View source for VCB03 Video Controller

The '''VCB03 Video Controller''' is an [[M-bus]] double-buffered 8/24 plane color [[bit-mapped display]] subsystem for the [[VAXstation 3520/3540]].

Its memory is 2048 bits wide by 2048 bits wide, with either 8 or 24 planes in the frame buffer. It also has several custom [[integrated circuit|chips]] for high-performance video functions, and several onboard accelerators. It supports 1280 by 1024 [[resolution]] at 66 Hz [[display refresh]] rate, 3D hardware acceleration and (when fully configured) 24-bit true color. it also supports a [[keyboard]], and also a [[mouse]] or [[tablet]].

It consists of a graphics base module (L2004) and a graphics output module (L2005), and an optional graphics expansion module (L2006). Without the expansion module, it has only 8 planes ([[bit]]s) per [[pixel]]; with it and its additional 16 planes added, it has 24 planes, providing full true color output.
