  1. Hello masters of Atari hardware, I have had a product idea that's been kicking around in my head for ages, and I wonder why no-one has built this product.  Perhaps you can offer some insight?  Scenario: a product that enables me to play h2h Atari games on real hardware on a real CRT where the other player doing the same thing, but over the Internet.  I was imagining a bluetooth device you could plug into the DE9 on the back of the Atari that syncs with an app to send/receive control inputs from the other player, who also has one of the same on the other side.  Video/audio is outside the scope of the product and is well handled by other solutions: Point the camera at the screen and use Teams/Zoom/Jitsi/Facetime/etc.  Why does this not exist?

    For Harmony and Melody, multiload Supercharger games load the next part (and the first part for that matter) pretty much instantly, because they can. All the parts of the multiload .bin are all right there in the flash memory itself already. I suppose that the load bars could be faked, but I didn't see the point in that because there is no actual loading taking place.

    Hello @batari, does this mean the Harmony cart supports Supercharger games?  I just bought one now that @-^CrossBow^- helped me complete my AV mod on my Jr.  I am looking forward to playing four way party mix for Ferg's podcast.

    I meant to come back to this post and reply further but I forgot.  I think @-^CrossBow^- is onto something.


    Also, the video shows that you have audio and SOME kind of video signal, but the sync is all messed up. I’m not familiar with these inexpensive a/v mods (my systems all have UAVs in them), but speaking generally the NTSC sync signal is provided on the Luma channel of the video signal output. I’d have to dig up Jr. schematics and puzzle out the wiring to be sure, and then try to grok the simple a/v mod circuit, but your TV is certainly not getting a good sync signal on the video. That much is clear. 

     

     

    Thanks for the thoughts.  I will move the red wire from the collector to the emitter and report back.

     

    I had never heard of a UAV before. But I found this excellent video here. 

     

     

    As this is my first attempt at modding, I am glad to see the endorsement in the video of choosing a cheap simple mod first. If I am able to get this going, maybe I will get another system and try the UAV mod with it.

     

    Thank you so much for coming along for the ride.

    Might be more cost effective to send your current jr to another to look it over who might be able to get it going for you cheaper? Did you already install and wire in the AV output jacks?

    That would be ideal.  Yes, I am at the step where you are supposed to adjust the pot, but because the video doesn't work I can't perform that step.  I would love to be able to send it to someone to take a look.  I'm attached to this hardware as it's the same unit I had from childhood.   As I showed in the YouTube at the top of the thread, the audio works, and there *is* a video signal.

     

    Do you have a recommendation for such a person?  I was willing to spend $60 on an auction (but was outbid), so that gives a pricepoint.

     

    Thanks?

  5. Hello everyone, given that my AV mod failed, I would like to buy a pre modded jr. Rather than just going on eBay, I would like to ask here. Does anyone have a recommendation for how to buy a pre modded 2600 Jr that would benefit our community?

  6. Absolutely! Thank you for your prompt response. I will post what I have, but I fear a synchronous Zoom or teams or Google meet session will be what I really need.

     

    You cannot see the A3 next to the TIA, but I would think that's okay given that the audio is fine.

     

    I have a multimeter, but I really don't know how to use it to diagnose the problem.

     

    In any case thanks for anyone who replies to this.

    Hello fellow at Atarians. I tried my hand at installing the AV mod on my original Atari 2600 jr. After wiring everything up I observe that the video does not work. Has anyone here successfully done this mod?

     

    Perhaps I could get some hand-holding in the form of a zoom or teams or Google meet session.

     

    Attached is is a photo of the actual mod kit board I used.

     

    I expect it is just crappy soldering on my part. But before I go and undo everything, I would like to have some reassurance that there isn't something else I've done wrong.

     

    These are the specific Instructions I followed.

    A little help?
