Well, I for one don't have any reference that shows that the original prop had any of these chips inside of them, and I doubt they did. These may have been created specifically for the Rodenberry.com prop replica, and were drawing from TNG's isolinear chips as design inspiration. I like their inclusion into the prop replica, so I'm mirroring that here to add some cool functionality to an otherwise limited screen-used prop.It's easy to see where TNG got their ideas for the isolinear chips from
