The object is a metal panel apparently designed to bolt to a larger object. On the front of the panel are 16 red indicator lights (all are populated) and 16 white indicator lights (all are populated). A plate attached to the front of the panel reads CS RESET. Etched on the front of the panel are INDICATOR PANEL MOD II and M.I.T. DIGITAL COMPUTER LAB. On the back of the object are 2 terminal strips. Attached to the terminal strips is a board containing integrated circuits; these attachments obviously postdate the original object. A label attached to the unit reads "Whirlwind Stack 6J."
