The IBM Modifiable Layout Keyboard was one of five Model M-designated POS input devices introduced with the IBM 4694 POS Terminal in June 1993 and is a 133-key point-of-sale matrix keyboard or "key array". The Model M11 is a variant of the Model M9 ANPOS MSR Keyboard constructed entirely of single-unit, transparent keytop keys (excluding the dedicated numeric keypad and the Ctrl key located at the top-left corner). The M11 can be used as a functional keypad or an ortholinear alphanumeric keyboard. After Toshiba acquired the IBM Retail Store Solutions division in 2012, Toshiba Retail continued producing the M11 under their own branding.
