Paperboy CPU Board Works?

Original Atari System 2 Paperboy CPU circuit board that we believe may be working. This board is one of the last one's from our "stash" of System 2 boards that we accumulated over the past 20 years.  It is tagged as working, but we don't have a way of retesting it at this point.

Boards sold as-is, we do suspect it is working, but are selling it as-is. See photos for more details on their exact condition.
