I too would really like to see a review as I'm seriously considering buying
one of these boards - particularly since it will be with my own $$.

One thing I'd like to know is whether or not the Targa-16 (or others)
have colour lookup tables so you can do gamma correction - if not has
ATT tried any kind of 'average' gamma compensation on the rgb outputs
in the board design?

Also I assume the 512k of the 16 is not mapped in one window into the
pc's addressing space - so how big is the window and how do you switch
it?

What other parameters can you control on the board?

Is it possible to upgrade a 16 to the other (24,32) versions?

Thanks in advance for any info,
