Possible to get S-Video output from TI-99/4A?

[Albert]

I'm at the Houston Arcade Expo this weekend, and there is a TI-99/4A setup in the retro consoles/computers area. Someone asked me if it's possible to get separate chroma and luminance outputs from a TI-99/4A to hook up to the back of a Commodore 1702 monitor. I didn't know the answer, but I told him that the experts in the TI-99/4A forum here would be able to tell me in under five minutes.

 

Thanks!

Hi,

 

I think the best possibility is the F18A-Video-Board, this is for a brilliant VGA-output and 80colums:

(but the important question here is if that works with this monitor here !)

But there are more options, means also some smaller mods on the existing equipment, but i am not the specialist here

I watch out now for some links, but I am sure there will be qualified answers here soon

/EDIT/ some links:

(but please be aware that I am oblivious to the 1702er monitors (and many other things)

there are many composite to svideo adapters out there that can be used with any composite video signal. Not sure how well they would work as far as video quality though.

This thread says "no", or rather you would need to get a 9928 chip and quite some work to adjust the signals to even match modern day component video, much less S-Video. On the good hand, the 1702 might actually support the progressive signal that modern TV:n would choke on. If I recall correctly, the C64 etc also produce progressive signals.

Yarrrr, yah, that be my thread, matey In short, S-Video is YIQ not YUV, which is a slightly different signal but enough to not provide color. My recommendation: get a good passive composite-to-SVideo adapter or get an F18A and go SVGA.

 

I have purchased a few of the composite adapters and have surprisingly good results with nice clear output. I will try to post some pictures up this weekend if I have time.
