IBM 5251/5252 Display Station Data Entry Keyboard
Provided by the ASK Keyboard Directory
525X-66 type Model B
IBM-made 66-key (most) or 69-key (Katakana) data entry keyboard for the IBM 5251 Display Station and 5252 Dual Display Station, the inaugural terminals of the IBM 5250 family for IBM's midrange computers. The keyboard is a lot less common than its 83-key typewriter counterpart and uses a layout similar to IBM Card Punch keyboards. They had an internal solenoid clicker assembly and a cut-out above the keys to hold a template for writing down the names of functions assigned to various keys. They had a short, grey cable terminating in a female DB-25 plug.
