DESCRIPTION

The cgone interface provides access to the Sun-1 system color graphics controller board, which is normally supplied with a 13” or 19” RS170 color monitor.  It provides the standard frame buffer interface as defined in fbio(4S). 

It supports the FBIOGPIXRECT ioctl which allows SunView to be run on it; see fbio(4S)

The hardware consumes 16 kilobytes of Multibus memory space.  The board starts at standard addresses 0xE8000 or 0xEC000.  The board must be configured for interrupt level 3.
