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, john chapman ...{watmath,ihnp4,uw-beaver}!ubc-vision!sfucmpt!sfulccr!chapman
