Apple Macintosh 12" RGB Display

The Apple Macintosh 12" RGB Display was released by Apple Computer on October 15, 1990 with the Macintosh LC and IIsi computers. It also supported other models of the Macintosh LC series. It was discontinued in March 1993, shortly after the introduction of the Apple Basic Color Monitor with the Macintosh LC III.

Description
The monitor used a shadow mask CRT with a viewable area of 11.5 inches that was capable of displaying 16.7 million colors at a resolution of 512 x 384 at 64 ppi. However, the original LC could only display 8-bit color (256 colors) in its base configuration. Upgrading the VRAM from 256 to 512 KB would allow it to support 16-bit color (thousands). It also supported a resolution of 560 × 384 to support the Apple IIe Card for the LC series.

Connector
The Macintosh 12" RGB Display included an attached cable with a connector (often misidentified as "DB-15"), a variant of the VGA display connector which was present on many Macintosh systems during the 1990s.
