IBM-made 50-key bank teller keyboard for IBM 4704 Model 1, 2 and 3 Display Terminals, components of the IBM 4700 Finance Communication System. This keyboard layout is divided into 3 matrix sections that were originally facilitating 45 customisable (relegendable) keys and 5 fixed-function keys. The keyboard was envisioned to allow basic data entry, account management and transaction management. 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.
