Just cause the op has not seen a problem does not mean its fine. For 30 cents of parts everything can be within manufacturer spec.

Great project. Do you have a Github or somewhere that the PCB's and schematic are? Would love to rework the board and add level shifters.

I have given up for now. Might grab the original dev board used in the original article and do a rebuild. Has to do with something on the dev board I purchased. Anyway thanks for you help Al_Nafuur!

Thanks for that. just tested and just get the big SD displayed. If I hit he reset button on the dev board I get that same test menu list up again.

Hey guys. Wondering if you can help. Built a cart using a stm32f407vgt6 diymore dev board. I managed to get a menu but from what I have been told this is a test menu. It's not reading from my sdcard. Any ideas what could be the problem? Thanks Sent from my SM-G955F using Tapatalk

I took your advise and ordered a Sophia. Can't wait now. Would like to see how others have mounted the device

Thanks everyone for the comments. This has helped heaps. I contacted The Brewing Company but never received a reply so its great that andymanone managed to get in contact with them. I think I will go down the UAV route for now as its the cheapest and easiest to come by. If i hear back about the Sophia I would love to grab one of those also.

Thanks for that!! I wonder if the TBA's Ultimate Atari Video (UAV) av mod would work on a SECAM model.

Yes it has a 6 pin din connector. I have already made up a composite cable for it but just not happy with the quality. Do you have the rest of the SECAM schematic?

Hi Team, I managed to get a Atari 800XL from France recently. I live in Australia and all our equipment here supports all standards. I am disappointed with the quality of the output and was wondering if there is any AV/SVideo mod for the French models? There is not much information out there on these and was hoping there may be some French or European users here that know if any mods that can be performed. Thanks

Just started following this thread. Wondering if anyone has tried Zimmerman's firmware https://github.com/bozimmerman/Zimodem Its for a C64 but should work with Atari also.

I was advised here to move away from powering externally. Strange that I have one 2.8" screen and that works perfectly. just seems to be the 2.4" screen. Could it be something to do with the LCD and SDcard hardware on it? i might just reformat the sdcard and see if that makes any difference. Could be the sdcard being a ms too slow

Hey Team, I have made a few of these and had a bunch of 2.4" screens that came in a lot. I managed to find the right firmware to use to get them working. What i have found is that on a cold boot the Atari does not see the drive and i have to do a quick power cycle of the machine to get it to recognize. i suspect it is something to do with the sdcard not initializing fast enough on boot up. My system is a Pal 130XE and I am getting power from the SIO port. Wondering if there is any hack that can be done to the uno to get it to initialize faster is that is what the problem is. Thanks

That is exactly what I needed to know. When I get home I will try it out. Thank you!!!

Hello there. Probably a silly question. I purchased a STM32F407VGT6 board as per the guide. I have just connected it to my PC to upload the hex file but its not detecting in windows. Do I need to use a STM-Link programmer for this or should I be able to just use the STM-Utility to program when the dev board is connected VIA a USB cable. Just want to determine if my dev board is faulty or if I am doing something wrong. Thanks
