  2. #FujiNet is a complex beast, for sure. It has tons of firmware, and would need a full ESP32 emulation, or high level equivalents of everything in the firmware. This is infeasible, and @phaeron has admitted as much. But I was talking to @48kRAM tonight, and he posed a question: What if there could be a simple UDP bridge that bridged over SIO to a real FujiNet? This is possible, because the FujiNet can run entirely stand-alone, not connected to an Atari, only needing power. It could be placed into a mode where it would reflect the SIO traffic to UDP packets to the FujiNet and back. So while you would need a FujiNet device, they're only $65, and you wouldn't need a physical Atari to run it on. It would allow for software development to take place, very easily, and within the confines of emulation, where you have _EXCELLENT_ debugging facilities. @phaeron is the python device server stuff documented? Could it be used to prototype something for this? Thoughts? -Thom
  3. Hi everyone. I'm putting together vintage computer and console related items which I hope to sell. Please click below to see the current items I'm listing. Items For Sale I'll be adding more as I test, and package the items. Thanks, John
  4. While researching my documentary on the many types of Atari VCS hardware, clones, and add-on adapters to allow other systems to play Atari, I had to include the attempted cartridge adapters from Cardco and Protecto that were advertised in the early 80s, but of course ended up being vaporware.
  5. 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

  7. There is a new DIY through hole FujiNet hardware design that uses the espressif devkitc-ve board. It's basically a shield for the devkit board with all the needed bits for FujiNet. I'm happy to finally see someone else release hardware based on the completely open FujiNet design. https://github.com/djtersteegc/fujinet-devkit-shield
  8. Hello everyone! I picked up this device at a surplus electronic store, and I wanted to know if you folks might have more information on what it is, how to use it, etc.? I believe it is an EPROM programmer but I cannot find any info on it when I look it up or the associated company (Timely Technology). I wondered if it could be used to write to EPROM chips for creating homebrew cartridges for the 2600 but I'm not sure what else I would need to get it hooked to a modern computer. I think one of the cables is a parallel port but I'm not 100%. I'm hoping someone can point me in the right direction with this!

  13. 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!

  15. So a friend picked up a Vectrex with a few games recently while on vacation. Worked great when he tested it at the seller's house. Placed the system in his trunk, drove home from Florida (we're in Tennessee), and then tried playing with it again once he got home. Only this time, it wouldn't come up. When he turned the power knob, the only indication that it was getting power at all was a bit of static when adjusting the volume knob. That initially led me to believe that it was something to do with the vibration or possible jarring in the trunk on the ride home that might have caused it to stop working. So he gave it to me to take a go at fixing it since I have at least basic electronic repair skills. I did a bit of research and went through all the basic repairs: popped open the case, discharged the tube, pulled, polished, and reseated all the removable ICs, re-flowed the 4 power pins coming in from the power board to the logic board, cleaned the power pins, checked the voltages coming into the logic board (got all good readings of -5, +5, and -13 reading from the PCB), and just did some general cleanup of the 30 years of crud that had accumulated on the board and in the case. Still no dice. I wanted to see if the monitor was lighting up at all, so I turned off all the lights in my office, then fired up the Vectrex. Sure enough, after turning it on and waiting 10-15 seconds, I gradually saw a little white dot rising from the bottom of the screen and coming to a stop a bit northeast of center. When I turned off the power, the white dot illuminated a bit brighter for a split-second, then immediately went away (rather than slowly fading out like my working Vectrex does at power-down). That behavior makes me think it's most likely to be a capacitor problem, but I wanted to check here with the experts before making any assumptions and dropping money on a cap kit that may be either unnecessary or futile. Of course, I don't know if that would necessarily explain why the BIOS (or whatever) doesn't still fire up and play the little musical ditty on startup. My own uninformed theory is that, even though the voltages are reading good, it's possible that bad capacitors on the power board are not supplying the amperage that the logic board or tube needs. Ok! Now that my own highly-amateur insights are done with: Any advice on how to proceed? Other places to check for voltages that might help? Maybe there are pics I could take and share that would assist with the diagnosis? I'm determined to resuscitate this glorious little black box, but I need some nudges in what is presumed to be the right direction. Thanks in advance!
  16. 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.
  17. Mean Time Before Failure - It's starting to look like this is beginning to effect more and more P-Box power supplies. Preemptive Maintenance - Fixing the situation before it destroys something else more expensive with it's failure or, puts one out of service. Plug & Play - Designed so even the least technical people in the consumer market will feel comfortable installing it, ensuring more sales. Limited Targeted Market - Niche markets, usually have test markets or single runs of a moderate size to keep costs down. I'm thinking it may be time for "someone out there" to consider a viable Plug & Play replacement for the P-Box power supply. 1 - Could the cost be reasonable? (How much are you willing to spend for an easy replacement to protect your equipment) 2 - Could it be a direct replacement, not requiring any other modifications from the customer. 3 - Could there be "an extra" on the board as a further inducement to purchase? (Example: USB power port)
  18. 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.
  19. 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.
  20. 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?
  21. 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
