The object is a video terminal with a 10.375 by 5.375 display screen (note the widescreen aspect ratio). A door on the back flips up to reveal a "POWER UNIT" on the right side with an ON/OFF switch and receptacle for a detachable power cord. On the left side are the back edges of 10 PCBs. Four of the PCBs have edge connectors. One of the edge connectors is used to connect to a keyboard. Another edge connector is an asynchronous data communication port. There is a small rectangular opening in the grove on each side if the case. Inserting a small tool in the opening opens a latch. When both latches are open, the top of the case lifts to open.
