SYNOPSIS
cgsix* at sbus? slot ? offset ?
DESCRIPTION
The cgsix is a memory based 8-bit color frame buffer. It supports the
minimal ioctl(2) calls needed to run X11.
There are two different kinds of cgsix cards, known variously as either
the ``LEGO'' or the ``GX'' and ``TGX'' (Turbo GX) display cards, come in
both plain and ``plus'' variants. The GX and TGX cards support a maximum
display size of 1152x900. The GX+ and TGX+ have additional on-board mem-
ory and can support displays up to 1600x1280.
The Turbo GX cards are somewhat faster than GX cards. In addition, the
GX cards are electrically incompatible with the Ultrasparc Sbus; only the
TGX cards can be used on these machines. The following part numbers can
be used to distinguish GX and TGX cards:
501-1481 Double width GX, revision 1
501-1645 Double width GX, revision 2
501-1672 GX
501-1996 GX
501-2325 TGX
501-2922 TGX
501-2253 TGX+
501-2955 TGX+
