I agree, the "Module Pulled" message and adjacent E#'s in the titles confirm the seller removed the wand and then immediately took photos for the listings. I also agree the custom overlay must be for an external HP-IL device (maybe connected via RS-232 interface) as it includes a "DIAG" command. Possibly this was used in some manufacturing scenario. It is amusing that they bothered to label the "g" key with a "g".
