Ram questions

[bob smith]

Hey Tony!
Good point that I forgot to mention, and from the posting with the 
original question, these seem to be ECC moduless and not ture parity!

  Duty, honor, country: Those three hallowed words reverently dictate 
what you ought to be, what you can be, what you will be. They are your 
rallying point to build courage when courage seems to fail, to regain 
faith when there seems to be little cause for faith, to create hope when 
hope becomes forlorn.
