IBM-made 107-key typewriter-style keyboard for IBM 4704 Model 2 and 3 Display Terminals, components of the IBM 4700 Finance Communication System. This keyboard is the largest of all IBM 4704 keyboards and is essentially a further expanded version of the 62-key IBM 4704-200 Alphameric Keyboard and 77-key IBM 4704-300 Expanded Alphameric Keyboard with 45 and 30 extra keys respectively. All but two of the extra keys are relegendable keys for tailored alphabetic input or programmed functions - the remainder ("Attn" and "Clear") are predefined control keys. The keyboard was intended for administrative personnel. The keyboard's cover is made of zinc and has a volume-adjustable buzzer on the bottom intended to provide an audible alarm to the user on certain system and application program conditions.
