With that I see 0.001V ripple on +5V and +10V, 0.002V ripple on -9.25V... I don't have a 2nd 850 to swap parts from, so maybe I should just order a set of 5x 3086,and 2x LM349... Did you ever get your 850 working? DavidMil Quote Link to comment Share on other sites More sharing options...

moonlight_mile Posted April 30, 2021 Share Posted April 30, 2021 So you have the most common firmware. I am not aware of revisions with problems.. do you have more info about it?I did not know about problems either. But a few years ago I was at VCF East talking to one of the people with an Atari display. I can’t remember his name but we were talking bbs and I mentioned how FoReM would crash from time to time and he mentioned that was because of the 850. He said there was a problem in the firmware/rom. Before that I had no clue. But I think in another 85o thread here they were talking about the shortcomings of the 850 software. Maybe it was The Doctor….Since these people know wayyyyy more than I I just took it as gospel. Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted July 12, 2021 Share Posted July 12, 2021 Somewhere in piles of paper I have a sheet of the revisions and problems... that is unless it's bedding for mice... it's been a great number of years... real life prevents me from putting any real time in digging most of this stuff up 1 Quote Link to comment Share on other sites More sharing options...
