I have an HP branded dial box, an A4362A. It looks identical front and back to the photos of the SGI DLS80-1022 on Wikipedia. I have the stand for it, but seem to be missing the two brackets that screw on to the back of the case to hold the stand in place. https://en.wikipedia.org/wiki/Dial_box#/media/File:SGI_dialbox_DLS80-1022_front.jpg https://en.wikipedia.org/wiki/Dial_box#/media/File:SGI_dialbox_DLS80-1022_back.jpg
