I could only get it to work at 640x480 on my Diamond Speedstar. At 800x600 all I got was a pink screen. A Paradise OEM card worked fine at 800x600. I wanted to try it on an ATI 8514 clone, but as someone already mentioned most 8514 cards don't have the VGA feature connector. >One thing that really bothers me is that it does not work with >system with more than 15M of memory. (I had 16 M memeory on my system, Yea! this is a real bumber. Anybody with a 16 or 32 Meg machine is SOL Since the V-Blaster's 1 MB frame buffer is mapped into a user defined area in the 8-15 MB memory space. Another potential problem I noted with V-blaster was it's lack of a S-VGA input. The fact that V-Blaster uses the VGA feature connector might be a problem if you have another card (ie. a VGA to NTSC Genlock card) that uses the feature connector. >The image quality is not as sharp as I expected.

Even a $2000 (US) Targa board seems to come up short in this regard. The Video Blaster and the software that comes with it seem to be targeted at those users who need to create a PC based multi-media presentation us. video sources. At about $400 US it's hard to beat for this application. >with -- +-------------------------+-----------------------------------------------+ | Ralph Engwall | Q: Why am I banging my head against the wall? | | engwall@mtha.usc.edu | A: Because it feels *so* good when I stop. | | uunet!usc!engwall | |
