Sorry to rehash this subject.. I didn't pay attention when this was
discussed awhile back. We're looking for a HARDWARE ONLY solution that
will display VGA output on NTSC, Supervideo, or Super VHS monitors. I'm
aware of US Video, Willow VGA-TV, and another device that consists of a
box and a device driver that converts VGA signal to NTSC. Does anybody
have comments on this subject?? Many thanks in advance..
Tim.

Many thanks in advance.. Yes, we want HARDWARE ONLY and therefore converts in realtime (ok, I want to play games off my 20" TV set, amongst other things). Hopefully it will cost less than $500. Does anybody has that VIN thing ($399, I think)? Does it do realtime? I called the company (advertised in Computer Shoppers) but could not make head-or-tail with the guy on the other end. I suspect he was trying to confuse me (into buying) because the VIN does not do realtime (like I want it to). Nonetheless, I hope I am wrong and can use the VIN for the purpose.

I don't recall what was discussed previously, but the manual for my ATI VIP card (8-bit vga) suggests that ntsc video is available from pins on the card. I haven't tried it myself.

Thanks for pointing that out. Which pins are you referring to? I just looked through my ATI VGAWonder manual and didn't see anything out of ordinary. I dug out my October 1990 issue of Radio Electronics and found the article on a device that converts NTSC->VGA from Harmonics Research in New Jersey (201) 652-3277. I decided to call them and was delighted to find that they also have a device that converts VGA->NTSC/S-Video for ~$120 (I don't remember the exact price) in kit form and $283 assembled. We will probably give this a shot. I also got this in mail: } Tim, I think we may be able to help you. We manufacture an SVGA board } that can provide an NTSC recordable output in all standard VGA modes } as well as several extended modes, including 640x480x256. } } Give us a call at (512) 346-5781 and ask for Carrie Cavanaugh. The following is an article also posted to comp.sys.ibm.pc.hardware, included here for reference in case some of you missed it. } About a week ago, I requested info on VGA--> composite video } cards. } } Here's what I've got so far: } } 1. IEV corp. Salt Lake City, UT 801/466-9093 } VGA Broadcaster board does VGA--> composite. $695. } They also make some similar boards for NTSC/RS-170, } S-video & RGB/synch RS-170. } } 2. Avacado computer. Silver Spring, MD 301/593-5586 } VGA-TV card can do composite output for the various video } modes. 64 shade gray scale or 256 color. 256K mem std, } expandable to 512K for $61. Base cost of card was } quoted to me on the phone as $499 but is listed as $699; } they offer a 5% education discount. } } 3. Video Associates Labs Austin, TX 512/346-5781 } Microkey/A card: A rather sophisticated card which can } handle up to superVGA (1024 x 768). Of course composite } video can't handle anything more than normal VGA, at } least as far as I know.

I would be interested in seeing any other information you get on this. I would like to hook my laptop up to a TV. Mike before May 25: mheyda@heyda.austin.ibm.com after May 25: gt6681c@prism.gatech.edu Thanks.
