NAME

     rbox -- HP98720 ``Renaissance'' graphics device interface


SYNOPSIS

     rbox* at dio? scode ?
     wsdisplay* at rbox?


DESCRIPTION

     This driver is for the HP98720 and 98721 graphics device, also known as
     the Renaissance.  This driver has not been tested with all possible com-
     binations of frame buffer boards and scan boards installed in the device.
     The driver merely checks for the existence of the device and does minimal
     setup.

     The Renaissance can be configured at either the ``internal'' address
     (frame buffer address 0x200000, control register space address 0x560000)
     or at an external select code less than 32.  At the internal address it
     will be the ``preferred'' console device.  The hardware installation man-
     ual describes the procedure for setting these values.
