- It was over a month ago that I heard about a new Tseng based board. 4M of
- ram (upto 1240 * 1024 in 24 bit, all hi-color, 256 modes supported upto
- that resolution) and it plugs into the local bus.
- That is the logical extension. Paradise, ATI, Diamond and probably others
- are shipping 24 bit cards (only 640 * 480) that do all hi-color, 256 color
- modes upto 1024 * 768. These cards are in the $150 to $250 Cdn range and
- falling.
- I think that they will hold at the 640 * 480 resolution for a while. My
- bet is that the DACs are only good at the 640 dot frequency for 8 bit
- resolution. Pushing them to 1240 is a bit of a challenge (read as money).
- Within 6 months I would be surprised to see a SVGA board that did not support
- 24 bit.
- The question is where do you get the driver for OS/2? ATI is very responsive
- but 640 * 480 is a pretty limited resolution. 800 * 600 is ok and 1024 * 768
- (if you have a > 17" moniter) is great.
- If you want to write something fast for those cards watch out because the
- colors cross 64k boundaries (the 286 that crawled out of the 70s is still
- assulting us with it "virtious" segmented memory). We should have more info
- when the next computer show hits very soon now.
