IBM-made 18-key peripheral component of the IBM Screen Reader series, pioneering screen reader software designed to help people with hard or lack of sight access a PC. It had a telephone-style keypad layout (1, 2 and 3 at the top instead of 7, 8 and 9) and notable "HELP" and "STOP" keys. Despite being a keypad, these normally plug into a PS/2 mouse port and will not operate correctly through a PS/2 keyboard port and without its original software.
