Macintosh Portrait Display

The Macintosh Portrait Display was Apple's first full-page monitor for the Macintosh, a field Radius had pioneered with the Radius Full Page Display and matching video card in 1987. The Portrait Display was introduced with the Mac IIcx and the Macintosh II Portrait Video Card in March 1989 and uses a 15" vertical grayscale CRT. This display has a fixed resolution of 640 x 870 and uses a 13w3 connector instead of Apple's "normal" DB-15 video connector.
