  1. Hi everyone. I sold this Atari 400 with 410 recorder on eBay with no only a power cable, no plug attached. The buyer purchased an additionally required cable to hook up to a screen and when he turned on this appears on the screen. The eBayer 100% knows what they are doing and said if I partially refund then he will get it fixed. He only paid £50 for it. Is this a case of cleaning the inside with some alcohol and putting it back together? System hasn’t been used in...25 years. Many thanks for your help.
  2. So a long while ago I had a bright idea on a "captain's chair" 'controller' for playing Star Raiders on the 8-bit / 5200. My thought is a joystick on one arm of the chair (e.g. on the right, for right-handed folks), with a thumb trigger on top, or index finger trigger on the front, so it can be controlled entirely with one hand. On the other side, there'd be a keypad controller (like used by the 2600 version of the game), offering the various toggle controls: front view (F) aft view (A) long range view (L) galactic map (G) attack computer (C) targeting computer (T) target selector (M) shields (S) hyperwarp (H) pause (P) That's 10 keys, so totally doable with a 12-button keyboard controller, connected to the second controller port. Finally, on that same side (e.g., left, for right-handed users) would be an analog throttle, like you see in a boat. Fully forward (towards the TV) would be "twin-ion engine" at full-speed (9), and fully back (toward the player) would be full-stop (0). This would be connected to the paddle input of controller port 1, alongside the main digital joystick input (if I'm reading things right, it looks like the POT stuff is used by keyboard controllers). Obviously, a hacked version of Star Raiders would be required for this to work (read paddle for engine control, read keyboard controller for other keyboard control). It'd be a pretty cool set-up, though, don't you think? Sadly, I don't have the skill to do either the hardware, or the ROM hacking. 😛
  3. Hi folks, I am new at AtariAge. Months ago, I've got an AV-modded european Atari 2600 Jr. (Rev. F board) in a great condition for cheap. However, here at my country (Brazil), PAL-B compatible TV sets are rare to find. The closest color system that is supported by most TVs is PAL-N (PAL variation used in Argentina and a few more countries in South America). I tried to replace the 4.433618 MHz XTAL with a 3.582056 MHz one, but that gave me no colors in any PAL-N compatible set. Also tried to replace the 3.546894 MHz one with a second 3.582056 MHz XTAL, but still gave me nothing but B&W picture. Is there something I can do to make this console output PAL-N? Both systems are 50 Hz and have the same resolution, so it should work somehow. Thanks a lot!

  5. Hi 99ers, I have found a "strange" module, maybe somebody knows something about ? Thanks for all infos Ralf
  6. Truths: the FinalGROM has a massive amount of storage space. the TIPI also has a massive amount of storage space. So the question is, on which device you store most of your games? While the poll is anonymous, please feel free to tell us WHY you have one preference over another.
  7. I'm starting this thread as a means to hopefully promote some F18A development, answer specific questions about programming the F18A, and finally as place to look for links to updated documentation and eventually firmware updates. This first post will always have the latest documents and updates attached, so there is no need to go digging through the thread to find the most recent information. I also hope it will contain questions, answers, and code examples. I would like to keep this thread technical and on-topic, so if you have other general F18A questions or comments, please start a new thread or use the other existing F18A thread. * Documentation: On-going. This is something I hope to complete, but until then Rasmus has collected many of the F18A programming posts from the forum and created PDF of them (thank you Rasmus!) See the files attached to this thread, and please ask F18A technical questions in this thread. The main F18A webpage (http://codehackcreate.com/archives/30) has the main feature list, as well as an initial post to getting started with programming the F18A. As I add documentation, I will post it on the website first, then make an update here to let anyone interested know there is something new. * Register Use Spreadsheet: Libre Office / Open Office .ods format. This is the primary spreadsheet I used while developing the F18A, and all functionality was documented in the spreadsheet first, then converted into HDL. That means the spreadsheet is always up to date with respect to the F18A's functionality. While some of the F18A's features require more documentation to use, much of the functionality is very self explanatory and can be used just by looking at the spreadsheet and reading the notes. For example, it does not take much to guessing to figure out what the "horizontal scroll register" does. ************* COMPATIBILITY ************* Pin-compatible replacement for the TMS9918A, 9928, 9929, and TMS9118 Video Data Processors. The F18A has been tested in the following systems: TI-99/4A Home Computer ColecoVison