Line 1: '''GDDM''' ('''Graphical Data Display Manager''') is a [[computer graphics]] system for the IBM [[System/370]] which was developed in [[IBM]]'s [[Hursley]] lab, and first released in [[1979]]. GDDM was originally designed to provide programming support for the IBM 3279 colour display terminal and the associated 3287 colour printer. The 3279 was the first colour graphics terminal that could be used in a general business environment. GDDM was extended in the early 1980s to provide graphics support for all of IBM's display terminals and printers, and ran on all of IBM's mainframe operating systems.
