IBM-made 78-key operator console keyboard for the IBM System/370 Models 138 and 148 mainframe computers' 3138 and 3148 (respectively) Display Consoles. It was integrated into the large platform the console's CRT display was attached to. It's essentially a version of the IBM 3158 66-key Display Console Keyboard but with the added 12-key program function keypad. Unusually for an IBM operator console keyboard since 1972, it didn't have coloured "START" and "STOP" keys.
