bombidragon Posted December 10, 2011 Share Posted December 10, 2011 I got some NOS atari dealer parts (A box full!) and it has some atari computer peritel boards with the video output socket on one side and a header on the other. I assume these are for a 1200. The markings say: Peritel Adaptor Assy CA061034 ICTV 3-83 I figure in the US these are pretty rare and any info would be great.

sup8pdct Posted June 2, 2012 Share Posted June 2, 2012 some better pics would be nice. How many pins on the black connector? James Quote Link to comment Share on other sites More sharing options...
Rybags Posted June 2, 2012 Share Posted June 2, 2012 Peritel is an aka for SCART. I'd say most likely this thing is for a TT or Mega ST/e. Quote Link to comment Share on other sites More sharing options...
Fox-1 / mnx Posted June 2, 2012 Share Posted June 2, 2012 Not enough info (what does that connector looks like? How many pins?) and very low quality pics. Don't think anyone can say something useful about it this way. Quote Link to comment Share on other sites More sharing options...
bombidragon Posted June 2, 2012 Author Share Posted June 2, 2012 the output connector is a 8 pin din full size, I will get some other pics up when I can get a chance Quote Link to comment Share on other sites More sharing options...

bombidragon Posted June 2, 2012 Author Share Posted June 2, 2012 2n2222A , They are three legs so yeah transistors. I'm pretty sure it is RGB amp with a output but no one I have talked to knows what it goes in. Quote Link to comment Share on other sites More sharing options...
31336haxx0r Posted June 2, 2012 Share Posted June 2, 2012 Those are indeed transistors. They probably buffer some signals. STs don't have a 8 pin DIN connector for monitor/TV output. They use a 13 pin DIN connector. According to the photos this thing gets +5V and +12V. Hmmm.... Quote Link to comment Share on other sites More sharing options...
bombidragon Posted June 2, 2012 Author Share Posted June 2, 2012 It really seems like a rgb video amp, and there is a cutout for a leg inside the case. Quote Link to comment Share on other sites More sharing options...

mimo Posted November 5, 2012 Share Posted November 5, 2012 Send me one and ill try and figure out where it fits Quote Link to comment Share on other sites More sharing options...
puppetmark Posted November 5, 2012 Share Posted November 5, 2012 (edited) I think it might be for a 400 or 800. What it probably does is amplify each luma output comming from the CTIA or GTIA and then connects each one to R G B plus the SYNC signal to an RGB monitor instead of combining them for use in composite or Y-C video. It's kind of a poor-man's RGB for the Atari. So, your lumanence values now create some color on an RGB monitor. Somewhere, I have a couple of fuzzy zerox pages describing how to do this and has a schematic too. That information looks very very much like this.

31336haxx0r Posted November 8, 2012 Share Posted November 8, 2012 Well let's think of this. For RGB you need red, green, blue, ground and if the monitor doesn't sync-on-green, you'd also need sync. That makes 5 pins. I wonder what the other 3 pins are for. Are all pins of the connector connected to something on the PCB? Quote Link to comment Share on other sites More sharing options...

31336haxx0r Posted November 8, 2012 Share Posted November 8, 2012 Still, this thing doesn't decode chroma and luma to RGB. Hmm.. Quote Link to comment Share on other sites More sharing options...
