</gallery>The IBM 5251 and 5252, part of the IBM 5250 Information Display System, are video terminals that were meant to be application configurable means of data entry, located away from, or directly attached to the host system. They could be attached to a variety of hosts, including: series /1, system/34 or system/38. IBM suggested using the terminals in areas such as a sales counter, an order entry department or a receiving department. The 5252 differed from the 5251 in that the 5252 shared a single display that was split with a mirror between two operators to create two screens, however both units shared the same keyboard offerings. They featured four different keyboards, a 83 key keyboard (standard), a 86 key keyboard (Katakana) a 66 key keyboard (data entry) and a 67 key keyboard (data entry with split spacebar). The 83 key keyboard shares its layout with the later Model F 83 key [[IBM System/23 Datamaster Keyboard|IBM System/23 Datamaster]], [[IBM Model F#IBM 5291 Keyboard|IBM 5291 terminal]] and [[IBM PC/XT Model F keyboard|IBM PC keyboards]] as well as the 5280 Distributed Data Station keyboards discussed below. The 66 key variant dropped the number pad and featured "data entry" key legends, shown above. The 67 key layout was nearly identical to the 66 key layout, but had a split spacebar with a 3 unit zero key on the right side. The Katakana variant had 3 extra keys to accommodate the expanded character set. Legends were offered in several different languages, including German and Japanese, shown above. The 5250 system offered a light pen accessory which allowed the user to select highlight and copy text by dragging the light pen across the screen.