Game Console* ColecoVision ADAM Computer# Toshiba HX-10 MSX1 Computer Toshiba Pasopia-IQ MSX1 Computer JVC Victor HC-7 MSX1 Computer Yamaha CX5M MSX1 [email protected] SpectraVideo 328 Computer*@ Tomy Tutor Computer*@ SEGA SG-1000 Game Console SEGA SC-1000II (replaced a TMS9118 VDP) Telegames Personal Arcade Powertran Cortex Computer * Note1: These systems are known to have the original VDP soldered directly to the system circuit board and will require desoldering and a socket installed. # Note2: The ADAM computer requires an "offset board" to keep the F18A inside the main PCB outline. This is an available option when ordering and F18A. @ Note3: These systems are known to require USR4 jumper removed because the main system uses the CPUCLK output from the VDP as the main system clock. ************************ F18A FIRMWARE Change Log ************************ F18A V1.9 Dec 31, 2018 (CRC: 147A) * Prepare for open source release. * Split up the original "core" to create a top-module for the stand-alone F18A, and a "main core" that can be used as part of a larger SoC. * Fixed the VGA horizontal timing error caused by treating the pixel time as 40ns instead of 39.68ns. Because events were being counted in "pixels", this caused the horizontal sync pulse to be slightly off, and the overall line time to be 32us instead of 31.746us. This error meant each line was around 6.4 pixels too long, and pushed the total frame rate to 59.2Hz. This error was enough to cause games to fail (Pole Position on the 99/4A), and some monitors to not sync properly when run through video converters. The timing error also caused many problems for the PAL ColecoVision. * Removed sprite-linking. This was an unused feature and helped free up FPGA resources to allow the core to better fit in the Spartan-3E 250K. * Removed programmable GROMCLK divisor. Unused feature, free up resources. * Register mode and cd_i inputs to CPU component. V1.8 - Aug 24, 2016 (CRC: F981) * Fixed sprite collision bug where sprite collisions were being incorrectly detected outside of the active display, after line 191 or 239 depending on the line mode. * Added hybrid VR write restriction to mask VR writes to three-bits when the F18A is locked, like the real 9918A does. However, if mode bit M4 is set (80-columns), writes to VRs over VR7 are *ignored* instead of masked to three-bits. This allows various 9938 programs to work (or continue to work), as well as continue to support TurboForth that writes to VRs 0..15 to set up 80-columns (if straight masking was used, VRs 8..15 would over-write VR 0..7). V1.7 - Jan 1, 2016 (CRC: A3B5) * Fixed Bitmap-Layer (BML) display bug * Fixed GPU's PIX instruction to properly calculate BML addresses * Added power-on graphic that shows the current firmware version V1.6 - Apr 26, 2015 (CRC: 40CC) * Removed fixed tile functionality * Removed border scroll limit functionality * Removed banner functionality * Removed host-side 32-bit counter * Removed host-side 32-bit RNG * Removed GPU 32-bit counter * Removed GPU 32-bit RNG * Removed the sprite "disable value" (>F8) in the sprite Y-location when ROW30 is enabled. * Added second tile layer with its own NTBA, h/v page sizes, and h/v scroll regs * Added ECM2/3 pattern table size selections for tiles and sprites. * Added host-side segmented counter with 10ns accuracy. * Added configurable HSYNC and VSYNC GPU triggers. * Added fat-pixel (2x1) with 16-color support to the bitmap layer (BML). * Added 1x1 page scroll support for T40 and T80 modes. * Added option to reset most VDP registers to their power-on values. * Added option to disable Tile Layer 1, which includes GM1, GM2, MCM, T40, and T80. Sprites, the BML, and TL2 are still active and can be enabled/disabled independently. * Added option to allow attribute byte to be fg/bg color select in T40 and T80. * Added per-position tile attribute support. * Added DMA capability to the GPU: 8xx0 - MSB src 8xx1 - LSB src 8xx2 - MSB dst 8xx3 - LSB dst 8xx4 - width 8xx5 - height 8xx6 - stride 8xx7 - 0..5 | !INC/DEC | !COPY/FILL 8xx8 - trigger FILL (active high) will read a single byte at the src address and fill the destination with that byte. src, dst, width, height, and stride are copied to dedicated counters when the DMA is triggered, thus the original values remain unchanged. * Added USR3 jumper to control GROMCLK/CPUCLK output on pin37 to provide support for 9128/29 * Added USR2 jumper to disable/enable simulated scan lines (every other VGA scan line has its color reduced by 50%.) Also controllable via a new VDP register bit. * Added a 5th sprite reporting option instead of reporting the max-sprite, which on the F18A might be different than the original VDP because all 32 sprites can be on a single scan line. * Added a new register (VR51) to limit the maximum sprite processed. This has nothing to do with the number of sprites that can be visible on a scan line, which is controlled by a separate register (VR30). This register is always active and can be used instead of the >D0 byte in the sprite Y-location, and is the only way to limit sprite processing early when ROW30 is enabled. * Changed the GPU interlock so that polling the VDP status register will not cause the GPU to pause. This