This object has a metal frame with one open side, one side covered by four panels, and a door on the back. The thin panel on the far right has a red "Emergency" on/ off switch at the top. The front two thirds of the frame contain a roll-out unit with two hinged card cages. The cages are filled with IBM modules. At the top there is an orange add on bracket with one screw protruding from the middle. The back third of the frame is for cabling. In the right card cadge four rows of connectors have been replaced by a sheet of masonite and brackets holding power resistors. There is a small yeloow sticker above the door at the front reading, "Master Sync."
