This is a bit of a late posting seeing how the last post was in December of 2011. I'm relatively new to the Atari scene and I recently performed the Super Video 2.1 mod to my 600XL. For some reason I get really crisp video coming out of the Video connection on the 5-Pin DIN but it is monochrome. Not sure what went wrong here. Has anyone else seen this problem?

can you please tell me where you got the 2.0 vid upgrade?  I am thinking that this is the majority of my problem.. BTW your monochrome is probably a lack of a chromo wire

I don't know about the Super Video 2.1.  Pin 4 of the monitor jack is the is the composite pin, pin 5 is the chroma.  I installed a monitor jack using the 600XL monitor upgrade from Best, it requires soldering/unsoldering. 

I'm pleased with the results.  It comes as a kit with 13 resistors, 3 caps, a coil, 3 transistors and a 5 pin monitor jack.  The points for everything is already there, you have to clear out the solder from the holes.

You take the channel switch out and put the 5 pin jack there.  The kit is called the Jeff Popp modification, $12 ($15 minimum order).

 

looking at the female jack.

This method is way easier than SuperVideo 2.1. Has anyone done this mod, and does it give good results? I wonder if it can be "tweaked" to improve the results?

I've done it- it looks OK. I did some further mods to reduce the noise in the picture. Removed a cap, and added one from GND to 5v to filter the power to that part of the board.

 

If anything, it is *too* clear. You can see every pixel, like there is a horizontal and vertical grid. I've tried to filter it out to no avail so far...

 

There is a little further you can go for S-Video, and I haven't done that part.

 

(The moire effect is just my camera taking a photo of curved CRT)

 

Really, now that I compare it to my 800XL standard- it looks the same, so it may just be my CRT. It is a "Super Fine Pitch" Trintron.

I am pulling the chips from a 600xl and setting them up in a protoboard.  I am trying to replica my 600XL as closely as possible, but I do not want to move the RF to the proto and my 600XL does not have any other video out.  I was looking for the option that does not rely on the RF being there.  I saw Ken Sumrall and I will give that a try.  nice thread.

 

I am going to proto a 600XL then walk through a series of upgrades/mods.  Starting vanilla sans RF.
