Applications

Decision Data produced display terminals primarily for use with IBM midrange computer systems — notably the IBM System/36, System/38, and AS/400 (iSeries) platforms — as well as their own proprietary office systems sold primarily into banking, insurance, and corporate data-entry environments during the 1980s and early 1990s. These terminals functioned as dumb or intelligent display stations, relying on a separate logic or controller board (or a standalone controller unit) to handle the host communication protocol, with the display unit providing the CRT screen, deflection circuitry, and power supply. The "No Logic" designation on this unit means the display housing and CRT are present, but the internal logic/controller board that handles the actual data communication has been removed — making it suitable as a parts or restoration source, a display prop, or a project for collectors restoring vintage terminal systems. By the mid-1990s, PC-based workstations had largely displaced dedicated ASCII and 5250/3270-type terminals in most business environments, making surviving examples of this era increasingly collectible among vintage computing enthusiasts.
