The IBM Retail ANPOS Keyboard w/ Card Reader was one of five Model M-designated POS input devices introduced with the IBM 4694 POS Terminal in June 1993 and is a 116-key alphanumeric keyboard. The M9 has two distinct types of keys - the 60%-size alphanumeric standard keys and the transparent keytop keys its M7, M8 and M11 siblings use. Like its siblings, a dedicated numeric keypad is found within the transparent-topped keys and gives enough spacing between the alphas and itself to allow for a full Enhanced layout configuration if desired. Of note is that the M9 always comes with an ANSI left shift and ISO enter as part of its layout. After Toshiba acquired the IBM Retail Store Solutions division in 2012, Toshiba Retail continued producing the M9 under their own branding.
