Math You Posted February 27, 2007 Share Posted February 27, 2007 Does anyone know if there is a composite video+audio mod for a PAL 2600 Jr? I've damaged the ferrite screw in the tuning inductor so converting it to composite is probably the only way I can get it working again. I'm not too good with electronics so something profesionally fitted would be best. Thanks Matt Quote Link to comment Share on other sites More sharing options...

Yes, you just need to wire the outputs to different pins, from memory it was 2,5,7,8 on the NTSC one and 2,5,6,7 on the PAL one, maybe vice versa. Of course converting probably costs more than a new Jr. these days...! Quote Link to comment Share on other sites More sharing options...
Math You Posted February 27, 2007 Author Share Posted February 27, 2007 Of course converting probably costs more than a new Jr. these days...! That's what I was thinking. I originally wanted a Flashback 2 but when I heard they weren't making a PAL version I bought a new 2600 Jr from France and some UK games to go with it. It's all getting very expensive Maybe I should have stuck with the emulator. Quote Link to comment Share on other sites More sharing options...
Math You Posted February 28, 2007 Author Share Posted February 28, 2007 Has anyone tried the composite mod that's on the Atari Age website? It only needs two wires and a jumper. It looks almost too easy..... http://www.atariage.com/howto/composite.html Quote Link to comment Share on other sites More sharing options...
Math You Posted March 1, 2007 Author Share Posted March 1, 2007 Well, I tried the composite mod from the Atari Age website and it didn't work. There was no sound and the picture kept scrolling up. Maybe it only works with NTSC consoles or one of the other 2600 Jr's. I did try connecting a couple of resistors together and got a very good black and white picture aswell as sound. What I don't understand is why the sound only came on when the picture was clear? I don't suppose anyone has a pin out for the stella chip?

Prodos8 Posted March 1, 2007 Share Posted March 1, 2007 Here's a schematic for the PAL Jr mother board with pinouts for the chips: http://www.atariage.com/2600/archives/sche...Junior_PAL.html Quote Link to comment Share on other sites More sharing options...
Math You Posted March 2, 2007 Author Share Posted March 2, 2007 (edited) Thanks for the link. I've been experimenting all day and think I've found something that works. It's all been trial and error though. At first the picture looked very bright with red looking pink and brown looking more like orange. I tried connecting another pin that made things look more natural. Here's a picture if anyone's interested. BTW. This is the 'attract' mode and not the actual game.

Math You Posted March 4, 2007 Author Share Posted March 4, 2007 I've only got Missile Command, Asteroids and Yar's Revenge. Photo's of the last two games didn't turn out very good as they have lots of movement. Was it a grey scale photo you wanted? Quote Link to comment Share on other sites More sharing options...
A.J. Franzman Posted March 4, 2007 Share Posted March 4, 2007 The photo itself doesn't need to be grayscale. That particular game and mode produces the Atari's full range of luminance outputs and is a good test of whether a video mod is producing the correct luma levels (many of which don't).

Math You Posted March 6, 2007 Author Share Posted March 6, 2007 Ah, I see. I'll try and find a cheap cartridge then post a picture of it. Matt Quote Link to comment Share on other sites More sharing options...
Math You Posted June 23, 2007 Author Share Posted June 23, 2007 The mod turned out pretty good but there's still some vertical lines spoiling the picture. Does anyone know if adding a capacitor to luma or chroma would get rid of them? Quote Link to comment Share on other sites More sharing options...
opeygon Posted June 23, 2007 Share Posted June 23, 2007 Would this help? http://www.8bitdomain.com/proddetail.php?p...9f58446ccc717ab I know most of you would probably rather do the entire mod yourself but I got one of these kits for a light sixer and loved it. Of course I'm not very skilled at all the techie things that most of you probably are good at. The good news is I'm getting better though! Modding my first atari was a hugh confidence builder, not to mention fun as hell! Next I'm going to attempt to refurb my personal heavy sixer. Thats gonna take a while but what the hell...

ATARImarcus Posted June 24, 2007 Share Posted June 24, 2007 Was anyone succsessfull with an pal 2600jr? I Have added composite and audio out to my pal 7800 some month ago and got a good picture, but also the 2600part would be very nice. I have all 2600 boxes (except the heavy sixer) so its not the problem to make an other mod with an black, ord light six. Quote Link to comment Share on other sites More sharing options...
Math You Posted June 25, 2007 Author Share Posted June 25, 2007 Would this help? [url=http://www.8bitdomain.com/proddetail.php? Looks really good. I wish I'd have waited a while before trying to mod the console myself. Quote Link to comment Share on other sites More sharing options...

The 8bitdomain stuff is really excelent, I have installed the 7800 one, and I am waiting for a 6 switch and 5200 one Quote Link to comment Share on other sites More sharing options...
Math You Posted June 26, 2007 Author Share Posted June 26, 2007 (edited) I tried this mod from a secam 2600jr but it didn't work. http://www.atariage.com/forums/index.php?s...=103217&hl= Edited June 29, 2007 by MRB Quote Link to comment Share on other sites More sharing options...
Math You Posted June 30, 2007 Author Share Posted June 30, 2007 This is what Ms Pac Man looks like with my own mod. I could have made the picture a lot brighter by moving one of the wires to another pin but I decided to stick with the darker picture. It's easier on my tired old eyes Quote Link to comment Share on other sites More sharing options...
Math You Posted June 30, 2007 Author Share Posted June 30, 2007 (edited) This is what Frogger looks like. Incidentley, whenever I collect the bonus frog from the moving log, the players green frog turns red so it cant be seen if you jump back to the middle section of the screen. Does anyone know if this is supposed to happen? Edited June 30, 2007 by MRB Quote Link to comment Share on other sites More sharing options...
ravenxau Posted July 29, 2007 Share Posted July 29, 2007 (edited) I did the mod as per MRB's pic in this thread - works great (better than some of the other ones on Australian PAL Jr's) a lot simpler as well - I will try to give it a few tweaks and see if it makes any difference Edited July 29, 2007 by ravenxau Quote Link to comment Share on other sites More sharing options...
Math You Posted July 30, 2007 Author Share Posted July 30, 2007 Glad it worked out ravenxau. I think that moving the wire on pin 6 to one of the pins next to it might make it brighter. Quote Link to comment Share on other sites More sharing options...
Math You Posted August 1, 2007 Author Share Posted August 1, 2007 I just tried playing Dragonfire on the modified 2600 Jr I've got, and noticed that the grey castle towers on level one don't appear but all the other coloured towers on levels 2,3,4 etc do?
