The IBM Modifiable Layout Keyboard was one of five Model M POS input devices introduced with the IBM 4694 POS Terminal in June 1993. The Model M11 is a variant of the Model M9 ANPOS MSR Keyboard entirely constructed of single-unit relegendable keycaps excluding the dedicated numeric keypad on the right side of the keyboard and the Ctrl key located on the top-left most key. The M11 can be configured for entirely functional use or as an ortholinear alphanumeric keyboard.
