The cgtwelve is a triple-slot SBus color frame buffer, with graphics acceleration and overlay capabilities.

The cgtwelve driver interfaces the frame buffer with the wscons(4) console framework. It does not provide direct device driver entry points but makes its functions available via the internal wsdisplay(4) interface.
