87-key typewriter-style EBCDIC keyboard for the 3270-family IBM 3178 Model C4 Display Station. It was a part of the continuation of IBM 3270 Base Keyboards that originated in the IBM Model B keyboard family era, specifically implementing the RPQ 8K0932 327X-87 type Model B Base Keyboard's layout originally for IBM 3276, 3278 and 3279 Display Stations. This layout was notable for its 12-key combination adding machine style numeric keypad with 12 program-function legends. It has an internal solenoid clicker assembly and a blue-coloured display case toggle switch. It was only available in US English.
