The '''IBM PS/2 Space Saving Keyboard''', sometimes known as the Model M Mini or the SSK, was an 84/85-key compact variation of the [[IBM Enhanced Keyboard]] produced between 1987 and 1999, and was available as an option on the PS/2, IBM Industrial computers and later high-end IBM systems. While the Space Saving Keyboard was usually available for the same price as the Enhanced Keyboard when bundled with an IBM system, it seems that most customers preferred the full size board, and thus the Space Saving Keyboard is less common. As with the Enhanced Keyboard, the Space Saving Keyboard had the Model M manufacturing designation. Part number 1391472 is one such variation. Another is 1392934 (which was made around 1987).

==Features and design==

The number pad was integrated with the keyboard. Shift-NumLk would switch normal alphabet keys to keypad function. The top row 7, 8, 9 keys stayed the same, the U, I, O keys became 4, 5, 6, respectively, and J, K, L became 1, 2, 3, respectively. Lastly, M became 0. If Shift was pressed while in NumLk mode, those keys became navigation keys, with the same functions as the dedicated keys down the right side of the keyboard (Insert, Home, PgUp, Del, End, PgDn and the 4 arrow keys).

Unfortunately, the keyboard has no lights to indicate the mode of the keys.
