This message is from Richard Outerbridge of Dalhousie University in Halifax, Nova Scotia, who has read-only access to news. I'm only forwarding it, so please reply directly to him by email if possible. The net address that's been working from our own ARPANET mail service is RAMO@AC.DAL.CA. I would like to be able to record some computer images on video tape for later redisplay in a classroom setting. I have access to several video boards at present all of which produce some form of analog RGB output, none of which produce NTSC/composite color signals. I think what I need is either a low cost converter from RGB to Composite, or a video card which has suitable video out capabilities. I don't need particularly high resolution but lots of colours would be very nice. I've already talked to lots of folks who think it ought to be do-able, but none who actually know how. Can anyone with any suggestions at all please contact me directly (as opposed to through the list where you might have seen this). I'm RAMO@DALAC (bitnet).

From your reference to your having video boards I am guessing that you are talking IBM|clone PC here as opposed to Atari|Mac|Amiga etc. The following is taken from an article the Aug 8-21 issue of _Bay_Area_ Computer_Currents_: | Jovian Logic (Fremont, CA [USA, of course]) makes an external box that | works with an existing VGA card. This makes it somewhat cheaper for a | user who already owns a VGA board. The box plugs into the VGA socket | at the back of the PC and then connects to a VGA monitor and to a | normal NTSC video socket on a television or VCR. The box, called VIN, | retails for $495. Jovian Logic can be reached at (415) 651-4823. | USVideo Inc. (Stamford, CT) produces a board called the USVideo | Recordable VGA. This is a separate card that should be used instead of | any existing VGA card. It costs $799 and has a built-in Genlock | capability, which the others lack. ... USVideo can be reached at | (800) 842-8780. | Willow Peripherals (New York, NY) produces the VGA-TV, another VGA card | with NTSC output. This, too, replaces any existing VGA card. It costs | $699. Willow Peripherals can be reached at (212) 402-0010. The by-line on this material is --Owen Linderholm. Thos Sumner Internet: thos@cca.ucsf.edu (The I.G.)

Tell us a little more about the RGB signals that you want to
convert to NTSC video. If they are standard horizontal and
vertical scan rates with interlacing then it may not be too
difficult. If they are non-standard then doing it cheaply
may be impossible.

It's just that nearly everything Richard was describing is what the Amiga would be the perfect, low-cost solution for! In fact, I think it might even be cost-effective for him to do just that (though I do not have his original requirements in front of me). It was not intended to be condescending or teasing in any way. But why walk a mile when a mere step is sufficient? As for Richard, he must weigh out the best solution based on his own time/money/resource constraints. That was just merely a suggestion and perhaps done in a jovial way. Is a sense of humor a crime around here? Geez, lighten up! :-) I've always wondered why some of the users of other computers get so up-in-arms when you even *mention* a different machine. Grow up. -- |*******************************************| -Compliments of /// |* All thoughts and comments are soley *| Fred Mitchell \\\/// |* thoses of The Author and has nothing to *| \XX/ |* do with Commodore-Amiga. *| Software QA - Commodore-Amiga |*******************************************|

[flame continues] > I've always wondered why some of the users of other computers get so > up-in-arms when you even *mention* a different machine. Grow up. Seconded. If you just want video-quality output the Amiga is a perfectly good alternative, and probably a factor of 10 cheaper than anything that's better. Some of the alternatives are a *lot* better, of course, but if price is relevent then it's worth at least a look. Disclaimer: I've got an Amiga. I also have an Atari, and I've used a wide variety of other machines. I recently recommended that my brother get a Macintosh for desktop publishing. I frequently recommend the Amiga on the net, because it's (still) way ahead of the competition for a number of applications... not because I bought one or because I swallowed CBM's marketing department. To the contrary, I put off buying any computer for over 6 years while waiting for something like it.

I didn't get upset because you mentioned (eerie music on) a "different machine" (eerie music off). I actually didn't even get upset. I just thought that he deserved a real answer to his question, not some possibly confusing suggestion that he was using the wroing hardware.

You know, maybe *I'm* using the wrong hardware! I mean, I could go out and buy an Amiga, and then I could rub elbows with all you mature guys! It'd be like maturing ten or twenty years!

I've recently purchased an analog-RGB-to-composite-video converter for my Atari ST, for a similar purpose. The device is called the "Video Key", and is manufactured by Practical Solutions of Arizona. I suspect that this box could be used with non-Atari hardware, but you'd have to replace the Atari-compatible wierd 14-pin DIN connector with something more appropriate. The Video Key is designed mainly for use with the ST's low-resolution mode, which is 320x200. Hardware palette only provides 16 colors, but there are a number of software hacks that produce 512+ colors by reloading the hardware palette on the fly, and this device faithfully translates those displays. It works at the ST's medium resolution (640x200), but the resulting picture is not very sharp and exhibits some ringing (not terribly surprising). Best of all is the price, $100. If nothing else, this should demonstrate that what you seek is possible and has been done. I've heard of a Motorola part (14xx?) which is supposed to be able to do this conversion, but know nothing about it. You might ask on sci.electroncs and rec.video, as well.

The Motorola part is the MC1377, "Color Televsion RGB to PAL/NTSC Encoder". Check with a Motorola distributor for specs, and application note AN932 "Application of the MC1377 Color Encoder". A rather inexpensive circuit can be built from instructions in the application note.

The net address that's been working > from our own ARPANET mail service is RAMO@AC.DAL.CA. I recently received a catalog from Personal Computing Tools which (page 25) describes a device called Video Charley which provides an add-on to extended EGA (they use the Paradise Autoswitch EGA 480) in the form of an additional card via the "features connector". This allows (according to their claims) gen-lock, keying and dissolve capabilities and 640 x 480 resolution. There are also three software packages offered at additional cost. The add-on is $749 and the Paradise board is another $399 if you get it from them with the accessory board installed and tested. This more expensive than some of the devices mentioned in my previous posting but it looks quite versatile. Does anyone have any experience with this device?
