Object is a single unit made by joining two similar metal boxes. The purpose or content of the box(es) cannot be determined from any external labeling. It might well be a disk drive unit. The top box front has a panel with indicators for AC, DC, BATTERY and I/O and REMOTE. There is a four-position key switch upper right (0, 1, 2, 3), and one red indicator light. the bottom box has the same panel but lacks the four-position switch and red indicator light. On the back there is a number of connectors of a variety of shapes.
