Figure out how to model crosstalk and establish a spec.  Look at the crosstalk
bread board.
T}:5:100:T{
I had some trouble making the test board match the models, but did get a fairly
good match in the end.  I am having a board cross sectioned to make sure that my
assumptions are correct.  The cross talk should be less than .1 volt.  We have
to be careful about other noise sources.  I pointed out to Richard Chou that
we get a doubling effect on the ground bounce.

Check the models and results for the SRAM outputs.  Decide what else needs to be
done.  Come up with a way to specify outputs for the SRAM's.
T}:6:100:T{
I did this plus I designed and built a circuit to test SRAM's with different
loads on the outputs.  I gave the VLSI people some preliminary specs to works
with.  I am close to coming up with a specification for the outputs.  I also
worked on SRAM pinouts.

Start the schematics for Gumby?.  This will for layout and also give me
