Variant of a Model M 4680 POS Alphanumeric Keyboard

The IBM 4683 and 4684 were point-of-sale (POS) terminals for the IBM 4680 Store System. The 4683 was first announced in January 1986 and is known for being IBM's first PC-based POS system, with the 4684 arriving later and differed by being able to function as a terminal controller. The IBM 4680 POS Alphanumeric Keyboard was available for either terminal and is presently the only known buckling spring point-of-sale input device released by IBM. They have a PC/AT-style physical and functional layout and their inner keyboard assemblies match the design of the slightly earlier Model M-based IBM 6770/6780 System Movable Keyboard. The layout makes them a sort of "Model M/AT" if you will. The keyboard sported a double-ended modular cable with 8-pin SDL connectors and communicated in IBM Serial Input/Output (SIO) scancodes via RS485. Inside, they sported a speaker and a Honeywell/Micro Switch V3L-2174-D8 roller lever limit switch for registering key-lock position. This keyboard should not be confused with the SMK-made IBM 4680 Alphanumeric POS (ANPOS) Keyboard released around the same time. The 4680 POS Alphanumeric Keyboard was withdrawn from marketing in April 1992 without a like-for-like replacement and was instead substituted with the aforementioned SMK-made ANPOS Keyboard.
