pnozz0 at sbus? slot ? offset ?
The pnozz is a color frame buffer with graphics acceleration, embedded in the Tadpole SPARCbook 3GS, 3GX, 3TX, and 3XP laptops. It is based on the Weitek Power9100 video processor and an IBM RGB525 RAMDAC. If the sparc/tctrl(4) device is also configured, the pnozz will be pow- ered down when the lid of the laptop is closed or the screen is blanked.

There is currently no way to switch back and forth from the onboard dis- play to the external connector. It is not possible to change resolutions or color depth. NetBSD 10.0 February 17, 2017 NetBSD 10.0
