Weekly update

I have ered lined most of the RAM board.  I just need to check the power and
ground planes.

I wrote up a summary of where we are on the CCU/TCU definition.  We have
agreed on a power fail support strategy (flush the cache).  The definition
should be completed this month.

I built a tester measure the speed of a 25ns Cypress static RAM.  I have
compared driving there test jig (lumped RC) to driving a PC board (transmission
line with small C on the end).  I am not sure what the best way to drive the
array is.

I an scheduled to go to Cypress on May 2.  I sent them a list of questions that
I would like answered so that they could have answers ready when I got there.
This should only take half the day and so I should be able to spend half the
day with Cheetah people to discuss there needs.
