lanceroo Posted June 1, 2021 Share Posted June 1, 2021 I’m sure you’re design was solid - not criticizing it or you- just looking for some help without me needing to buy more things to troubleshoot. Almost any Atari owner with an old 800 ( that works as is) would be surprised to find that because of some out of tolerance component in their machine it would cause this problem. I tried 2 machines. I’m sure there are others out there. I have sent my board back - they have offered to test it - I hope they find nothing wrong.

Faicuai Posted June 2, 2021 Author Share Posted June 2, 2021 3 hours ago, lanceroo said: I tried 2 machines. After you tried multiple CPU-boards and finally another 800 host, it seems clear to me that the prime suspect here is your Sophia-2 board (I would be really surprised if there is another source of the problem). I have multiple NTSc MoBOs (Rev9 and RevA), with and without Incognito, and both CPU-board types, and my Sophia-2 unit worked in all of them, when I originally tested prior to final install. Your original vendor should be able to reproduce the problem or (at a minimum) have the appropriate resources to test well your Sophia board. Cheers!

Simius Posted June 2, 2021 Share Posted June 2, 2021 I think also many liver owners (that work as is) would be surprised to find that because of some out of tolerance it would cause ailments after drinking. Not always "it work as is" means "completely healthy".

eightbit Posted November 5 Share Posted November 5 Old thread I know, but this is linked from the current Brewing Academy purchase page for the Sofia 2, and I wanted to thank you for the guide! Install was quite simple and the video output is incredible on my 800. I should have done this a long time ago! 2 Quote Link to comment https://forums.atariage.com/topic/317398-atari-800-sophia-2-install-letting-antic-and-gtia-be-the-best-they-can-be/page/2/#findComment-5560635 Share on other sites More sharing options...
