The IBM 5253 Display Station and the dual screen 5254 are video terminals made for the IBM 5520 Administrative System, and were amalgamations of the 5251/5252 and the later 6580 Displaywriter System. The terminals, which looked identical to the 5251/5252, supported 3270 emulation and were designed to create, process and manage documents locally or remotely. The keyboards which were almost identical to the 6580 Displaywriter, had two known layout options: an 82 key, 92 character keyboard and an 84 key, 96 character keyboard (shown above). The major differences between the keyboards of the Displaywriter and the Administrative System were the color of the keys, and the legends, with the Displaywriter having white keys and the Administrative System having black keys and more specialized legends. Not very much is known about this system because it was it was a commercial failure and was withdrawn from marketing only three and a half years after the first order was shipped.<ref>https://www.ibm.com/ibm/history/exhibits/pc/pc_5.html</ref>
