Forgot to mention, I have a 2382A that works (affectionately known as the "Munchkin" terminal). I could measure some stuff in mine for comparison if that could help out. For the HP curious, the 2382A makes an appearance at the end of one of my videos: https://youtu.be/GLkhcDAOVPo?t=19m50 It is very cute (I think) ;-) Marc
