Those numbers were taken from the documents that I picked up from Atari employee who sold me all of his test equipment and service documents. The production numbers were contained in a folder of confidential documents.
When Atari finally closed down for good, I picked up the entire contents of their library. At that time another copy with some later 80's and early 90's production numbers was also found.
You can view the actual documents that the data was pulled from at
