Description
Decision Data C1410A Terminal Keyboard RJ-11 5V DC Vintage IBM Midrange System
The Decision Data C1410A is a dedicated terminal keyboard designed for use with Decision Data display terminals and compatible EDP/midrange business systems. It connects via a coiled RJ-11 cable and draws 5V DC at 50 mA maximum from the host terminal — it is not a standard PC keyboard and must only be connected to designated compatible systems, as noted by the manufacturer's warning label on the underside. The keyboard features an extended layout with a full alphanumeric section, a numeric keypad, and a prominent bank of 22 Cmd (command) function keys arranged across the top row.

Applications
Decision Data was a US manufacturer of IBM-compatible display terminals, primarily serving banking, insurance, and general business data-entry environments during the 1970s through the 1990s. Their terminals were designed to emulate IBM 3270 and similar midrange/mainframe display protocols, and keyboards like the C1410A were purpose-built to match the function-key conventions those systems required — hence the Cmd1–Cmd22 row, which maps to host-application commands rather than generic PC functions. The RJ-11 interface and 5V host-powered design are characteristic of that generation of dedicated display terminals, where the keyboard drew its power directly from the terminal unit rather than from a separate supply. Today, these keyboards are primarily sought by collectors of vintage computing equipment, by organizations maintaining legacy Decision Data terminal installations, and by enthusiasts of pre-PC business computing history.
This Decision Data C1410A terminal keyboard has been inspected and appears to be in good used condition. The keycaps and body show light yellowing typical of vintage equipment of this era, and the numeric keypad area has some additional surface soiling visible in the photos. The coiled RJ-11 cable and connector are intact. No cracks or broken keycaps are evident. Please review our photos carefully and contact us with any questions before purchasing.
