92-character variant

eg, P/N 7363830

IBM-made 82-key typewriter-style keyboard for the IBM 5253 Display Station and 5254 Dual Display Station (both terminals for the IBM 5520 Administrative System). They were intended for facilitating document creation and editing, and management of their storage. They could also support an IBM 3270 emulation mode. This variant is the 92-character keyboard with an ANSI-like 2.25-unit left shift key and a "BAE" (large backwards-L) style return key. They had a 32Ω, 0.2W speaker inside though its purpose is presently unclear. The keyboard itself and its layout became the basis of the slightly later IBM Displaywriter Keyboard.
