    Sheesh! First Nolan Bushnell and now this? What's with Atari and NFTs recently? Is there really that big of an overlap between Atari fans and crypto bros?

    While there were a few earlier devices that could save game data (the Famicom Data Recorder and FDS were mentioned earlier), the first accessory that I know of that saved your position in a game using solid state electronics was the ASCII Turbo File in 1986. It plugged into the Famicom and saved data from supported games to its own battery-backed RAM. It was compatible with games such as Castle Excellent (which also supported the Data Recorder for saving), some of the Wizardry games, and Downtown - Nekketsu Monogatari (japanese version of River City Random). https://en.m.wikipedia.org/wiki/Turbo_File_(ASCII)

    I guess I should have clarified that I was trying to get S-Video instead of composite from the start and wanted to use a standard S-Video cable for the output since my CRT supports it. The cable I was using at the time didn't output a picture for some reason so I wired chroma and luma to RCA plugs and plugged them into my TV's composite jack to see if I get anything from either of them. The picture of the TV was taken just after adding the trimmer and replacing the S-Video cable.

    Hi, I found this thread containing instructions on how to make a small S-Video board and I figured I'd try to make one for my 600XL for a summer project. However, I seem to be having some problems with the picture signal. When I test the S-Video, I get the results below for about a second and then my TV loses signal. Adjusting the trimmer and even using a different S-Video cable makes no difference. Below is how I built and installed the card. The orange wire is luma, blue is chroma, and the striped wire is ground. The board itself uses a 10uf 50v capacitor for chroma and outputs to an S-Video cable.

    I attempted to do this mod to get s-video from my NTSC 600xl and I think I'm missing something. I wired chroma and luma to two separate RCA cables to diagnose the problem. When I connect these cables to composite, I get no picture from luma and a dotty, scrolling, black with dots of white picture on chroma of which I can vaguely make out Star Raiders. The picture looks fine when I undue the mod and connect the computer through RF. Can someone please post a picture of this mod on a 600xl so I can cross-reference it with my own work?

    I'm actually in the southern U.S. I put "L-5" for my location as a joke for the Atari 2600 game "Encounter at L-5".

    I'm based in the US. I think the Brewing Academy board would be the closest to what I want, but it seems that it requires the interface board with the ps/2 and headphone jack. What I had in mind was that I was going to also mod my computer for s-video and route the video and audio to one cable.

    Hi, ever since I bought a donor board to repair my 600xl with, I've had a spare, perfectly good Pokey chip just lying around. I'm thinking of using it for a stereo mod, but I can't seem to find where to purchase a stereo pokey board. Does anyone know where I can get one?
  9. The Mr. Video
    Sorry to ask, but am I reading an Ebay description or War and Peace? A few sentences would have been enough!
  10. The Mr. Video
    You actually can get surround sound from the SNES, but it requires an audio amplifier that supports Dolby Surround. The amp reroutes out of phase audio from the stereo soundtrack to the rear speaker channel. I actually tried it myself a few days ago. It's not anything too amazing, but if you have the equipment, I'd say give it a try.

    I've seen the collision glitch happen when I used to play Kool Aid Man on 2600 Online. Does anyone know exactly why later revision TIAs cause the digits to be pushed together and make the game bug out?

    I borrowed a screw from my GBA to see if it would screw in and it did, so NGPC screws must be the same kind of screws used for the GBA except with a philips head instead of a triwing head.
  13. The Mr. Video
    That's what my screw is. I just need to know what size of screws I should look for.
  14. The Mr. Video
    The top of the outer screws do look like the top picture.

    Hi, my Neo Geo Pocket Color is in desperate need of extra screws. I'm down to one screw holding the casing together and I would like to know what kind of screws are used for the system so I can get some more.

    I've never been much of an RPG guy, but I've been wanting to play the fan translation for Live-A-Live for a while now, I just never could get around to it. The remake looks great so far, so maybe I'll finally take the plunge once it's released.

    Commodore woes are OVER! It's a bit of a cop out, but I bought a replacement board off ebay to put in the 1541 and now it works again. It may have taken me until now to view the SX-64 Christmas Demo, but better late than never.

    I keep forgetting to change my profile picture back.

    You should definitely try reflowing solder on the Gemini's cartridge port as the solder tends to crack on areas such as the joystick ports, power jack, and of course the cartridge slot. I've never owned or repaired a 4 switch Atari, so all I can suggest is to open it up, inspect the board, and reseat any socketed chips. Someone else with way more knowledge on 4 switch 2600s could probably go more in-depth on what might be causing the problem and how to fix it.
  20. The Mr. Video
    It's a tripleheader! Even though the cartridge has a torn end label and a bad case of acti-plaque, I couldn't resist not paying a small fortune for a great Genesis game. Also, is "AE" really the japanese term for "stingray" like Broderbund claims it is?

    While there are plenty of resources out there meant to get you up to speed on using an Atari 8-bit, one I can recommend is the Atari XL User's Handbook. It functions as a general guide on how to use Atari XL computers in particular as well other useful topics such as how to program in Atari Basic and how to use DOS 2.0 and DOS 3.0. It also has a handy basic reference guide in the back. As someone stated earlier in this post, Atari Mania has an archive of books as well as manuals and magazines covering the Atari 8-bit computers.

    My C64 woes continue now that my 1541 drive stopped working while I was replacing my breadbin's CIA chip. Why do Commodore stuff have to be so needy?

      Commodore did a lot of cost-cutting, likely extended into the (lower) quality of parts.

  23. The Mr. Video

    The good news is that I got the sockets soldered to the C64. The bad news is that swapping cia chips only makes the c64 not load from the disk drive, so I definitely need a new CIA chip. ?

  24. The Mr. Video

    FINALLY desoldered both CIA chips from my C64, and I've already decided I never want to do it again so I need to get some sockets.

      If a chip is removed for any reason, the #1 rule is a socket goes back in place first.

  25. The Mr. Video

    It's a sad day when your c64's CIA chip goes bad and it's directly soldered to the board.

      the c64 has a fairly reasonable board, but no one in human history has said " oh boy I can't wait to desolder a 40 pin dip package!"

    3. Stephen

      With a decent desoldering station (my Hakko 808 for example) - I can desolder (without damaging) a 40-pin DIP in under 60 seconds.  When I am doing my Ataris, even the notoriously junk XE line, I'll do a 40-pin DIP and the chip falls out under gravity without touching it after cleaning the last pin.  It's really easy to get a rhythm going.

      Kinda like a special-ed ASMR situation. Oddly relaxing.

       

      I was never able to get it under two minutes. But they do fall out with the last pin.