should greatly increase GPU performance during heavy VDP interrupt polling. * Fixed T80 NTBA two LSbit problem. They are ignored (set to "00") when the F18A is locked to provide compatibility with the 9938 and avoid problem with software that set the two LSbits of the NTBA to other than "11" as the 9938 documentation specifies they should be. This limits the T80 name table to 4K boundaries. When the F18A is unlocked, all 4-bits of the NTBA are used and the T80 name table can be located on 1K boundaries. * Fixed the 5th number update during a scan line. As long as the 5S flag is zero, the 5th number register follows the sprite scanning sequence. Seems to be a transparent latch that follows the input (current sprite being scanned) until latched by the 5S flag. If the status register is being polled and 5S is reset mid frame, then the 5th number begins following the scanned sprites again. This bug is known to have affected Miner49er on the 99/4A. V1.5 - July 2013 Not really a *bug* fix since the problem it corrects exists on the real 9918A, and only has to do with sporadic collision bit reporting during heavy polling of the original 9918A VDP status register. This was discovered while Rasmus was writing Titanium. The 9918A was not designed to have its status register polled which is why it provides an interrupt output. I don't think the original 9918A designers took the hazard into consideration, but I decided to make this correction because it is what the original designers would have done given their preference (and I asked Karl Guttag about it). Thus, the F18A implements what you would consider the "expected behavior", and will work as expected where the original 9918A might not. I did not make this decision lightly. V1.4 - April 2013 Fixed the sprite collision bug and a GPU bug with the divide circuit. The sprite bug is mostly affected by XB when a program uses CALL COINC(ALL). Most assembly games probably don't rely on the collision bit alone for sprites and perform coordinate testing, which is most likely why the bug slipped through all the testing (and I tested with a *lot* of games on a lot of platforms). V1.3 - July 2012 Original release firmware. ******** UPDATING ******** The In-System firmware update is available for 99/4A users. I am very thankful to Rasums and Tursi for their help in making this possible. You can download the F18AUpdate_vXX.zip file below. Detailed instructions are available on my website here: http://codehackcreate.com/archives/418 Alternatively you can update your F18A in any system via a JTAG programming cable. You can purchase a JTAG programming cable for about $59 USD from Digilent: JTAG HS3 programming cable/ This is very inexpensive for a JTAG cable (my Xilinx-brand cable was over $250!), and Digilent makes quality gear. You also need the Xilinx ISE-Webpack tools: http://www.xilinx.com/support/download/index.htm This is a free download from Xilinx, but it is BIG! About 6GB the last time I checked. There is a smaller download that contains just the programming tools called "Lab Tools" and is only about 1G. I'm still looking for a smaller / simpler solution. You will have to create an account (which is free). The primary program you need is called IMPACT and is used to program the FPGA and SPI-flash. Once you get the tools installed, download and unzip the f18a_250k_vXX.zip file. In the zip file you will find the MCS file: f18a_250k_vXX.mcs The .mcs file is used to update the SPI-flash ROM attached to the FPGA. Here are the quick instructions. The term "system" means your 99/4A, ColecoVision, MSX, etc., and "PC" means the modern personal computer you are running the Xilinx tools on. 0. Make sure your system is powered OFF to begin 1. Open your system to get physical access to the F18A 2. Plug the JTAG programmer in to your PC (via USB) and the F18A (via JTAG) 3. Power ON your system 4. Launch the Xilinx IMPACT tool 5. Double-click on "Boundary Scan", then right-click in the main area and select "initialize chain" 6. The FPGA should be detected and show up in the big area. A window will open with device properties, just click "ok" 7. Above the FPGA icon should be a dotted line with "SPI/BPI ?" in it. Right-click on that box and select "Add SPI/BPI Flash..." 8. Navigate to the f18a_250k_vXX.mcs file you extracted from the .zip file and choose "Open" 9. Select "SPI PROM" and "M25P80" from the two drop-down selections and click "OK" 10. The box above the FPGA should now say "FLASH" in it. Right-click the box and select "Program" Once the programming is finished, cycle power on your system and make sure it comes up. ******** Examples ******** Included in the zip file is a demos disk that shows many of the enhanced features of the F18A. The source for all the programs are included. I did not write these programs and I am very thankful to Rasmus and Tursi for contributing them. rasmus_scroll.zip F18A documentation.pdf f18a_register_use.zip F18A_V19.zip
  8. Hello, If anyone one has or has had any experience with the xl eprom burner (the one that plugs into the cart slot of an xl/xe) and can spare a few posts/time to help me out with a couple questions please reply or send a private message. It would be much appreciated!
