    Yes I'm using a modern LCD TV, though if you clip that one resistor that I mention for color that will tone down the intensity. I also imagine if you multiplied the values by 10 you would tone it done, it's the ratio of the resistors that are important. Still haven't tested for S-video but will.

     

    Merry Christmas!

    Ok I made instructions on what I did, I did not test for S-Video, if I get around to it I will try it but works pretty good for composite. The resistor values aren't common sizes, this is what I measured from the 4 pots that I then replaced with the resistors, I just mixed and matched to get values within a couple ohms. I really didn't see any improvement when I ran the outputs through a transistor for amplification and I have no idea if this conforms to composite standards (I'm sure it doesn't)

    Well after all that I ended up ditching all the circuitry, I had guessed that the resistor values for mixing the luminance were wrong giving me the bad colors. So I made a board with 4 potentiometers so I could adjust the mix and yup my guess was right, I ended up getting a good picture with no transistors, just a mix of luminance and chrome off the TC4050 already present in the junior. I'll post the values here later for future reference.

    Well I've seen about 15 mods for video for 2600's but all of them are for the large systems, not the junior. I've blown about a day here on trying things and have seemed to have gotten a good luma signal but the chroma is killing me, I just get tons of bleed or nothing at all.

     

    This is the mod I'm using: http://gamesx.com/wiki/doku.php?id=av:2600_s-video_mod and the luma is great, but the chroma seems to escape me. I really don't care if I get svideo it can be just composite but with all the color bleed the RF looks better (I've disabled the RF now in an attempt to get better color).

     

    I've searched and searched but nothing seems to pertain directly for the junior and the junior has a TC4050 built in (that's where I'm pulling the luma) anyone help?

     

    Thanks!!

    Well too late :P Got a Junior with 25 games (Pengo also which seems a bit rarer) 2 sticks and 2 paddles for $35 seems pretty good for an fleabay find, no one bidded so if it dies I won't be out to much, unit is tested though (at least claims to be).

    Will mod in a s-video. Still might be on the lookout for a 7800 and any game suggestions you all might have.

     

    Got these with the lot:

     

    Pengo

    Freeway

    Laser Blast

    Pitfall

    Robot Tank

    Stampede

    Circus

    Football

    Phoenix

    Pole Position

    Qbert

    Frogger

    Bowling

    Speedway II

    Codebreaker

    Berzerk

    Defender

    Asteroids

    Bowling

    PacMan

    Video Checkers

    Super Challenge Football

    Lock n' Chase

     

    Familiar with most of them

     

    Picked up a Yars Revenge (love that game) and might get a copy of Solaris and Atlantis also.

    I'm new here but looking to get a junior or maybe a 7800 to start off a collection, would love to find a lot with games, sticks, paddles, etc. Own a 1200XL, had it since new, but never had one of the classic systems. Would love to have at least Defender, Yar's, Bezerk, Atlantis, and maybe Solaris.

     

    Must admit not looking to spend tons, one of the reasons I want to get into 2600/7800 since it's a decently cheap system to get into. Doesn't have to be a super nice system, just something to get started on.

     

    Thanks!
