10 on the 3rd problem set, 
   and it's an absolute mess.  

   With a total of **** different states, and **** lines 
   going out from each state, I have a total of ****  lines
   going all over the place.  

   I guess that doesn't sound so bad, but on paper it's 
   a monstrosity.  Is it supposed to be simpler than this?

   <<as always, I must protect the guilty>>

Sounds good to me.

Yeah, I thought about dropping the cost of coke to 20 cents just for 
that reason, but my TA told me it was better to keep the price the same as what 
the IEEE students sell it for in the ENS building.  I think the real reason 
was my TA had already drawn the solution state diagram and did not want to 
redraw it.

You really think the picture is a monstrosity?

Good luck with the rest of it.

ps. I removed the actual values from his message, so as to not deprive 
you from the fun of solving it yourself.  I decided to share the message 
with you in case you solve it also, and are concerned that the state 
diagram is somewhat bigger than the one we developed in class on Wednesday.
