No.  The maximum color redition is 64K colors on screen from the usual
256K pallete.  I think this extended color mode works only at 640x480.

The usual VGA resolutions plus 1024x768 interlaced.  All resolutions are
in 256 colors.  It can run 8514/A-specific apps.

Only a PS/2 version is out.

The usual range for graphics coprocessor boards ($900-$1500.)  It might
be a bit cheaper.

This board doesn't have an 800x600 mode because it is NOT a SuperVGA
board.  This is basically what the 8514/A standard should have been,
although it is STILL interlaced at 1024x768.  It comes with a Windows
1024x768x256 driver and was developed with Windows in mind.  XGA also
has some sort of buffering scheme as it will be part of the DVI package.
One last thing:  IBM is talking to VESA about providing a VESA driver
and IBM is being rather open on the design specs.
