More on this type of keyboard...
The Model M8 is a 50-key point of sale keyboard with a tilt-adjustable 2x20 LCD screen and integrated magnetic stripe card reader in the Retail POS (RPOS) series of POS input devices. The M8 was originally known as the IBM Retail POS Keyboard with Card Reader and Display. Its earliest host system was the IBM 4694 POS Terminal Model 001 announced in June 1993 and it was a successor to the IBM 4680 series 50-Key Modifiable Layout Keyboard and Operator Display (also known as the IBM 4680 Combined Keyboard/Display). For the most part, the layout and function of the M8 are customisable and the keypad has many transparent keytops to facilitate printed or written legends on paper. However, almost all M8s have a dedicated numeric keypad in the middle key bank and a "Ctrl" key in the bottom-left. After Toshiba TEC acquired the IBM Retail Store Solutions division in 2012, they continued producing the M8 under their own branding.
