Peritel boards

[bombidragon]

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.

Any pics you can share?

Kinda blurry but here's another one of the whole board

some better pics would be nice. How many pins on the black connector?

Peritel is an aka for SCART.

 

I'd say most likely this thing is for a TT or Mega ST/e.

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.

[bombidragon]

the output connector is a 8 pin din full size, I will get some other pics up when I can get a chance

What's written on those metal cans? They could be transistors.

[bombidragon]

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.

[31336haxx0r]

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....

[bombidragon]

It really seems like a rgb video amp, and there is a cutout for a leg inside the case.

8 pin DIN sounds like a TTL RGB connector as used on Commodore 1084 monitors.

Send me one and ill try and figure out where it fits

[puppetmark]

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.

It doesn't fit in a 400 or 800, been there done that.

8 pin Din. New pics soon hopefully

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?

Audio and composite video most likely.

Still, this thing doesn't decode chroma and luma to RGB. Hmm..
