Applications

The NCR 4950 was designed for use with NCR's ADDS 4000 series ASCII terminals, which were widely deployed in retail, banking, and data-entry environments during the 1980s and early 1990s. NCR's ADDS (Applied Digital Data Systems) terminal line was a major presence in point-of-sale and business transaction systems of that era, and keyboards like the 4950 served as the primary input device for operators working with character-based, host-connected terminal sessions. Today these keyboards are sought by organizations maintaining legacy NCR terminal installations, vintage computing collectors, and system integrators supporting older NCR-based business software environments. The ASCII layout and dedicated function key column were standard for transaction and data-entry workflows of the period.
