  1. Atari Systems

    1. Atari General

      A general discussion for Atari-related topics that aren't covered by a specific Atari console or computer forum.

    2. Atari 2600

      The Atari 2600 is the system that started it all for Atari, and is by far the most popular classic gaming console. This forum covers all 2600 systems produced by Atari, as well as 2600-compatible consoles produced by third-parties.

    3. Atari 5200

      The Atari 5200 was Atari's second cartridge-based game console. Based on the Atari 8-bit computer line and labeled the "SuperSystem", the 5200 was Atari's answer to growing competition in a market they were losing control over.

    4. Atari 7800

      The Atari 7800 ProSystem is a contemporary of the Nintendo Entertainment System and the Sega Master System. Based on extensive feedback from Atari customers, the 7800 features a streamlined design, backward compatibility with the 2600, a powerful graphics processor, and simplified controllers.

    5. Atari Lynx

      Lynx was Atari's first portable game system, and world's first color handheld. It was designed by Epyx and the engineers who created the Amiga. Ahead of its time, the Lynx sported a backlit color screen, stereo sound (in model 2) and an impressive range of games. Check out our rarity guide or explore many games listed on Atari Gamer.


    6. Atari Jaguar

      Atari's last game console, the Atari Jaguar represented a huge leap in technology from previous offerings. Featuring a 64-bit architecture, the Jaguar had great potential, but its power was difficult to tap. Even then, many great games were released and the Jaguar has an avid fan base today.

    7. Atari VCS

      Discussion forum for the new Atari VCS console.

    8. Dedicated Systems

      Before Atari produced the famous 2600, they created many standalone consoles such as Pong, Speedway, and Stunt Cycle. Recently, Atari has been creating new dedicated consoles, such as the Atari Flashback.

    9. Atari 8-Bit Computers

      Atari's original 8-bit computer line, featuring the Atari 400, 800, XL, and XE series of computers. Powerful and well-engineered, the Atari 8-bit computers are still popular with fans today!

    10. Atari ST/TT/Falcon Computers

      Atari's next generation computer line, the Atari ST computers were based on the Motorola 68000 series chips, the same as the Macintosh at the time. The ST would also be followed by the TT and Falcon.

    11. Atari Portfolio

      The Atari Portfolio is a palmtop, IBM PC-compatible portable computer released by Atari in 1989, the world's first palmtop computer!

    • The game looks really good. Nice review. Thank you.
    • As an extreme aside, searching for Robert Zdybel pulls up this interesting little page: https://everything2.com/title/Rob+Zdybel    
    • I'm not optimistic that the situation will change with the Duo's built-in 2.4g 8BitDo receiver. I have a feeling that the Pocket dock situation will carry over, requiring Duo specific controller firmware to be flashed to 2.4 8BitDo controllers.   That said, they just added Pocket compatibility for the wired USB TG16/PC Engine/CoreGrafx Mini gamepad. Seems like a great sign that the Duo will have similar support, which perhaps means that we'll at least be able to just plug in the 8BitDo's own 2.4g USB receiver into one of the Duo's USB controller ports and utilize the controller in its stock form without having to flash exclusive firmware to it that breaks compatibility with everything else.   Using an external receiver isn't as seamless as it should be, but if it happens it at least will make using the same controller on a mix of non-Analogue systems and the Analogue Duo actually practical (since who wants to repeatedly reflash controller firmware).
    • There was a hash for 7800 NTSC carts and an encryption with obfuscation for the Lynx carts. This was to prevent creation of unauthorized carts. These keys are known today.   The check sum is just for checking that the transmission from the dumper to the CPU is correct. But there is dozens of ways to calculate it. We have an idea how it works but the small details are not known.
    • I'd be interested but I wonder what this Vectrex highscore club would offer its members and what it would be good for. Could you explain a bit or point to an example?
    • @abbotkinneydude is going to be drooling over this.   Seems the German subsidiary of Nakamichi was selling this cool setup in the mid-eighties. Apart from a short mention in another German mag, Happy Computer, I couldn't find any other article or review. Anybody familiar with this package?  
    • First, you are implying that there was no short before you replaced capacitors.  Was the 2600 working before being recapped?  Did you test for shorts before recapping?  What method did you use to determine that there was a short?  Did you connect the 2600 to power before testing for shorts after recapping?  Assuming there were no shorts before you worked on the 2600, did you test the new capacitors before installing them?   Second, your image quality could be acceptable for fault finding, but you are hiding part of the bottom of the board that you claim has a fault.  We need to see the whole thing, even if you don't think you did anything there that could cause a problem.
    • It's not address line reflections, it's open bus data. The 130XE and 400 do this as well, but what's special about the 800 is that it has two data buses with buffers in between, so different address ranges only affect one or both of the data buses. In particular, the CPU, ANTIC, GTIA and RAM is isolated from I/O, including system ROMs, cartridges, GTIA, and POKEY.   What happens when BASIC runs PEEK(54528) for instance, is that it executes an LDA ($D4),Y instruction, which fetches the two instruction bytes from the cartridge from the I/O bus through the buffers ($B1 and $D4), then the indirect address of 54528 ($D500) from RAM over the local bus only, then reads $D500 from the I/O bus through the buffers. Nothing responds to the $D500 request, so open bus data is returned. But in the 800's case, this is from the I/O bus, which has never seen the indirect address reads from RAM and still holds the last I/O bus read from the cartridge. The result is that an 800 shows a mix of mostly 212 ($D4) and 0 (if ANTIC DMAs in between), while a 130XE shows a mix of 213 ($D5) and 0. This is emulated in Altirra: the 800XL system mode uses pull-ups on the data bus, the 130XE system mode uses a floating data bus, and the 800 uses split data buses when enabled (System > Computer > Memory > Enable floating I/O bus).   In terms of using this to identify the system, though, there are a few problems: The behavior changes depending on whether the test code is running from cartridge or RAM, since that changes whether instruction bytes are pulled across the I/O bus or not. You have to know what the behavior should be for the system, which means detecting the system type -- which is not simple in all pertinent cases. This includes distinguishing between an 800 and a 400 expanded to 48K, or IIRC, a 65XE and an 800XE. Add-ons can potentially change this behavior, including an Incognito in an 800, or a motherboard replacement. Other than a hardware test or a diagnostic tool, there isn't much reason to test for open bus behavior since there's no benefit to code depending on it. Most of the cases that we have seen were unintentional bugs that resulted in weird behavior on 130XEs. You could probably use it as part of some "real hardware" check, sure. But unless you're a purist to the extent of believing only in booting software off a floppy disk or cartridge with a burned EPROM, chances are many of the potential users of your software would be using at least one component somewhere that isn't completely faithful to the hardware as it existed in the early 80s and could fail such a check.
