Choclo Posted March 28, 2023 Share Posted March 28, 2023 Hello dear community, I bought some Atari 2600 paddles on Ebay the other day, the buyer was so nice and just packed a surprise for me. 🎁 I had to laugh a lot when I saw it, I have never seen such a thing before. It's an Interton Video 3000 that was released in 1976. Of course I plugged the console in straight away, but unfortunately I can't get a proper signal from it. I can see that there is a signal, but that's the best I can manage. In my photos you can see that there is a signal and that the console also works (0:0) The console is powered by a 9 volt block battery. On the console itself, you can readjust the frequency. Does anyone have an idea how I can get this jewel to work? Is the signal from it perhaps too weak? Thanks a lot Cheers Choclo Quote Link to comment Share on other sites More sharing options...
carlsson Posted March 28, 2023 Share Posted March 28, 2023 Try a much older CRT TV if you have one. The older, the better when it comes to old consoles like this one. 1 Quote Link to comment Share on other sites More sharing options...
CatPix Posted March 28, 2023 Share Posted March 28, 2023 (edited) Or use a VCR tuner. But yeah, CRT made after 2000 in Europe usually have a very hard time picking up console signals. Also, those consoles were almost never pre-tuned to a defined canal so you should also try to use fine tuning as it's unlikely the signal is precisely on canal 36. I suppose you tried to tune the signal on the system itself? Edited March 28, 2023 by CatPix 1 1 Quote Link to comment Share on other sites More sharing options...
Choclo Posted March 28, 2023 Author Share Posted March 28, 2023 (edited) Ooooh... This is going to be exciting. 😛 The only thing older than that is my JVC Videosphere (1970). 🚀 I will definitely try that out. Many thanks and best regards@CatPix Yeah, i tried every single mhz 😅 also in the system itself. Edited March 28, 2023 by Choclo Quote Link to comment Share on other sites More sharing options...
CatPix Posted March 28, 2023 Share Posted March 28, 2023 Your Videosphere should be perfect! This system is most likely B/W anyway ^^ 1 Quote Link to comment Share on other sites More sharing options...
carlsson Posted March 28, 2023 Share Posted March 28, 2023 That is assuming the Videosphere lets you tune in channels continuously. I know in the early days the VHF channels 5-12 and 2-4 (speaking Europe here) tended to be fixed with e.g. a rotary wheel while UHF 21-69 was free flowing if the TV even supports UHF frequencies. Many of the oldest consoles tend to use low VHF frequencies but every now and then you come across one in the UHF range. 1 Quote Link to comment Share on other sites More sharing options...
CatPix Posted March 29, 2023 Share Posted March 29, 2023 I never seen a TV set made after the early 60's with a rotactor for frequencies. Tho I guess the French market was odd on that point. The screen shows channel 36 but it could be "ghosting" and the main picture could indeed be on the VHF range. 1 Quote Link to comment Share on other sites More sharing options...
carlsson Posted April 1, 2023 Share Posted April 1, 2023 Yeah, it probably depends on the size and price range of the TV how it was made. I have this one (or a very similar model), made in 1980. https://www.radiomuseum.org/r/sharp_radio_cassette_tv_10p_28g.html Quote Link to comment Share on other sites More sharing options...
Choclo Posted April 3, 2023 Author Share Posted April 3, 2023 It worked great on the Videosphere! The picture dances up and down a bit, but it works. 😄 Of course I would have preferred an AV mod, then I could simply switch it to the Atari and the Intellivision via an AV switch. Well, you can't have everything. Now I had to look at the rotary potentiometers, they are still quite inaccurate. (maybe just clean it) @carlsson The Radio Cassette TV is awesome! 1 Quote Link to comment Share on other sites More sharing options...
carlsson Posted April 3, 2023 Share Posted April 3, 2023 Depending on how the signal is generated, it might be fairly straightforward to use one of those 2-3 resistors + 1 transistor kits to get composite (B&W) video out of it. Quote Link to comment Share on other sites More sharing options...
Choclo Posted April 3, 2023 Author Share Posted April 3, 2023 I have done an av-mod on the atari as well as in the intellivision, but all on instructions. I can only read and solder... 😬When I find the time to clean the potentiometers, I'll take a photo of the inside. 1 Quote Link to comment Share on other sites More sharing options...
carlsson Posted April 4, 2023 Share Posted April 4, 2023 Me too, but generally it seems if you can find one video signal, the circuit to amplify it is pretty much the same, small variations on the resistances perhaps. 1 Quote Link to comment Share on other sites More sharing options...
