Success!!!!

As you all may recall, I have had a problem with the memory boards since 
the beginning of the project.  I put Dan to work extracting information 
from his father (Merl) and as he told me how things worked, I was able to 
understand the problem.  I will write up a Service Note to describe the fix.

All along I was blaming software.  Well, I put every hardware fix in place 
that I could think of, so it had to be software.  ;^)   Now that I 
understand the problem, I don't know whether to call it a hardware problem 
or a software problem.

The key is that I did not understand the programming sequence required to 
set bits in the Memory card register.  So the Memory card was not being 
properly reset.   Once I performed the right sequence, it worked the first 
time.

This is a real load off my mind.  I must admit that I despaired building 
any more systems beyond RICH since I was not sure that I could get memory 
boards to work.   Now I am confident that I can get as many Memory boards 
working as I need.

The only reason that any Memory boards have worked in the past is that they 
happen to come up with control flip flops set in the right condition.
