Object is a hinged metal panel inside a larger metal enclosure. The panel bears two near-identical control panels, the upper one labeled "MSP" and the lower, "URP". Opening the panel reveals PCBs that carry a few small ICs (which dates the technology as at least the 1980s). The control panels a row illuminated push-buttons with legends like START, TROUBLE, ONLINE and Operator Interrupt. There are rows of small toggle switches labeled 0 to 15, and some small pilot lights and one male and one female round multi-pin connector. In general the panels appear to be for controlling some type of 16-bit computer.
