Converting to composite AV without modifying the case?
« on: February 10, 2012, 11:52:38 AM »
Hi all, I recently got a US TG-16.  You may recognize my name from other forums like Atari Age or Digital Press.  Anyway, I've seen the simple looking modification instructions to convert a standard composite av cable to connect to pins on the expansion port.  So my question is, is it possible to do so with say small right-angle connectors, so that the wires would fit in there with the standard TG back case cover on?  I know with it on, it's right flush on the exp port.  If the answer is yes, would anyone be willing to make a cable for me?  I am simply useless when it comes to soldering.  I'd prefer a thin AV/RCA cable, maybe a 6 footer, because I would want to run it through that small opening on the cover that the AC adapter plug goes through.

I used to put the 3 rca jacks on the back of the case and route the cable through a notch in the rear cover, just like the ac adapter, easy. Pic.

The notch is a little small so you may have to file it out in order to get all the cables in. I modded someone's TG-16 in this way and probably the trickiest part is getting the jacks positioned in a way where they won't touch the motherboard.

Well I'm not interested in doing anything with the motherboard.  I just want to plug into the audio and video out pins on the external port, and prefer to have it fit in place with the back cover still on.  Anyone know who would be interested making a cable for me?

Exactly that's it, as long as it would fit inside the cover.  I'd like something like that with like a 6 foot thin composite cable.  I say thin because I need it to fit through that small opening in the cover for the AC plug.  I've seen the instructions to alter a cable, but I am a disaster soldering.

I could make such a cable, but I dont have the materials. that being said, you need to consider a few things. I'm pretty sure that a shielded cable is highly recommended. Also, Steve discovered that you really should have caps on those cables to prevent damaging feedback into the system.  Steve can correct me on this, i believe you need a 220uf cap on the video and 2 10uf caps on the audio. Give steve a pm and get his feedback on this. I cant speak for him but maybe he will throw you together a set. He is very reasonable.

edit: yea thats right, i still got three of them.

I dont have everything that you would need. I have a connector that would attach well to the back of your turbo. I would still need the correct wire, caps, and rca jacks. If you bought the

parts i would make the cable. I'm awaiting word back from steve on what wire would work best. The wire has to hold your video as well as audio and might be a really tight fit if it would fit at

all.

for short cables shielding is not an issue.
longer runs it is
yes on the caps+ to the system  - to the plugs
