  1. Thank you, swapping sounds like the best approach. I will give it a go and follow up.
  2. i replaced it all with good working ram from another computer. and the computer behaved the same. So I ruled out ram . I have the ROM file for the Math Pac, I just need to find the rom files for A103 and A104 Cheers.
  3. Ram was tested, and all is good with ram. Had to edit this, obviously the Basic ROM is in the Basic cart, (not sure what I was thinking) I have several basic cartridges, and they work fine in my other Atari's so I don't think it's the basic cart that is the issue. works fine in my Atari 800 with no problems. Here are the currently installed system roms and math pack.
  4. Thank you for the information. it's very helpful, I will try and replace all three roms with 2764's on adapter boards, as I am not sure which one might have a bad section, and see if that helps. wondering if anyone has a link handy for the rom files? I can certainly wade through google results, but if anyone has them handy, that would be nice. cheers and thanks again.
  5. Hi there, I have an atari 400 that i recently received, which seems to play game carts totally fine. And if I boot it with no cart, the notepad app runs fine. However when starting up with a basic cartridge, it locks up after displaying ready on the screen. If I remove the the Math Pack Rom in A105, it Does the same thing, locks up after printing Ready on the screen. If I remove either of the other two roms, i just get a black screen. A couple of questions if I may: 1) is the math pac rom required for regular basic? will the computer function without it normally? 2) seems the Math Pac is a 2K Rom marked C012399B-03 in the A105 chip socket, what are the rom functions for A103 and A104? Cheers. Any hints would be great. Thanks folks.
  6. the SDrive automatically loads the menu program, and the Atari boots to that, i use the menu program to load all 4 disk drive slots, browsing through the files on the TV/monitor. Then i press the reset and it boots from the image I selected for Drive 0. I put the disk images on the SD card from my windows PC, i load up the sd card, then put it in the headless Sdrive. (I hope I understood the question correctly) Cheers. Just a thanks to the guys developing this, another thing to keep us busy Cheers guys.
  7. I created an SDRIVE, with no display and only one button, a reset. it loads the menu and I use the keyboard to select a disk image on screen. If I want to select a different disk image to boot from I reset the arduino so all 4 of my disk selections are dropped and I can reload them not sure if this is helpful, but it does seem to work ok :).
  8. Thanks for the link :). Yeah your right, I would have to make it accessible, to take advantage of the updates as they come. Could it be reflashed via bluetooth? I think the ESP32 has bluetooth built in? (one would still require access to the FLash button though so perhaps a mute point. ...) or just keep the 800xl lid unscrewed so to speak with the interface taped to the inside cover... I really need to give this all more thought. either way I'm excited, and I will be purchasing at least two of the final product when they are ready. Cheers.
  9. I love this project, you guys are doing an awesome thing. I've ordered a couple of ESP32 Dev boards, and looking forward to building an internal fujinet, I think. I currently have a couple of the standard ESP8266 boards, but I think i want to use the ESP32 instead. keep up the good work folks, I will be happy to post pics of my install and any questions or issues along the way. Which brings me to my first question, is it ok to simply solder to the required pins of the SIO connector on the motherboard (using the current schematic, not directly to the ESP32, sorry if that was not clear), so as to avoid having to build an enclosure, and figure out physical connection issues (excellent details on DIY here, but I'm still hoping to just stick it to the inside of the top portion of the case, outside of the RF shield. at any rate once again folks, this is awesome. Also quick note, I listened to "Antic, the Atari 8bit Podcast Episode 63" that has a great interview with Thom. excellent excellent information in that interview.
  10. So the 3 I ordered from bang good came, but were not the same as the previous two, even though it’s the same link. But the github had updated files for it https://github.com/kbr-net/sdrive-max/releases/download/v1.2b3/sdrive-max-v12b3.zip
  11. So I built a little headless SDrive Max (i temperarily connected an LCD to get bast the touch screen calibration, so not it boots to D0 and the sdrivemax.atr file, so I have an on screen display) My home made unit uses the 7407 chip along with the two resisters...it's using a little SD board with level translaters built in. I was thinking it might be nice to also have an internal wifi device as well, I'm not not sure how to connect to internal devices? is there a trick to connecting two devices to the SIO bus? I have to admit I am not familiar with what is involved with the daisy chainging. Or do I just hook up everything to 4,3,5,7,10 for each device? No display on my Sdrive max, so very little current draw... and the ESP01 does not draw much either... any clues on connecting both internally at the same time? Cheers.
  12. I ordered the proper 2.8” tft and came up right away, I ordered 5 in total, first 2 then 3 more once I know they were good with the ili9341 driver. Cheers. https://banggood.app.link/O7OmjwNo0Z
  13. yup that driver worked for me and I have the same display. I'm going to take one of the available 3d printable cases, and adjust the window for the 2.4" display. if I succeed without too much frustation, i will post the result.
  14. ok thank you for taking the time to respond. very much appreciated. Cheers.
