Well, something is definitely wrong.  I can step through the boot process
and at one point I see one A.  Then I see "A A". Then it goes blank.  Then
it starts all over again.

I have taken out the BASIC ROS, the ROS controller, the IO cable driver and
one of the memory cards and this still occurs.  Taking anything else out
results in garbage or a blank screen.

Thought this would be relevant. Also, thanks for the transcription.  I was
going to type it in myself.
