Object is a keyboard in a plastic box, mounted atop a metal box and connected to it by a data cable. The keyboard unit is like object 102730839 (has the same "equipment number" CA145A, for example) but has been mounted on a what appears to be a hand-crafted metal box. The data cable from the keyboard attaches to a DB-25 connector on the side of the box. The box has a CDC logo and a label "RESEARCH WIRELESS KEYBOARD DEMO" on the front, and a toggle switch with prominent labels OFF and ON. There is a row of four LED(?) pilot lights on the back panel of the box.
