I'd like to point out that 256 colors out of a 24 bit palette is BEAUTIFUL.
Not quite 24 bit, but VERY, VERY nice nevertheless.  At these kinds of
resolutions, 8 bits is great, 24 bit color is only needed in the most demanding
of applications.

Directly?  I'm assuming you mean via DIG (Device Independent Graphics).
Hmmm... That's interesting.  3 overlay planes huh?

What are the scan rates for the various resolutions?  What modes are
interlaced?  I only saw the 640x480.  I have a NEC 3D.  Seems like I jumped
too soon for too little.  Should have shelled out the extra bucks for a
better monitor.
