Thousands of these were sold as bare boards with limited doc's. I frequently
ran into folks using them, yet never saw one in the original Xerox enclosure.
The Xerox box was just too expensive. Once they were no longer a major product,
they were surplussed out as bare boards. I think it was through BG Micro.
