IBM 2245

The IBM 2245 is a display station introduced by IBM in the mid-1960s. It was a vector graphics terminal used primarily with IBM's System/360 mainframe computers. The 2245 allowed users to interact with the computer using graphical representations of data rather than purely textual output, which was common at the time.

The terminal displayed images on a cathode ray tube (CRT). Unlike raster graphics displays, the 2245 drew lines directly on the screen, controlled by commands sent from the mainframe. This meant that the images were composed of vectors, hence the term "vector graphics."

Key features of the IBM 2245 included a light pen, which allowed users to select and manipulate displayed objects. This provided a more intuitive and interactive experience compared to traditional teletype-style terminals.

While the IBM 2245 was a significant step forward in computer graphics display technology, it was relatively expensive and complex. Consequently, its use was generally limited to specialized applications in areas such as computer-aided design (CAD) and scientific visualization. The 2245 was eventually superseded by more advanced and affordable graphics terminals and raster graphics technologies.
