The original offices for the Electrical Controls Group was in a building on the old Donnelley complex near McCormick Place. We got to watch McCormick Place West go up from our windows. Later we moved to a new office building in Lisle.
We all had cubicles and shared a few PC’s. The programming of our equipment was done with “luggable” computers, large steel behemoths that we wheeled around the plant on carts.
