VCB03 Video Controller
From Computer History Wiki
The VCB03 Video Controller is an 8/24 plane color video M-bus subsystem for the VAXstation 3520/3540.
It has 1280 by 1024 resolution at 66 Hz display refresh rate, 3D hardware acceleration and (when fully configured) 24-bit true color.
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 (bits) per pixel; with it and its additional 16 planes added, it has 24 planes, providing full true color output.