  9. Probably a simple question, but I am having a hard time verifying my assumptions. I was wondering if this kit from Console 5 could be used to replace the bios chip in the base console, if the CD bios is replaced with base console bios? http://console5.com/store/atari-jaguar-cd-encryption-bypass-bios-kit.html Here is the link to the Console 5 wiki where they list the part number for the chip in the kit http://console5.com/wiki/Atari_Jaguar_CD I am trying to resurrect a console, and my technician (40+ years as a electronics technician and still practicing) says that the usual problems that Jaguar consoles run into aren't the issue in this case, after testing the usual suspects that are listed online. he suspects the bios may have been corrupted somehow at some point, after monitoring the boot process on an oscilloscope (this is all voodoo magic to me). Each time he boots the system with a game, the boot process is inconsistent. He has asked me to the purchase the parts necessary to test a working bios in the system (He is troubleshooting this as a favor to me, because he hasn't worked on any Atari product since the 90's, and is mentoring me at the same time. He expects me to do a bit of the leg work for the free work and instruction he is providing). First he just wants to add the socket so he doesn't have to keep soldering/unsoldering things, then he wants to try pulling the bios out of one of my working consoles, and test it in the non-working one first, to determine if the bios is really the problem. I assume that the socket in the kit will work fine, because of the same pin count and package design. But I want to make sure that the chip that comes in the kit can be used with the Jaguar bios image. Also, are there any other things I should be aware of when it comes to the bios? It seems like I have read something while meandering on the webs that there are different versions of the jaguar bios for the base console. Is this something to consider? Just for fun, here is the Console 5 wiki for the base jaguar console. Unfortunately they don't list an equivalent part to replace the bios. http://console5.com/wiki/Atari_Jaguar Thanks in advance for any advice that is given.
  10. Hi, recently bought a 1050 where a Happy-Clone from IRATA (Berlin Germany) is installed. It also runs flawlessly, only it has a few more contact surfaces (see picture), and I can not find ANYWHERE documents. So I wanted to know if any of you still have information about it (Schematics, Switches like "Speed on/off" a.s.o.) It is also recognized by Happy-Tooldisk 1 as Happy, and the tests run completely, except for ROM positive - But I had the same with another Happy-Clone that it hooked right there, which is also logical, because the values of the EPROM are not 100% those of the origin. I just want to know what else I can do with it, that is, what else I can connect and above all where on the PINS. And important : What features are included? tya for reading 🙂
  11. http://retroconsoles.wikia.com Hello everyone, I'm the administrator of Retro Consoles Wiki (there I go by ITEM-3), a brand new website whose goal is to collect all the scattered information for repairs and mods for all video game consoles, especially older consoles. This includes high-quality pictures of every revision of each console's motherboard, identification of the chips, and links to their documentation. Related information like controllers, accessories, flashcarts, console clones, and general tips for working with electronics will eventually be a part of it. The site is just over a week old and has mostly been an effort on 4chan's /vr/ board (thread: http://boards.4chan.org/vr/res/694016), and so there isn't much content yet, but it is an ongoing project, and more content is being added everyday. It's hosted on Wikia for now, but I will move the site to paid hosting if more people start using it. Here are a couple examples of the types of pages and guides that are currently on the site: Sega Genesis motherboard info: http://retroconsoles.wikia.com/wiki/Sega_Genesis_Hardware 3DO FZ-10 Repair: http://retroconsoles.wikia.com/wiki/3DO_FZ-10_Repair_-_Lubricate_the_Laser_Sled I'm here to spread the word about the wiki and see if anyone would like to contribute or make a request for specific content. If you have a complicated issue with a console that you have not been able to repair, I encourage you to create a page detailing the problem. I'd like to hear any suggestions you might have for the site as well. I hope to see you all there!
  12. Hi all, As of today, I have put all files related to my snes2joy project on github. https://github.com/ivop/snes2joy It contains: * design documents * hardware schematic * gerber files * firmware source code and pre-compiled .hex file * native software to test, incl. source * step by step build photos * freecad and .obj files of 3D printable enclosure Everything is free to use (0-Clause BSD License), so if anybody wants to make a batch of them and sell them, be my guest. Would be nice if you send me one though But no obligations of course. That's what 0BSD means. Regards, Ivo Edit: to clarify, this means I won't be doing a run myself.

