Unfortunately, I have to be away from UO this first week. I will be back
next Monday. Professor Strom will meet with you for the first class.
I will be reachable by email after Wednesday if you have
any special concerns \\
({\tt rayfrey@cosmic.uoregon.edu}). As indicated in
the printout of the initial course web page \\
({\tt http://zebu.uoregon.edu/$\sim$rayfrey/433/433W00\_info.html}),
we will cover two major topics this term. For the first topic
we will build a 68008-based microcomputer using the
material from the {\underline{Student Manual for the Art of Electronics}}
by Hayes and Horowitz (``Hayes''). This book is {\em required} this term, 
as it will be
our primary reference for the first part of the course. 

In the second part of the
course we will do register-based programming of PCs to control
external instrumentation via A/D, D/A, digital control channels, and
counters/timers. Your project will be controlled by a PC in this way.
More about this later.

In the meantime, here are some assignments to get you started:

\begin{itemize}
\item Labs. The lab sections begin next week. We will do Lab 15 of
Hayes: Sections 15-1 through 15-6. We will go over this lab in class
on Tuesday April 4 before you begin.
The circuit you build will be part
of your microcomputer. So build the circuit on one of the small (unpowered)
prototype boards to be set aside and saved for use the next several weeks.
We will use the commercial keypad circuits mentioned by Hayes. These will 
have to be shared. But that is easy, since they have convenient connectors which
are readily plugged/unplugged from your prototype boards.

\item Reading. 
\subitem $\circ$
Read Hayes Class 15 through Lab 16 (pages 342-402). (The material starting
with Class 16 can be put off until next week.)
This is review material. But the context leading toward the microprocessor
labs is useful. The reading should go quickly. 
\subitem $\circ$ Horowitz and Hill, Sections 8.25 and 8.29.

\item Homework. Due Thursday April 6. This should not be new material. 
Three problems:
\subitem $1.$ Using D-type flip-flops, design a synchronous decade counter
which counts from 0 to 9 in binary.
\subitem $2.$ Horowitz and Hill, 8.35
\subitem $3.$ Horowitz and Hill, 8.36. Be sure to include a timing diagram
to analyze this.

\end{itemize}
