+Larry Posted November 28, 2020 Share Posted November 28, 2020 I ran across a package that has a small board labeled "S-Video 2.1" It is about 1-1/2" X 2" and is filled with lots of resistors and caps. There are install docs, but I don't remember this video upgrade. The docs don't mention an author. I could not find anything here at AA searching "video 2.1" Does anyone remember anything about this little video mod? KJMann? An early video project from Bryan? Maybe it was a noard that had the Super Video 2.1 on it for easier installation? Incidently, does Bryan ever come around here anymore? Haven't seen anything from him in a long time.

Frankie Posted November 28, 2020 Share Posted November 28, 2020 Any chance it's this one? Quote Link to comment Share on other sites More sharing options...
+Larry Posted November 28, 2020 Author Share Posted November 28, 2020 Yes, that's the one, although mine doesn't have the connectors installed. I also have a bare pcb of this same thing. Do you know who did this? As I said, I have install docs, but no name mentioned. Why I'm interested... I have a 130XE (my very first one -- circa 1984) that has a Peterson 320K upgrade with the 256K X 1 memory chips, but the LS74158 that it uses is piggybacked on the 4050 that the UAV uses. I put the XE Super Video in this XE, and I've never been happy with the display results. So this little board might be useful for fixing the video. -Or- I might be ahead of the game to just rip out the memory upgrade. Quote Link to comment Share on other sites More sharing options...
ApolloBoy Posted November 28, 2020 Share Posted November 28, 2020 This was done by @low_budget here on AA for the 5200. 1 Quote Link to comment Share on other sites More sharing options...
Frankie Posted November 28, 2020 Share Posted November 28, 2020 They are from https://atariage.com/forums/profile/31751-low_budget/ I had them in all my Atari’s before UAV and Sophia came out. Quote Link to comment Share on other sites More sharing options...
+Larry Posted November 28, 2020 Author Share Posted November 28, 2020 Thanks! I'll search with some other video terms and see if I can find a thread about it. Any suggestions for search terms? I also see that the pcb has a 4050 on it, so this little board evidently replaces the whole computer video circuit (after GTIA). Quote Link to comment Share on other sites More sharing options...

+Larry Posted November 29, 2020 Author Share Posted November 29, 2020 Outstanding! Thanks very much! I've read through the thread briefly -- lots of good info there! It would appear that these little boards are still being sold (as linked in the thread): http://electronicsentimentalities.com/index.html Quote Link to comment Share on other sites More sharing options...

A word of advice if adding connectors: Those look like vertical connectors that were bent over. Would be better to buy 90-degree connectors, because they have the proper length after the bend. 1 Quote Link to comment Share on other sites More sharing options...
