AppleColor High-Resolution RGB

歴史的背景

In 1987, Apple released two new monitors for use with the Macintosh II. The AppleColor High-Resolution RGB Monitor had a 13″ Trinitron CRT (the first Apple display to use an aperture grille CRT) with a fixed resolution of 640×480 pixels. The Apple High-Resolution Monochrome Monitor was a 12″ CRT that supported up to 256 shades of gray at a fixed resolution of 640x480. The Macintosh II was a modular system with no internal display and was able to drive up to six displays simultaneously using multiple graphics cards. The desktop spanned multiple displays, and windows could be moved between displays or straddle them.
