  1. I think the only way to get a CX55 working with an AV mod is to use one of those cheap AV mods you see all the time for the 2600 and 7800. The 5200 actually uses the exact same RF modulator as the 2600, so it would definitely be doable. The video quality wouldn't be all that great but beggars can't be choosers I suppose.
  2. I never understood why they even attached the Intellivision name onto the thing to begin with. The only thing that reminds me of the original is the controller, which if I'm honest, shouldn't be something to ape for a modern console. IMO an updated version of the Intellivision Lives compilation would've been much better and much more respectful of the Intellivision name than gambling on a whole new console. Also, I wasn't really active much when Tommy was around and I have to say I'm pretty damn ashamed with how that fiasco went down. Moreso because some people who I thought I respected in this community fell for this conman and let him run rampant like he owned the place...
  3. My 2800 arrived today, everything was accounted for and in very good shape. As promised, I checked out the PSU and it was putting out close to 12V AC without a load. However, when I plugged it into the 2800 and measured the voltage input to the 7805, I was getting about 13.5V DC and the heat sink got pretty toasty as a result. Definitely wouldn't recommend using the original Japanese AC adapter unless you need to perform a quick test or something. Also, I was curious about the RF modulator since it seems to be the only internal difference between the Japanese 2800 and the SVA II. It's part number CA019628 which I found zero information on, so this is definitely a 2800-specific part and not a typical 2600 RF modulator that was simply retuned.
  4. Both the SG-1000 and ColecoVision use similar VDPs (9918 for the SG1K, 9928 for the CV) whose graphic modes were not included in the Genesis/Mega Drive VDP. Technically they do work, but you'd be playing them blind because the Genesis/MD would just display a black screen for those games.
  5. You can actually download them all in one go (as PDFs) in a zipped archive on the Archive page. If you click on where it says "PDF", it'll collapse the list and show a download icon for all the PDFs like this:
  6. This is pretty close to what you're looking for: https://archive.org/details/ImpossibleMissionUSA/Ace of Aces (USA)/ The 7800 system manual isn't included but it's on the Internet Archive as well.
  7. The RT5X is only for scaling analog video to an HDMI display, so unless you're using RGB from the SOPHIA 2 or both systems' original video outputs, it's unnecessary. You'll need a DVI to HDMI cable plus an audio injector since the SOPHIA 2 doesn't carry audio over DVI.
  8. Depends on the charger, a lot cheap ones are poorly designed/built and can throw off a ton of interference. I once used a cheap knockoff MacBook charger and it would create interference with literally anything else that was plugged into the same outlet or power strip.
  9. No, you just need to tune into either channel 95 or 96, which are roughly equivalent to Japanese channels 1 and 2. There's pre-modded Famicoms out there, but a lot that I've seen are poorly done. I'd actually recommend hunting down an AV Famicom or even a Twin Famicom if you can afford it, as those have composite output.
  10. The Pi1541 is also a great choice, and has better compatibility than the SD2IEC since it emulates a full 1541: https://cbm-pi1541.firebaseapp.com/
  11. Anyone win this? Was thinking of putting in a bid but I see it escalated pretty quick https://www.ebay.com/itm/295628257260

    1. x=usr(1536)

      x=usr(1536)

      Had a watch on them, but when I saw the bids climbing I bailed.  Honestly a bit surprised they fetched that much - they look to be pilot run controllers, not actual prototypes.

      interesting auction. I don't remember if my system x has proto controllers or not.

      Neato!

       

      I was mostly surprised as it was the only auction on eBay of 5200 controllers that left out the word "Untested" and didn't say "For Parts/Repair"  😛

  12. And honestly I don't think Coleco was too concerned about Atari in the home computer market, it seems like they saw Commodore as their main rival in that space considering how aggressively priced the Adam was.
  13. S-video as a standard was introduced in 1987 along with the S-VHS format, though the idea of separating out chroma and luma signals for better picture quality goes back further than that (i.e. Atari 800, C64). Up until the mid-1990s you only tended to see it on high-end TVs and professional monitors, so most people just used composite or RF instead. I think if you wanted an S-video cable for your SNES, you had to contact Nintendo for it which is why official S-video cables are fairly rare.
  14. I'm pretty sure he's actually talking about plugs that sit closer to the wall and have the cord go off at a right angle.
  15. There seems to be quite a few of them for sale on Mercado Libre at any given moment. From some of the other evidence I've seen thus far, they seem to be internally identical to the SVA II (meaning their RF modulators are tuned for US channels 2 and 3) and not just Japanese 2800s dumped in another market. Another interesting thing I noticed is that the PSU in the lot I linked to has a 1984 date code (1884), so the 2800 might have been released there in the months leading up to the Tramiel switchover.
  16. While we're on the subject of power supplies, I've noticed that the 2800s that I keep seeing for sale in Mexico have the same one bundled with the SVA II, like this one here: https://articulo.mercadolibre.com.mx/MLM-2034862996-atari-2800-_JM I'm curious if anyone else has one of these Mexican 2800s...
  17. Transverse plug blades are not a thing for US outlets, I think you're talking about a right-angle or flush-mount plug and not the actual blades. In any case you can just get these: https://www.amazon.com/Cable-Matters-2-Pack-Profile-Extension/dp/B074PWTQG4 Also what 5200 model you have is irrelevant, both the 4-port and 2-port 5200 models have largely identical power circuitry so anything that works on one is fine with the other.
  18. I've also used a 12V supply on my 5200, and like you absolutely nothing bad happened. Plus the heat sinks on the 7805s are pretty big so they can take the heat no problem. It's also worth noting that there's an official 5200 PSU which puts out 11.5V...
  19. I don't recommend those at all, they're very cheaply built and will generate excessive interference. Grab one of these instead: https://console5.com/store/triad-magnetics-power-supply-for-atari-5200-twin-famicom-pal-snes.html
  20. On my SVA II I just use the same 9V DC Triad that I use with a load of other systems, and the 2800 won't be an exception. I just want to examine the 2800 PSU and get some information out there.
  21. When mine gets here I could check to see what kind of voltage that brick's putting out. Some Japanese PSUs are fine and dandy with 120V, but there are a few (i.e. Famicom HVC-002) which do put out considerably higher voltage and heat with 120V. In those cases it's honestly much better to use a different PSU than go through the trouble of using a stepdown converter.
  22. Given that the oldest examples of the 2600 are approaching 50 years old I wouldn't be surprised if that was the case. I know in the analog synth world I've seen 40xx logic ICs fail simply due to age too.
