More about this type of keyboard...
The IBM Space Saver Numeric Keypad is the complimentary numeric keypad option available for pairing with Model M4 and M4-1 keyboards. It's largely the same design as the IBM Personal System/2's L40SX numeric keypad option, however, the case is enlarged to match the design of the host M4/M4-1 and an extra "00" key is added at the expense of reducing the "0/Ins" key to a single key-unit size. Without modification, these keypads can only be used when coupled to an M4 or M4-1 host keyboard via a modular 10P10C ("RJ-50"-like) cable.