  16. In my effort to provide documentation for lynx, I've started a new task : "vectorisation" of the Atari Lynx Schematics. I've done it with KiCAD. The schematics are based on the 4 part of Atari Lynx Hardware Schematics This is not the "final" version. Some parts were hard to read/understand. If you see any mistake, please feel free to report it. Schematics v0.1.pdf
  17. OK, I didn't know if I should post this here or in Hardware, so I just put it here. I just got a 2600 Jr. today and it has a few issues. When you first turn it on, with any game or the Harmony cart, it takes probably 10 seconds before the picture shows up on the TV. When you put a Battlezone cart in and turn it on, it takes a few seconds, then you get the radar and some other random bits of the picture kind of jumping around the screen, then it will show up correctly, but with a very dim picture. In a couple of seconds, the picture brightens up and the colors are all good. If Demons to Diamonds is inserted, same wait time on start-up, but the color and brightness are good. Now, here's the big problem. When you hit reset to start Demons to Diamonds, it goes from color to Black and White. Unplugging the rca cable from the back of the console and then slowly putting it back, will allow you to see a split second of color before it goes B&W again. The same thing happens using the Demons and Diamonds .bin on the Harmony Encore. Also, With the Harmony, if you switch it off, while it's B&W and then switch it right back on, the Harmony menu is in B&W. Switching it off and on again, results in color. The Jr. isn't modded and an inspection of the board showed no bad solder joints or leaky caps. The Serial is A1781245617 The board is CO21503 Revision C On most games, it looks great, the colors and the picture are better than my AV modded Vader and 7800, other than the lack of a picture for a few seconds when you turn it on. Demons to Diamonds is the only game I've found so far that triggers the B&W issue, but I feel like that's a sign of something needing repair. So, does anyone have an answer as to what's wrong with it?
  18. I used TI Extended BASIC and 32K RAM expansion to write games and create music in the 1980s, and I'm trying to easily resurrect this content 35 years later. There are a variety of emulators and gizmos like the CatWeasel, but before I go too far, I'm wondering if there is a setup that can handle all these requirements: - Ability to read original 5-1/4" disks - TI Extended BASIC required - 32K RAM exapansion required - Games include custom "data" (strings of custom music and graphics) which must be periodically loaded during gameplay... not just code...this must be accessed using the "INPUT" (with files) command I'm trying to decide upon the right approach: 1. Repair or replace my original hardware and get it to run it on the original platform 2. Try to build a conversion / emulator system and bring these files into the 21st century 3. Find someone with existing conversion capabilities who might be willing to help I assume someone could help a software restoration newbie like me navigate the technical gotchas? The content is mainly text parser adventure games (rather goofy ones at that) and music and graphic utilities I authored myself. Thanks for all sage advice!
  19. Asking on behalf of a friend: Out of curiosity, I was wondering if there are any expansions for the Atari 800, much in the vein of the expansions we have for the Atari XL/XE computers (RAM expansion, etc.) The Atari 800 maxes out officially at 48K RAM, which isn't enough for most of the homebrew games and such that target 64K+ RAM systems. I remember reading a long time back about some RAM expansions and such that do work on the Atari 800, but it's been ages and I'm wondering if most of that information is still relevant or not. One I remember reading about was the Incognito card (?), which gave the 800 a nice RAM boost. I *think* that was the name of it? (see what I mean by it's been ages? ) Anywho, can anyone point me to some good expansions that target the good old 800 computer that may still be available for purchase somewhere? I don't need anything like a SIO2SD or an Ultimate Cart; those are handled already.
  20. go through this sellers list to find some interesting atari st stuff, seems to be listing more of it as well. eBay Seller: regalservice
  21. Trying to find more information and photos about the line of telephones Atari was working on in the early 1980s. It's fascinating stuff, but Atari Museum has very little information. Does anyone know where the prototypes have gone (thinking the trash, but hoping otherwise)? Are there more, higher quality photos? Did the kiosk ever make it out of the Atari offices? Thanks all!
  22. So I have a CX2600 model that has some issues with a controller port. The left port always registers the button as being constantly pressed or not pressed at all. The joystick still works fine. I've tried multiple controllers and none of them work in the left but they all function in the right. I was wondering if anyone could help me diagnose the issue and potentially find a solution.
