John,
It has been said before that the Pilot, Sample, Prototype, Engineering Sample - It was not exactly consistent terminology. As for that it means in what we are selling, it is what the boxes items have documented. Some of these are complete and accurate to the catalog. Some are truly samples missing components and not ready to run. We list everything we can easily see or we know, but these are NOT to be assumed as catalog correct and complete, just as the auction description states.
For any item you are not sure about, please feel free to email us a question and we'll answer as best we are able. Thanks!
Jared
