    Well in looking at the actual manual on the 2600 installation from TBA it shows that on the 2600 side that Lum0 on the UAV isn't connected. So I'm guessing he has it wired properly. I guess I really need to do a 2600 install to see about making those instructions a bit more clear perhaps?

     

    If I'm reading this right...:

    TIA pin 8 (LUM0) - 1 on UAV

    TIA pin 7 (LUM3) - 3 on UAV

    TIA pin 5 (LUM1) - 2 on UAV

    TIA pin 9 - Co In on UAV

    TIA pin 2 - S (sync) on UAV

    That does look different than what I did, I may have been going off an older UAV board diagram. I will resolder to the above tonight and see how it works. So I will leave my "Co in" connection for now and do the other changes.

    Yeah, see my edit above for the manual excerpt. The 2600 LUM signals are basically moved “up” numerically one position on the board. That said, I looked closely at the TIA solder pics and it looks like pins 10 and 6 are desoldered? Is that an artifact of the lighting or were you messing around with something there? 

    Look like I screwed up there while working the others as they were so close and that capacitor (removed) was in the way, I will resolder those.

    I have the TIA on the left (CO104444-22, not D) and that is how I wired it.

    Maybe I will resolder the connections and see if it fixes the color issue. The color issues are there with RCA or S-video, so I think my UAV to S-video connections are probably fine and it's a TIA to UAV wiring issue. I'll try and order another UAV board a well. 

     

    Otherwise, the picture is incredibly sharp with the S-video and the stereo output is working fine, I can plug straight into my sound interface to record in GarageBand, which is great. 

     

    Thanks for the replies!

    I added capacitors and resistors connecting the left and right TIA audio pins as outlined in the stereo mod I found. Sound like its working, I'm recording using synth cart, plugging left and right channels into my audio interface and getting total separation of beats and lead like I wanted. My video wiring is jacked though, missing colors and getting video flicker. I actually created a separate post about it here with more photos of the attempt and the weird color issues. Hoping some experienced modders can take a look. Wondering if I need to cut any board resistors?

    UPDATE, missing colors after wiring:

     

    I followed my above diagram but as you can see from the images, a large section of colors are missing. Additionally after the first attempt Pitfall worked, but then stopped working, went to blue screen with a high pitched noise. After my attempt to fix, the audio and video do work but colors are still missing. The image flickers vertically sometimes when turning a game on, but stops after wiggling wires and doesn't come back. 

     

    Adjusting the color on the Atari or on the UAV board do not help the missing color issue. 

     

    Tested with Space Invaders, Pitfall and Air-Sea Battle. 

     

    In my attempt to fix I removed the resistor between pins 5 (or 6) and 9 on the back and resoldered pins 8 and 9. 

     

    Can anyone tell me what the pins control so I can try reconnecting what may be incorrect? Did I not interpret the wiring correctly?
    If I'm just missing certain colors, what could that mean? 

     

    PIN:

    2—SYNC

    5—LUM2 (2600 LUM1)

    7—LUM3 (2600 LUM2)

    8—LUM1 (2600 LUM0)

    9—COLOR IN

     

    Anyone see what I'm doing wrong?

    Hello! Looking for insights/support/expertise on UAV and stereo:

    I'm working on a Vader 4-switch 2600A UAV and stereo mod and am having trouble understanding which wires from the UAV goes to which TIA pin on my Vader 4-switch, and then which wires then go to the S-video and RCA sockets.


    The diagram of the board I found on another thread was somewhat helpful, but the TIA connections are unclear to me. Any diagrams of the pin layout so I can make the connections? Any diagrams of the image on page six of the installation manual? It's hard (for me) to decipher the photo with the wires twisted in the photo.

     

    I did try to make sense of it all and created the attached handy-dandy diagram as a proposal based on the different instructions, diagrams, images and mods I found on these forums and on YouTube (including the stereo mod which I think I want to do for Synthcart and live performance — two channels for sound and s-video to project the Synthcart visualizer.imageproxy.php?img=&key=f4dcc336a70d5c68imageproxy.php?img=&key=f4dcc336a70d5c68imageproxy.php?img=&key=f4dcc336a70d5c68 

     

    Does my diagram below make sense?
    Trying to be extra careful as this is my first mod and I'm inexperienced with electronics.
    I'm also guessing on which ground to run to the RCA connections, assuming any ground will do?

     

    UAV Mod

     

    PIN to UAV:

    2—SYNC

    5—LUM2 (2600 LUM1)

    7—LUM3 (2600 LUM2)

    8—LUM1 (2600 LUM0)

    9—COLOR IN

     

    S-Video seems clear, but if my diagram is wrong, please let me know. 

     

     

    STEREO MOD

     

    PIN to RCA (if stereo mod)

    12—capacitor—LEFT

    13—capacitor—RIGHT

     

    PIN RESISTOR CONNECTION

    12—resistor—5V solder pad

    13—resistor—5V solder pad

     

    Any insight or guidance appreciated!
    If I can nail this I'll build a better diagram to share with the community, could help noobs like me.
